Credits --------------------------------------------------------------------------- 1. Introduction Welcome to the comp.sys.cbm "Frequently Asked Questions" (FAQ) file. Many news groups maintain a FAQ file which is posted monthly, and is a repository for general interest and common information that many readers of the news group, or new readers of the news group, might be interested in. 1.1. What is a FAQ FAQ is an acronym that stands for "Frequently Asked Questions". Shortly after the introduction of USENET, many people noticed that certain questions were repeatedly asked in newsgroups. To minimize the posting of answers to already answered questions, USENET developed the idea of FAQ files. After a question has been asked a number of times in the USENET newsgroup, it is added to the list of answered questions in the FAQ. Then, readers are encouraged to read the FAQ to cut down on posts of repeated questions. A FAQ file is not solely for newcomers. Experienced users are encouraged to glance over the FAQ every so often to check for errors and add items. Also, it seems that everyone gets a question answered by reading the FAQ, new user or not. 1.2. What topics does this FAQ cover? This FAQ answers questions on just about any topic concerning Commodore computers. Obviously, given the nature of the FAQ file, it is impossible to answer every question here, and some topics are too broad for discussion in the FAQ. However, when the FAQ cannot adequately answer a question, it does provide pointers to relevant people or materials. Even though a large number of people use their Commodore computer to program, the topic is much too broad for adequate coverage in the FAQ. For those interested in programming, however, please see Section 14, "Programming". 1.3. Who decides what goes in the FAQ? Typically, a FAQ file is editted by a single person or small group of people. These editors decide what should go into the FAQ. Obviously, for the FAQ to fulfill its intended purpose, any question that has been asked repeatedly should be included, as should updates to any questions already in the FAQ. The FAQ maintainer should try to provide as up-to-date information as possible in the FAQ. Above that, the FAQ maintainer can include any other information he or she deems or interest or value to the readers. For this FAQ, the FAQ maintainer is Jim Brain, brain@mail.msen.com, j.brain@ieee.org, or brain@acm.org. If you have information that you feel should be included, please mail it to Jim. Please be aware that it does take time to include new information. 1.4. How do I retrieve updates to the FAQ? | The FAQ is posted on the 5th of the month to the USENET newsgroup | comp.sys.cbm. It is automatically archived on the FTP site | rtfm.mit.edu and automatically archived on Jim Brain's mailserver. Most Bulletin Board Systems and User Groups have a recent copy of the FAQ, and numerous magazines and other publications have included parts or all of the FAQ on disk or in print in recent months. This FAQ is called the "COMP.SYS.CBM General Frequently Asked Questions List".

Overview Obviously, we must walk before we run, and this principle applies to FAQ files as well. Here are some general questions we often receive in the Commodore community. 2.1. Do people still use Commodore 8-bit machines? Yes, people still do. Newer machines may have appeared and taken over the corporate world, but the Commodore 8-bit machines live on. 2.2. How many Commodore machines are there? If you are asking the quantity of Commodore machines sold, the simple truth is that we do not know. Commodore never officially released any such numbers for all models. It has been estimated that Commodore sold over 10 million Commodore 64 machines, but that has not been proven, as far as I know. So, if you ever determine exactly what quantity of each model was produced, please pass the information along. If you are asking the number of different models Commodore sold, we have a slightly better idea. Jim Brain has compiled a list of all known CBM products, marketed or not, into the "Canonical List of Commodore Products". This include all of the Commodore line, including the PCs and the Amiga systems. As it is much too large to fit in the FAQ, it can be requested from Jim Brain's mailserver as file cbmmodel.txt (See Section 6.5.2 for directions on how to access the mailserver). Alternately, the file is posted to the USENET newsgroup comp.sys.cbm on a periodic basis. 2.3. What do people do with Commodore 8-bit machines? People use their machines for very different purposes: Game Console. Home Computer. Experimentor's machine. Small Business Computer. No matter what purpose they use them for, they use them because there is a wealth of programs available for the Commodore computer systems. The Commodore line of computers has a seemingly endless supply of quality programs available for it, and more are being created daily. 2.4. What Commodore 8-bit machines are most widely used? Well, it is a fact that all types of Commodore 8-bit computers are still in use, but the following machines get the most use: Commodore 64 (include SX64, DX64, and PET64) Commodore 128 (includes 128D and Euro 128D) The following systems manufactured by Commodore still have a devout following: Commodore VIC-20 Commodore PET series Commodore B series Commodore Plus 4 and 16 Commodore C65 + The Commodore 65 (64DX) The Commodore 65 is a recent addition and is the result of a liquidation of some ALPHA stage test machines. A number of people have purchased these test units, and they have a FAQ devoted just to this machine. Much information on this machine is available at ftp://ccnga.uwaterloo.ca/pub/cbm/c65 In spite of rumors, No company is considering manufacturing the C65. | If you own a Commodore C65, the following people are compiling lists of people who own them. Robin Harbon 542 West Donald Street. Thunder Bay, Ontario, P7E 5Y6 Canada + Gary Pearson + gpearson@mistral.co.uk + The Commodore PET Series If you currently use a PET series Commodore computer or just want to know more about them, one person is trying to start a magazine devoted to these machine. For more information or to submit articles for the magazine, please get in touch with: Mark J. Kingsbury 25 Latta Battle Creek, MI 49017 Mark_J_Kingsbury@fc1.glfn.org + If you own a Commodore VIC-20, the following individual is planning to + create a list of owners: + Jeff's Ink Press & Deli + P.O. Box 477493 + Chicago IL 60647 2.5. What is the economic status of Commodore? On April 29, 1994, Commodore International announced that it had been unable to renegotiate terms of outstanding loans and were closing down the business. In the months that followed, the liquidation process dragged on, owing to the large far-reaching size of the corporation. In addition, the fact that the company was incorporated in the Bahamas while a large share of the creditors were from the US made legal proceeding tense and drawn out. On April 20th, 1995, almost a full year later, Commodore was sold to a German company called ESCOM for approximately 10 to 12.5 million dollars. + In early 1996, ESCOM announced plans to sell the Amiga technology to a + U.S. company called VISCorp, while retaining the Commodore name. Then, in + July 1996, ESCOM announced that its was filing for bankruptcy protection + as it undergoes a reorganization process. The intellectual righs for the + CBM 8-bit technologare now owned by VISCorp. Of course, since Commodore hasn't served the Commodore 8-bit community for quite some time, most Commodore owners are only interested in what will happen to Commodore Semiconductor Group (CSG), the fabricator for many of the special ICs in the Commodore 8-bit line. Below is the current status of CSG as of April 6, 1995: Commodore Semiconductor Group liquidated in December, 1994. The vast majority of the operational material and the real estate was purchased by GMT Electronics, a company formed by CSG's management. GMT has paid the $1 million lien that the EPA had levied against CSG, and is now operating as a for-hire chip production plant. CSG/GMT is holding approximately $5 million in Commodore parts. 3. The BASICs These are some questions we receive about "BASIC", the built-in programming language in all 8-bit Commodore computers, and the "basics" of using the machine. 3.1. How do I format a Commodore disk? To format a disk in drive 0 (older PET drives had drive 0 and 1) on disk device #8, you issue the following command from BASIC: open1,8,15,"n0:16char_name,12":close1 | The name can be 16 characters in length, and the disk id (12 in this example) can be any two alphanumeric characters. For more information on how to use the 1541 disk drive or compatibles, a complete manual is available at ftp://ftp.funet.fi/pub/cbm/documents. (See Section 6.9 for direction on how to use ftp.) 3.2. How do I transform a BASIC program to a text file? As you may know, Commodore BASIC stores programs in "tokenized" format, so they are unreadable from a standard text editor. To fix that, load up you BASIC program, and then type the following in direct mode: open1,8,2,"listing,s,w":cmd1:list The text listing will be placed on drive 8 in a file called listing. After the listing is finished, your cursor should return. Type the following in: print#1:close1 You now have an un-"tokenized" copy of your program, which you can edit with any text editor. 3.3. How do I transform a text file into a BASIC program? Since Commodore BASIC stores its programs in "tokenized" format, one cannot simply load text files containing BASIC statements and run the file directly. However, there is a solution. In direct mode, type in the following: C64: open1,8,2,"filename":poke781,1:poke812,73:sys 65478 C128: open1,8,2,"filename":sys 65478,,1 This will read in each line of the text file and try to execute it (or store it if the line is preceded by a number). The screen will go blank (scroll upwards) while the file is retrieved and will likely end up printing an error message, which is normal. When the last line of the program is entered, hit RUN/STOP-RESTORE, and type in the following: close1 The file will now be loaded into memory. Immediately save the file to disk as a BASIC program. If the above sounds too complicated for you, check out the seq-to-basic program that is posted to comp.binaries.cbm every month. It will perform the translation for you, after you answer a few simple prompts. 3.4. How can I change my drive device number through software? To change the device number on Commodore drives, follow these steps: In the following examples, 'olddn' is the drive's current device number, and 'newdn' is the new number you wish to change it to. 1) Turn off all drives except one you wish to change device number of. 2) Type the following in, depending on drive type: 1540/41/42/4040/Most Compatibles: open 15,olddn,15 print#15,"m-w"chr$(119)chr$(0)chr$(2)chr$(32+newdn)chr$(64+newdn) close 15 MSD SD-1 (Old ROM): open 15,olddn,15 print#15,"m-w"chr$(117)chr$(0)chr$(2)chr$(32+newdn)chr$(64+newdn) close 15 1551/70/71/81 open 15,olddn,15 print#15,"u0>"+chr$(newdn) close 15 3) Turn back on other drives. The change is only temporary. It will revert back if the drive is turned off. 3.5. Can I get my 1581 drive to change its device number on startup? When the 1581 is initialized, as well as checking the boot sector of the disk, it also looks for a file "copyright cbm 86". This file, if found, can specify a device number for the 1581 disk. Whenever the 1581 is booted or initialized with this disk inserted, its device number will be changed to the specified number. The utility 1581-auto-dev by David W. Tamkin (can be found on ccnga.uwaterloo.ca in the utilities directory) will create this file. It can also do other stuff, so check it out. --------------------------------------------------------------------------- Table of Contents (for this file) --------------------------------- 4.

How do I connect my computer to the outside world? First, we need to define what "outside world" means. In this sense, we are referring to the process of connecting the Commodore computer up to another computer or computers and exchanging textual, binary, or graphical information. To connect to another computer, one must have a Commodore computer system, a modem, a phone line, and a telecommunications program (called a terminal emulator or terminal emulation program). While you can use this to connect to other individuals, to access great stores of online information you need to subscribe to an "online service", which can take many forms. This type of service allows you to correspond with many people with a single phone call, and may permit you to contact people out of your area without a long distance phone call. 5.2. What services can I use to get online? The following services can be accessed by a Commodore computer and allow the user to access online information. Bulletin Board System (BBS). - Small system usually with one phone line operated by an individual. Fees are optional. For a list of BBS systems in your area, contact Myles Skinner for a listing at mskinner@julian.uwo.ca. Compuserve Information Service. - CompuServe has two Forums designed specifically for Commodore 8-bit computer users. CBM Applications Forum (GO CBMAPP) deals with programming, geoProgramming, applications software, telecommunications, CP/M, utilities and | hardware. In addition, it also includes support for GEOS in general, music (including SidPlayer and MIDI), games, | graphics and graphics utilities. The Forum has full message | boards and extensive data libraries, and it have weekly | real-time conferences on Sundays at 9 p.m. EST. The CompuServe network is available virtually world wide. The Commodore Forums are attracting increasing membership from Europe and Australia, and have begun to tap into the vast variety of Commodore files available around the world (some of the best new Commodore programs are coming in from Europe these days). CompuServe has an extensive network of local numbers throughout the United States and Canada and is also available through supplemental networks such as SprintNet and DataPac. The number of direct CompuServe connect numbers in Europe is beginning to expand. While there is no standalone CompuServe navigator program available for Commodore users, CBMAPP has the CIS.EXE script set that automates Dialogue 128 on CompuServe, and also VIDAUT.BIN which will virtually automate Vidtex (which is available again through Software Support International). In addition there is OFFLIN.HLP, a text file in CBMAPP, that provides a method for semi-automating access with any standard comm program and word processor. CompuServe's rates are as follows: STANDARD PRICING PLAN Membership Support Fee: $ 9.95/month PLAN BENEFITS For $9.95, your CompuServe membership entitles you to five free hours on the service. This includes forums, mail, and Internet access. After your first five hours, additional hours are billed at the rate of $2.95/hour. For an additional $15 a month, our Super Value Plan adds 15 free hours (for a total of 20 hours each month) and each additional hour is just $1.95. Premium ($) services carry additional surcharges, however, during your free hours, you are not charged for connect-time. Any communications surcharges apply. INTERNET ACCESS Direct Internet Access (Dail PPP) File Transfer Protocol (FTP) Remote Login (Telnet) USENET Newsreader ASCII USENET Newsreader CIM For additional information on the listed services, GO INTERNET. MAIL CompuServe Mail is billed for connect time. This includes reading mail and viewing classified ads. Surcharged areas, such as fax, telex and CongressGrams carry additional charges. For a complete list of mail services and rates, including hardcopy deliveries through the postal service, GO MAILRATES. CONNECT-TIME RATES Connect-time is billed in one minute increments, with a minimum of one minute per session. Partial minutes are rounded each log-in session to the next full minute for our billing purposes. Compuserve Information Systems P.O.

The Commodore support area on GEnie is known as the Flagship Roundtable. While there are a few premium services on GEnie that charge an extra price, all of the Flagship is available at the basic rate. The Flagship RT includes some "Real-Time Conferences" (RTCs) featuring classes or discussion of issues associated with Commodore computers. Additionally, there is a BB (Bulletin Board), which works much like Usenets comp.sys.cbm (only the discussion is broken down into categories and topics). Finally, the Flagship has an extensive library of Commodore files. The BB messages can be read economically by capturing all the new messages in a terminal programs capture buffer, and reading the messages off-line. Wizard, the C= GEnie fron end, supports this. Because GEnie is a general interest service,it supports many different computers, and you can use any ASCII terminal program to connect to GEnie. Wizard is available, but not required. GEnie operates normally | at 300 - 28,800 bps. There are local access numbers across the country. GEnie 401 North Washington Street Rockville, MD 20850 (800) 638-9636 (Information) Delphi Internet Services. - Delphi is a commercial system that, while small in comparison to other systems, is growing rapidly. It has a large forum dedicated to Commodore computers, as well as access to the Usenet and the comp.sys.cbm newsgroup. Delphi has two plans. One, called the Standard Plan, costs $10.00 a month and gives the user 4 hours of non-prime time (6PM-7AM) free each month. Each additional hour is $4.00. The other plan, called the Advantage Plan, costs $20.00 a month and gives the user 20 hours of non-prime-time free each month. Each hour over 20 is $1.80. Access to the Internet via Delphi costs an additional $3.00 for both plans each month. Delphi Internet Services 1030 Massachusetts Avenue Cambridge, MA 02138 (800) 695-4005 (Information) Internet - The largest online service. The Internet is a collection of 4 million machines interconnected using a common protocol called TCP/IP. This service is the result of a U.S. defense experiment started in the late 1960's. Due to its distributed nature, the Internet is unlike most other online services. In some cases, as in universities, there is no cost to access the "net", as it is called, and some other online services offer access to the Internet. This is the home of all the FTP sites, the USENET and the USENET newsgroup comp.sys.cbm, Internet email, and the World Wide Web. When you use these services you are utilizing the Internet. QuantumLink - Q-Link was a Commodore specific telecommunications service. This service, while booming in the late 1980's, has now been discontinued. There was an effort to retrieve as many of the QuantumLink files as could be retrieved. Email Brenda G4 at b.gann1@genie.geis.com | for more information. Also, a list of ex-Qlink-ers is being | maintained. If you want to be on the list, send email to | steward@pobox.com or sirfitz@kaiwan.com. 5.3. What hardware do I need? To access online services you will need a functional Commodore computer that is physically able to have a modem of some kind attached to the computer. The more common C64 and C128 are able to be used with a modem, but computers like the Commodore C16, C116, some PETs and some older CBM business machines may require significant investments in order to be used. With a functional computer, you will need a modulator/demodulator (modem) unit of some kind. There are two basic kinds that can be used on the Commodore computers: A standard RS-232 (EIA-232) external modem. These modems are very common in today's market, as they are usable on all computer systems. They usually are constructed in a small rectangular box, have lights across the front, and have either a standard 9 or 25 pin D-style connector on the back of the unit. Speeds range from 300bps to 28,800 bps and above. This modem requires an interface cable of some kind to connect to the Commodore computer. A Commodore compatible external modem. These modems are much less common in today's market. Originally manufactured only by Commodore, some examples include the C1600 (300bps manual dial), C1650 (300bps, pulse dial), C1660 (300bps, DTMF dial), and C1670 (1200bps, AT commands, DTMF/Pulse dial). Although other companies manufacture compatible modems, it seems that the maximum speed is 2400bps for all models. This modem style plugs directly into the Commodore user port. Please note that all speeds marked are maximums. Most modems will operate at any speed up to the maximum. Most users agree that buying a Commodore compatible modem these days is an unwise move, except for special circumstances. The suggestion is to purchase a standard modem and an interface to use the modem with the CBM machine. If you chhose to purchase a standard external modem, you must also purchase or build a suitable interface. There are two major types of interfaces: Simple Cable Interface. This type of interface merely converts the nonstandard RS-232 pinout on the Commodore user port to the standard RS-232 pinout and performs voltage level translation as required by RS-232 specifications. This interface can be purchased for $20 to $40 new or built by the user. There are a number of homemade interfaces available. The TRANSACTOR published an interface in the Nov 87 issue (V8iss3) and Commodore Hacking Online Magazine published plans for one in issue 4 (See MailServer section for retrieval instructions. These are both supposed to emulate the VIC1011A that C= put out many years ago, and you might find one at a computer "flea market". Another version is designed by Stephen Coan. | Send email to Fred Mueller (fred.mueller@lucent.com) for a copy of | the schematic in ASCII format. The differences between the two is the | Transactor one has switchable options for some of the leads and the | Coan one is hard wired. (See Section 12.4 and 12.5 for interface designs) UART interface. To use a modem, a Universal Asynchronous Receiver Transmitter (UART) is needed. When Commodore designed the CBM VIC-20, C64 and C128, they emulated a UART in software to keep costs down. Although this works for slower speeds, there is a limit to how fast the software UART can function. For faster access, a real UART is needed. This type of interface provides a complete UART in a cartridge that plugs into the expansion port. To utilize it, all software must be written to take advantage of the real UART. UART interfaces can be purchased from CMD (Swiftlink), HART (HART Cartidge), or built from plans (DataPump). (See Section 13.6 for addresses and further information on UART cartridges.) The decision of which interface to buy depends on the speed of your modem and the software you are using. The software UART on the Commodore 64 can handle speeds at up to 2400 bps. The software UART of the Commodore 128 can handle speeds at up to 4800 for all software and 9600 bps for some very well-written software. If you are under these maximum limits for your system, the simple interface cable will suffice, and most terminal programs can be used. For speeds between 2400 and 9600 bps (4800/9600 and 19200 bps on a C128), a number of options are open. Some programs can use the simple interface cable to allow this faster access. Newer terminal software may be written to exploit Daniel Dallmann's 9600 bps access technique, which requires some small modifications to the simple interface cable (see Section 12.5 for more information). Finally, some programs allow the use of a UART cartridge. For speeds above 9600 bps (19200 on a C128), a UART interface and an appropriate terminal program is your only option. 5.4. What kinds of terminal programs exist? There are many types and versions of telecomunications programs (referred to as terminal emulation programs or terminal programs). Some are better than others, but individual users will ultimately decide which they like best. Most terminal programs available today are Shareware, but some are still sold commercially, and some new commercial terminal programs are being sold. All of these programs include emulations of the popular terminals such as DEC VT100, VT102, VT52, and ANSI. Also, each includes a number of file transfer protocols (See Section 6.1 for more information on transfer protocols). 5.4.1. What kinds of terminal programs exist for the 64?

Can I use my Commodore computer on Amateur Radio? Yes you can. If you want to use your CBM system as a terminal for a standard RS-232 compatible packet radio Terminal Node Controller (TNC), you can hook it up in the same way as a modem. See Section 5 for more information on how to connect your Computer to a modem. In addition, the ICHPUG User Group (see Section 15 for address) has an extensive library of files for the C64/128 relating to Amateur Radio.

Is there TCP/IP software available for Commodore computers? Unfortunately, there is none at this time. However, the following information is available: Jim Brain has performed tests that demonstrated the ICMP and IP protocol layers. Daniel Dallmann has now verified these tests and both of them, as well as Cameron Kaiser, are independently working on a TCP/IP protocol stack for the Commodore 64. --------------------------------------------------------------------------- Table of Contents (for this file) --------------------------------- 6.

What is a file extension, and what do they stand for? --------------------------------------------------------------------------- 6. The Online Information Reservoir How true this is. There is information everywhere online, just waiting to be accessed and used. Hoever, getting at the information can be a time consuming process. 6.1. How do I download? What is a transfer protocol? To transfer files for another computer (another 64 or 128, UNIX, OS/2, DOS, MVS, VMS, Amiga, Atari, or other), you should use a transfer protocol. Although it is possible to transfer files by turning on the terminal program's capture buffer and receiving the file, this is not very reliable and is prone to errors. When transferring any sizable amount of data, one should use some sort of error-correcting file transfer protocol. A file transfer protocol splits a file into many pieces, or "packets", and send a number of them at a time. It then waits for an acknowledgement from the receiver that the received received the packets correctly. At this point, the sender send the next batch of packets. This process is repeated until the entore file is transmitted. Each packet contains computed checksums and other error detection bytes to ensure the received data is not corrupt. Below are descriptions for some of the more popular protocols: C1 (commonly called Punter Protocol) C1 is a Commodore specific transfer protocol that used to be the standard for file transfer. However, with the increase in IBM-based bulleting board, it has been replaced by other protocols. Most Commodore BBS systems still offer C1 (usually called Punter in the list) as an option, but almost no other BBS systems have support for it. There is, however, a C1 protocol transfer program for MS-DOS called puntr104.zip. KERMIT KERMIT is the name of one of the oldest file transfer protocols. KERMIT is unique in that it can encode the file being transmitted so that it does not contain any bytes greater than 128 and does not contain any special control bytes that terminals use to perform special actions. As such, this protocol is the most robust, but it is also the slowest. A common statement is, "if you can't KERMIT it, you can't get it" XMODEM XMODEM comes in several varieties. Standard XMODEM sends files in 128 byte packets. There are two standard error-correction methods with XMODEM checksum and CRC. CRC is the more modern of the two. There is also a version of XMODEM which supports 1K-byte packets. This version is most commonly known as XMODEM-1K, but is sometimes erroneously called YMODEM. YMODEM YMODEM is a "batch" XMODEM protocol, allowing you to transfer multiple files in one operation. ZMODEM A new file transfer protocol is ZMODEM. ZMODEM is theoretically the fastest transfer protocol, but only shows a speed gain over the others on noise-free telephone lines. It achieves this speed increase by only replying to the sender about the bad packets. Most terminal programs support PUNTER, XMODEM, XMODEM-1K, YMODEM, and KERMIT. The Kermit terminal program only supports KERMIT, and Novaterm, as of version 9.5, supports ZMODEM receives, but not sends. 6.2. What is the difference between PETSCII and ASCII? (Note that the Amiga line of computers uses the ISO 8859-1 character set, so this does not apply to Amiga computers) When Commodore designed the PET line of computers, they chose for the character set encoding a special encoding called PETSCII. This set is similar but not the same as the American Standard Code for Information Intercahnge (ASCII). Now, this does not cause any problem when transferring information between or among Commodore computers (except the Amiga, which I believe uses ASCII), but causes problems when exchanging information with othe computer types. The obvious solution is for all Commodore users to translate incoming information into PETSCII from ASCII when talking to another type of computer. However, this effectively ruins binary files, which have no concept of character codes. Therefore, the rules are: Do not translate when exchanging binary files with any computer Translate all textual information exchanged with non-Commodore computers. Translate textual information exchanged with Commodore computers only if they are translating it as well. If a text file you retrieve looks like the uppercase letters should be lowercase and vice versa, then the file is in ASCII and needs to be converted to PETSCII. 6.3. Where can I find Commodore programs? Commodore programs are available from a number of sources. For commercial software, please see Section 15.1 for a list of software dealers. For shareware and public domain, you can use FTP (Section 6.9), electronic mail (Section 6.5.2), and bulletin board system in addition to the software dealers to download or buy programs and other software. 6.4. What is a file extension, and what do they stand for? A file extension is a 1 or more letter suffix appended to the end of a file name to indicate the type of file it is. The extension usually indicates the contents of a file. The list below describes some more common file extensions, what they are used for, and how to use the file. Please note that these file extensions are not Commodore-exclusive. Many computers use file extensions. Also note that some file extensions are cumulative. IF a file is named "filename.tar.gz", this indicates that the file is of type "gz", and the file(s) inside the gz file are of type "tar". To use this file, one would note that both extension are archival extensions. One would undo the "gz" archival method to restore the "filename.tar" archive, then undo the "tar" archival method to restore the original file. Extension: Meaning: Notes: ----------------------------------------- .txt Text File This file is not compressed, so it needs no decompression step. However, the file may be in either ASCII or PETSCII format, so a conversion step may be necessary. Most terminal programs can do this conversion, and there are stand-alone programs that do the necessary conversion also. .sda Self-Dissolving Just load and run the .sda file to Archive dissolve the archive. Will dissolve itself into its constituent files. C64 and C128 .sda files are not compatible with each other. .sfx Self-Extracting Load and run just like a .sda file. Archive The same archive can be extracted on either a C64 or a C128, memory permitting. .arc ARChive Use the program arc250.4 or earlier for the 64 or arc128 for the 128 to dissolve the archive. arc128 is available as part of the CS-DOS package. Other de-archive programs may exist. .lzh LHArchive Use the program lhx in CS-DOS on the 128 to dissolve this archive. These are not very common. This archive uses the same format as .sfx files, but is not self-extracting. It is a standard format also used by Amiga (and MS-DOS) computers. This format originated on the PC. .lnx Lynx Archive The above formats all compress files when storing them; Lynx just stores them. There are many different versions of Lynx out there, so good luck dissolving these. .lbr Library Archive A format similar to lynx. Library dissolving programs exist for both the 64 and 128 to dissolve these. .uue UUEncoded file UUencoding is a process whereby a binary file can be converted to an all-text file, transferable by E-mail. This encoded file can later be UUDecoded back to the original binary file. Unix has uuencoding/decoding utilities. A program "uuxfer" for the C64 (by Fuzzy Fox) will both uuencode and uudecode. Note that the contents of uue file could be another archived file. .uua UU archive An extension of uuencoding, a uuarchive file is a concatenation of one or more UUEncoded files. So far as I know, this was introduced by Craig Bruce in his ACE shell for the C=128, and the utilities included with that shell create and dissolve uuarchives. .kar Kevin's Archive Another text archive format that seems to have originated with Craig Bruce, this is a proscription for concatenating a series of text files (which can include uuencoded files) into one file. More information can be found in C. Bruce's documentation for his ace shell. x! ZIPCoded file ZIPCode is a program that takes an entire disk and "compacts" it into 4 files that have a number followed by a '!' and then a filename. Also, ZipCode can compress files, in which case the x is a letter (a,b,c,d) and there need not be 4 files. If ZipCode has compressed individual files, there will be an "i!" or "x!"-prefixed file on the disk that holds the directory of the file compressed. To make things even more confusing, there are two versions of ZipCode (v1 and v2). The newer version will accept v1 archives, but not vice-versa. Use ZipCode v2 to unpack such archives. + _x.z64 ZIPCoded file These are ZIPcode compatible files + created by a DOS program called Star Zip x!! ZIPCode 6-pack This is a ZIPCode archive that takes an entire disk and puts it into 6 files, | each file containing GCR codes and header info for the tracks. This is basically a nybble copier that stores the data it receives from the disk into files. .bco BCODEd file BCODing is very similar to UUencoding in that a binary file is converted into an all-text format that is 33% larger than the original. The difference is that the BCODE format provides additional information for error detection and automatic data segmentation and reordering. C-code versions of "bcode" and "unbcode" are available via FTP and Commodore versions are provided with ACE-128/64. .zip ZIP archive Zip is a file format used on IBM platforms and is created by the PKZip program that is available for some platforms. There are two forms of zip files that have the same extension. Both are created by different versions of PKZip. The first, version 1.01, can be dissolved on a 64 by using the program UNZIP64. The second, newer format is version 2.04, which cannot be dissolved by UNZIP64. Your best solution when in doubt is to dissolve the files on another platform. For the 128, there is a version of the UNZIP64 program, called UNZIP128 that has been modified to run in 128 mode. It is in a file called NZP12817.SFX. This archive also has a 64 version. ]x Compression Kit x = 4,7,8, cmd, or c(xx) to denote type Archive of media that was compressed. The files can be extracted only with The Compression Kit, from Mad Man Software. .tar TAR Archive UNIX Tape ARchiver. This program can be used to archive files as well. The file must be decoded using tar. .Z Compress archive Compress is a program on UNIX that will shrink a single file. It is usually used on .tar files in UNIX to reduce their size. The file must be decoded by the uncompress program, available on UNIX, PC, Mac and other platforms. Also, a very old version of GNU Zip used this extension, although the file is not fully compatible with the compress format. .gz GZIP Archive GZIP is a free program developed by the Free Software Foundation to freely shrink their software. the resulting file must be decoded by GUNZIP, available on many platforms, before using. .taz Compressed TAR This is a file that should have the extension "tar.Z", but has been shortened for MS-DOS. Run uncompress, then tar on this file. .tgz Gzipped Tar File This is a file that should have extension tar.gz, but has been shortened for MS-DOS Run gzip or similar on the file, then tar. .gif Graphics This is a compressed graphics format Interchange created by Compuserve. To view this file, | Format one must find a GIF viewer program: + GEOGif.SFX - Converts GIF to GEOPaint. + VGIF.SFX - 64 mode viewer. + GDS.SFX - 128 mode viewer. .jpeg Joint This graphics format can use one of two Photographers compression algorithms. One, called DPCM Expert (Differential Pulse COde Modulation) Group retains all of the information in the original file, which is usually a picture. The more common algorithm, called DCT (Discrete Cosine Transform), relies on the inability of the human eye to distinguish among some colors. DCT "throws away" some information in the file (picture), while still retaining the essence of the picture. To view these pictures, one must either obtain a JPEG veiwer or convert them to GIF format. .jpg JPEG This is an MS-DOS named .jpeg file. .tiff Tagged This is a graphics format used on high Image performance workstations. To view this File graphics format, you will need to convert Format something else. .pcx IBM Picture This is graphics format used in DOS on IBM machines. Convert this file to a GIF file to view. .pict Mac PICTure This is a graphics format used on Apple Macintosh machines. Convert this file to a GIF file to view. .d64 1541 Disk Image This file stores an image of one entire .x64 disk, for use with Commodore emulator programs. Several programs exist to extract the image onto a disk or place a disk onto an image. The only difference between the .x64 and .d64 file types is an added 64 byte header on a .x64 file. .t64 DataSette Image This file is analogous to the .d64 file type, but for tapes. .p00 PC64 (Emulator) This file encapsulates a Commodore program Program File Image or data file. To extract the original file, remove the first 26 characters. In addition to .p00, there is .s00 (SEQ), and .u00 (USR) files, but are very rare. .bmp Windows Bitmap This is a format used for graphics in Microsoft Windows and OS/2. Convert this file to a GIF to view. .pbm Portable Bitmap .xbm X bitmap This is a format used for graphics on the X windowsing system. Convert this file to a GIF to view. .html HyperText This is a WWW hypertext document. To Markup view this file, you will need a WWW Language browser of some kind. See Section 6.8 for more information on WWW. .doc Document This file could be a word processing file from a program like Word for Windows, Wordperfect, or any other word processor. Also, some text files that contain documentation use this extension. .cvt GEOS file GEOS files use a special file format. The files are called USR files, but they have special information in the file that normal files don't, so you cannot just upload a GEOS file like any SEQ or PRG file. You can pack all the extra information and the data into a regular Commodore SEQ or PRG file with a program Called Convert. It has a version 2.5 and a 3.0. The files that result from this conversion have the extension. The file must be processed again by Convert before it can be used with GEOS. .N64 64NET file Since the 64NET system works by allowing an MS-DOS machine to be used as a large disk drive, a way was developed to map CBM filenames into the MS-DOS limitations. The .N64 filenames indicates such a file. + .D71 64NET GEOS File These are 64NET extensions used to + .D81 emulate a 1571 and 1581 disk drive, + respectively, under GEOS. If the file type indicates an archive, there are many programs available that will handle most archival methods. One of these is called Omega-Q II, which includes one-stop compression and decompression of many of the above archival types. If you use a host system to download the files from, you may want to decompress the files before downloading. Even though the files will be larger to download, the time to decompress them offline will not be a factor. However, those who pay by-the-minute for download time would probably want the smallest possible file, which implies decompressing on the local machine, except in the case of a UU encoded file. These files are actually bigger in the 'UU' format. --------------------------------------------------------------------------- Table of Contents (for this file) --------------------------------- 6.5.

What else is available online? --------------------------------------------------------------------------- 6.5. What is electronic mail? Electronic mail is the online equivalent of post office mail. Although email is a general term, its use is usually meant to mean "Internet email". To use email, you must have access to an internet email program. On UNIX, these programs are called mail, elm, or pine. BBS systems usually have a special message area for Internet email. You address a message to a user by using his or her internet email address, which is usually of the form name@machine_name.doamin_name.type_of_institution_or_country. An example would be brain@mail.msen.com, which would be user "brain" at machine "mail" in doamin "msen" and the type "com" which means company or commercial. After addressing the message and choosing a sutiable subject, the body of the message is written with information meaningful to the addressee. Usually this information is textual in nature and reads much like a personal letter. It is possible to mail people binary files. To do this, you need access to a program called uuencode. Most, if not all UNIX machines have this command available, and there are versions available for IBM, Amiga, and Macintosh. There is also a version of uuencode available for the Commodore 64 and 128 as part of the ACE 128/64 OS replacement. (See section 8.3) The uuencode program takes a binary file and expands it so that it only contains 7-bit ASCII characters. This resulting file can then be mailed to a recipient, who then uses a similar program called uudecode that will transform the uuencoded file into the resulting binary file. This encoding technique is a standard one used across multiple platforms. If you want to send a file to another Commodore owner, you can use bcode, which is a Commodore-specific encoding available in ACE 128/64. 6.5.1. What are mailing lists and how do I join one? A mailing list is similar to a USENET newsgroup like comp.sys.cbm, in that it provides a place for people to talk among each other and ask questions. The difference is that the mechanism used is mail. You mail a message off to the list, the message then gets sent out to all members of that list, they read and reply to the list, and the process repeats. It is used for topics that are considered temporary or topics that have a limited scope and may not sustain an entire newsgroup being devoted to them. It may also be used when people want to privately discuss some issue. There are a number of Commodore 8-bit mailing lists for you to join: cbm-unix - This is a list devoted to the discussion of alternate operating systems for the Commodore line that have the familiar UNIX shell look-and-feel. You can join this one by sending mail to mailserv@lists.funet.fi with the message: subscribe cbm-unix Jim Brain review cbm-unix help you can then send mail to the list by addressing it to: cbm-unix@lists.funet.fi. old-cbm - This is a list devoted to discussions of older Commodore equipment. Typically, this list discusses issues concerning PETs, the VIC-20, Plus 4 and C16, and other lesser used machines.

What is a Mail Server? How do I use one? A couple of people are running servers that will respond to email requests. Each have a limited amount of files available. To access them send the following email: To: brain@mail.msen.com Subject: MAILSERV Message Body: help quit That will return a list of commands. Currently the following commands are supported: help retrieves a list of available commands. catalog retrieves a list of files currently available. send retrieves the file subscribe list_name Firstname Lastname subscribes the user to a mailing list. 6.5.3. How do I contact people on Compuserve, Genie, etc.? These online services have gateways to the Internet. To send a message to someone on the following services, make sure they can receive Internet mail and address the message as follows: Service Username Internet Address Compuserve 12345,678 12345.678@compuserve.com GEnie j.smith2 j.smith2@genie.geis.com Delphi jsmith jsmith@delphi.com FidoNet is special, since there are many fidonet nodes, so you need the specific node information for the system that the recipient is on. Assume that Jim Brain is on a fido BBS that is node 115 on network 233 in zone 1. (denoted in FIDO as 1:233/115) The address would be: FidoNet Jim Brain Jim.Brain@f115.n233.z1.fidonet.org If the fido address is a point on a FIDO network (denoted as 1:233/115.200), then the address would be: FidoNet Jim Brain Jim.Brain@p200.f115.n233.z1.fidonet.org 6.6. What is USENET or NetNews? What is a USENET newsgroup? USENET is a service on the Internet that presents the user with a variety of forums in which to place messages. It can be viewed as the online equivalent of a set of bulleting "corkboards", like those in a hallway. Each corkboard or "newsgroup" caters to a different topic. Users can place or "post" messages to the newsgroup for others to read, or followup to posts on the newsgroup. 6.6.1. What news groups cater to Commodore 8-bit machines? The first thing to discuss here is the dividing line between Commodore models. All Commodore computers up to, but not including, the Commodore Amiga or the Commodore line of IBM PC Compatible computers, are discussed in comp.sys.cbm, which is what this FAQ covers. The Amiga line of computers is covered in the separate newsgroups comp.sys.amiga.*, where the '*' indicates that there are a number of groups that match that name. The IBM PC Compatible computers are discussed in comp.sys.ibm-pc.*. comp.sys.cbm - This unmoderated newsgroup discusses all topics concerning Commodore 8-bit machines, including everything from the KIM-1 to the Commodore 65. This is the flagship USENET newsgroup. comp.binaries.cbm - This moderated groups permits the distribution of uuencoded binary files for the Commodore 8-bit computers. The moderator is Mike Miller (mmmiller3@gac.edu). If you have a favorite program you wish to put up for distribution, please download and read the comp.binaries.cbm FAQ (posted in its respective group). comp.emulators.cbm - This unmoderated newsgroup was created in 1994 for those who wish to run one of the many emulation programs available on other machines that emulate the C64. This forum seems to be more appropriate for questions concerning operation on "foreign" hardware and file types. zer.z-netz.rechner.c64+c128.allgemein - This is a German newsgroup that discusses much of the same topics as comp.sys.cbm. "allgemein" = general. zer.z-netz.rechner.c64+c128.binaer - This German newsgroup parallels the function of comp.binaries.cbm. "binaer" = "binary". zer.t-netz.c64 - This is a general discussion group for the c64 computer. It has the description 'Der am weitesten verbreitete Rechner', which means "The most widely used/most popular computer." zer.z-netz.rechner.c64+c128.hardware | This German newsgroup discusses hardware topics relating to the C64 and C128. + zer.z-netz.rechner.c64+c128.programmieren - + This german newsgroup discusses programming, mostly demo stuff. + zer.z-netz.rechner.c64+c128.spiele - + This german newsgroup discusses games, high scores, tips, new releases, + old scores, etc. + zer.z-netz.rechner.c64+c128.virus - + This german newsgroup discusses the very few viruses that have been + created for the 64. 6.6.2. What types of discussions belong in comp.sys.cbm? Any discussions about Commodore machines excluding the Commodore Amiga line, the Commodore IBM PC Clone line are encouraged in comp.sys.cbm These machines are commonly referred to as the Commodore 8-bit line, whereas the Amiga and PC line is not 8-bit. Please make sure any question you intend on posting is not already answered in this FAQ. Also, when posting a troubleshooting question about inoperative equipment, please give as much detail as possible. Be considerate of others in the group and keep questions not pertaining to some aspect of Commodore 8-bit machines and peripherals out of comp.sys.cbm. The group does realize, however, that a large percentage of Commodore 8-bit owners also own another computer system and might have questions about interfacing or emulations. Just use your own good judgement. 6.6.3. Which issues does comp.sys.cbm discuss regularly? Although comp.sys.cbm discusses all Commodore 8-bit machines at times, the C64 and C128 get most of the attention. An overview of the subjects discussed in comp.sys.cbm is available at http://qiclab.scn.rain.com/pub1/overview/comp/sys/cbm/.overview 6.6.4. How do I post in comp.sys.cbm? You first need to access the newsgroup comp.sys.cbm through the use of newsreader. There are many available in UNIX with names like rn, nn, tin, and trn. I can't begin to tell you what command each uses to construct a posting, but your machine administrator should be able to tell you. All posts should contains relevant Summary and Keyword info, as well as a descriptive title. If you are posting a followup to an existing article, and are quoting the article, please only quote the relevant portions of the existing article. If you find that you cannot post to a newsgroup via your newsreader, but do have Internet electronic mail capabilities, you can post to the newsgroups via e-mail. For example, to posts a message to COMP.SYS.CBM, simply mail the message to either comp.sys.cbm@anon.penet.fi , comp.sys.cbm@news.demon.co.uk, comp.sys.cbm-news@newsbase.cs.yale.edu. It is probably best to use the latter two addresses, since the other is an anonymous posting service, so people won't know who originated the post. Such disguises are unnecessary in the CBM newsgroups. | 6.6.5. How can I read comp.sys.cbm through email? If you do not have access to the USENET newsgroup comp.sys.cbm and do have access to Internet email, Allen Smith has graciously set up a list server that will mail each day's postings to you. To use this service, email listserv@compsmth.soonet.ca with NO subject and ONLY SUBSCRIBE comp-sys-cbm in the body (no leading spaces, no signature) to use this service. + Jim Brain has graciously set up a server for those without USENET access + to read the three main CBM newsgroups: comp.sys.cbm, comp.emulators.cbm, + and comp.binaries.cbm. Again, this service is ONLY for those without + other means to read USENET. To use this service, email brain@mail.msen.com + with the subject of MAILSERV and the following in the message: + subscribe comp.sys.cbm Firstname Lastname msglen* + msglen is the maximum number of lines you can receive in an email message. + All fields MUST be filled in. + To subscribe to one of the other 2 CBM newsgroups, substitute the + newsgroup's name for comp.sys.cbm in the above line. | 6.6.6. How can I read comp.sys.cbm through WWW? + (See Section 6.8 for a definition of WWW) + You can view articles and articles titles through the DejaNews service: + http://dejanews.com/ 6.7. What is a FidoNET echo? FidoNET is a "grass roots" network that originated to link bulletin board systems across the country together. Unlike the Internet, which uses dedicated phone lines at high speeds to implement its network, FidoNET uses regular phone lines at normal modem speeds that are not dedicated to providing networking to link the machine on FidoNET together. FidoNET allows the exchange of messages in message bases called "echoes" among various boards. To use the FidoNET echoes, you must connect to a system that has FidoNET access. It is not possible to describe all the features of FidoNET in this FAQ, so you should consult your local User Group or BBS sysop for more info. The FidoNET echoes are similar to USENET newsgroups, although the echoes have more strict rules about content and topics. 6.7.1. What echoes cater to Commodore 8-bit machines? The relevant echoes for Commodore users are: CBM Commodore 64 and 128 News and Discussions | CBM-128 Commodore 128 specific News and Discussions | CBM-GEOS GEOS News and Discussions PCWRITE Cross Platform Computing, including C64 emulators CBM.GER German Fido area for CBM discussion. R20_8BITAR Sweden echo for all 8-bit CBMs. 6.7.2. How do I post in an echo? Echoes are usually posted in the same way that you would mail a BBS message in any other area, although the BBS may operate differently. It is best to follow any online directions or consult the local BBS sysop for more details. 6.8. What is the World Wide Web? The World Wide Web (WWW or W3) is a Internet-wide Hypertext document retrieval and display system. To use WWW, you must have access to a WWW HyperText Markup Language (HTML) browser. Typical examples include lynx, which is a ASCII browser available on UNIX, and Mosaic, a GUI browser available for UNIX, Windows, Mac, and other platforms. There are others, but these are a few. Once in a browser program, point it at some of these WWW "pages". If you do not have WWW access to the Web, you can request pages be mailed to by sending mail to webmail@curia.ucc.ie with the subject help. The return mail should tell you how to request a WWW page. However, if you do have access to telnet on the Internet, you can access the Web. Instructions on how to do this, in a file called wwwtelnet.txt, can be retrieved from Jim Brain's MAILSERV server. See Section 5.X for information on how to access the server. + All pages on the WWW are referenced by their Uniform Resource Locator, + also known as a URL. The URL normally looks like: + http://name.of.site.com/path/to/page.html + Some sites include a funny character that looks like a "squiggly snake" + as the first character of the path. The squiggle looks like this: + ~ + The charcater is referred to as the "tilde" character. + This key does not appear on the Commodore 8-bit keyboards, and is + not part of the PETSCII character map, so the character above will look + funny if viewed on a CBM computer. When one is running a terminal + program, the program remaps a key to be the tilde key. Here are a few + mappings for different programs: + Novaterm: [SHIFT] up-arrow + If your terminal program does not remap a key to be the tilde, or if + you dislike trying to use the remapped key, the URL spec defines that the + hexadecimal equivalent of the character can be used, prefaced with the + percent sign. So, instead of "/~brain/", one can use %7E instead, + resulting in "/%7Ebrain/" as the URL. 6.8.1. What WWW sites have Commodore information? There are a number of WWW sites that provide Commodore content. Most of these sites are tailored to the Commodore 8-bit community as well. | A complete listing of sites is available at CaBooM!, a Commodore meta- + index at: | http://www.msen.com/~brain/cbmlinks/ 6.8.1. What Sites have Telnet WWW Browsers? If you do not have access to a WWW browser program, but do have access to Internet telnet, you can access the WWW through the following sites: fatty.law.cornell.edu www.njit.edu lynx.cc.akans.edu login: www 6.9. What is File Transfer Protocol (FTP)? to access some machines, the special user "anonymous" or "ftp" is used to log into another machine for ftp. These machine, which hold public domain (PD), shareware, and freeware files, are called "anonymous ftp" sites. To get files from these sites, you use (on most systems) a program called ftp. A typical ftp session (assuming you are running from a Unix system) would be as follows: SAMPLE SESSION: %ftp ccnga.uwaterloo.ca Connected to ccnga.uwaterloo.ca. 220 punisher FTP server (SunOS 4.1) ready. Name (cco.caltech.edu:rknop): anonymous 331 Guest login ok, send ident as password. Password: 230 Guest login ok, access restrictions apply. ftp> cd /pub/cbm/utilities <"cd" changes directory> 250 CWD command successful. ftp> dir z* <"dir" alone lists whole directory> 200 PORT command successful. 150 ASCII data connection for /bin/ls (131.215.48.57,2084) (0 bytes). -rw-r--r-- 1 root root 15427 Apr 13 15:42 zed-128.070 -rw-r--r-- 1 root root 14107 Apr 13 15:42 zed-128.doc 226 ASCII Transfer complete. remote: z* 134 bytes received in 0.44 seconds (0.3 Kbytes/s) ftp> binary 200 Type set to I. ftp> get zed-128.070 200 PORT command successful. 150 Binary data connection for zed-128.070 (131.215.48.57,20) (15427 bytes) 226 Binary Transfer complete. local: zed-128.070 remote: zed-128.070 15427 bytes received in 0.1 seconds (1.5e+02 Kbytes/s) ftp> quit 221 Goodbye. % To submit files to an ftp site, you use the command "put". Again, make sure to first specify "binary" for programs and other binary files. Typically, ftp sites will only accept submissions in an "INCOMING" directory. To download software (files) from an anonymous ftp sites, one has to be aware that there are two connections to be concerned about. The first connection is from your Commodore to you host computer and then the connection from your host to the ftp site. In addition you need to be be aware of the nature of the information in the desired file, particularly if you are downloading programs. If the file is not known to be in printable ASCII form, consider it a binary file. It may also be be in an archived form, i.e. a form where it is packed with many files or in a shortened format. Consider these to be binary unless it is of the "uu" type which is an ASCII format. 6.9.1. What FTP sites have Commodore Information? A number of sites on Internet have areas for Commodore files. The list of current Internet FTP sites can be retrieved from the Jim Brain's mail server as file cbm-ftp-sites.MM.YY where MM is the Month and YY is the year that the list is for. (See Section 6.5.2 for directions on how to use the mail server). The FTP List is maintained by Howard Herman and a copy of the latest file can be obtained from him at 72560.3467@compuserve.com. 6.9.2. What is an FTP Mail Server? How do I use one? If your service provider does not allow access to FTP directly, there are some systems that will perform the FTP session on your behalf. These systems are called "ftp mail servers". These allow the user to request files to be retrieved by electronically mailing a message to the server. To use the service, you must first learn how the service works. This is done by mailing the server address with the word "help" in the body of the message This will result in the directions being sent in a message to you. Then, following the directions, you can request files from any FTP sites through the server. The server will send both the retrieved files and a message detailing the execution of your request. Here is a sample request message: To: ftpmail@decwrl.dec.com Subject: Body: connect ccnga.uwaterloo.ca anonymous brain@msen.com chdir /pub/cbm/comp.sys.cbm ls -l quit Please note the following: This service is only for retrieving files. Binary files will usually be uuencoded. They must be decoded before use. Large files may be split into smaller pieces. The resulting pieces must be editted back into one piece, and decoded if necessary. Potential ftpmail servers include: ftpmail@decwrl.dec.com bitftp@pucc.princeton.edu + ftpmail@ftp.sunset.se + ftpmail@census.gov Craig Bruce has set up a ftp mail server off his regular email address. Here is how you would utilize it: To: csbruce@little.uwaterloo.ca Subject: ftpmail Body: help bcode ftp ccnga.uwaterloo.ca cd /pub/cbm/os/ace dir get ace12.doc quit All of the regular FTP commands are supported, with the addition of the following commands: help - gives help information. bcode - requests the data be sent as bcoded files. hexcode - requests the data be sent as hexcoded files. + replyto - gives email address to reply to for broken email clients. + maxlines n - Returns files in messages of at most n lines. 6.9.3. How do I send files to an FTP site? If you have the Commodore 128 .sfx creator, use it. It is part of the CS-DOS public-domain software package, and it requires a Commodore-1700-compatible RAM expansion unit. If you can't make .sfx archives, upload the files as straight binaries. Text files which you include in .sfx archives should be PETSCII. Separate text files should be ASCII or ISO 8859-1. If you are uploading GEOS files, use William Coleman's Convert 2.5 program to transfer the files to standard Commodore format before including them in the .sfx archive. You can make .sfx archives on a Unix machine by first compressing the files into an .lzh or .lha archive, then using Marko Makela's LZHconvert package on the LHarchive. This technique may work on some non-Unix computers. LZHconvert is on ftp.funet.fi in directory /pub/cbm/archiving. Upload a .readme file separately from your program or archive. In your readme file, give a one-sentence description of each of your program(s). List the lengths, starting addresses, and CRC32s of the files. Look on ftp.funet.fi in /pub/cbm/archiving for CRC-32 software. People should be able to make sure easily that they have all the parts of your software package. Put a complete file list in the readme file. Make a directory on the FTP site if you can, and put all your files in that. E-mail the maintainers right before you post your data. Your message can be just the .readme file with an introductory comment. The following is a list of valid FTP sites as of 26 Sep 1995. In the directory names below, replace "..." with the existing name closest to the purpose of your files. "Dir" indicates whether the FTP site allows you to create your own directories.

Internet Raley Chat (IRC) is an online version of citizen's band radio or BBS chat rooms. The service is worldwide and is available on the Internet. To use IRC, one would normally use a client program (typically called irc on UNIX machines) to access the service. Although the program used to access IRC varies, the commands are pretty much standard. All commands are entered on the text line and begin with a "/" character. Here are a few important ones: /join #c-64 Join the #c-64 channel, which discusses topics concerning Commodore hardware and software. /msg Commbot help will get you info on Commbot which carries C64/128 software to download. /msg Filebot help another C64 bot with software to download from. /msg coolhand xdcc list if he is online, this user has many c64 files which can be downloaded via this command. /quit leave. /names * List names of all people in current channel. /dcc send (nickname) (filename) Send a file to person (nickname). /dcc receive (nickname) or /dcc get (filename) REceive a file from someone. If you need more info on how IRC works, there is a file available on Jim Brain's email file server called irc-info.txt that explains IRC in more depth. (See Section 6.5.2 for directions on how to use the mail server) 6.11. What else is available online? If you are looking for other places on the Internet to talk Commodore, there is the Commodore forum on CoSy, a system accessible from the Internet. To access this service, you must have access to a telnet program. Here is the relevant information: telnet cosy.softwaords.bc.ca login: cosy CoSy: j commodore This will bring up a list of topics pertaining to Commodore. The forum moderator is Robert Todd and his email address is robert.todd@bbs.serve.org. This forum is ideally suited to discussions about the Color64 BBS system and other Commodore BBS systems. If you wish to post in the forum, please send email to that effect to Robert Todd. --------------------------------------------------------------------------- Table of Contents (for this file) --------------------------------- 7.

Exchanging Data At some point in time it becomes necessary to move data from one machine to another. Sometimes this is easy, sometimes it is not. This section will | help you decide which way of transferring files is best. For those who have + WWW access, additional information is at + http://www.funet.fi/pub/cbm/transfer/ + and also at: + http://hem.passagen.se/bacchus/tools2.htm 7.1. How do I exchange data among Commodore 8-bit machines? You can exchange data between Commodore machines in a number of ways, but each way requires an exchange medium, whether it be tape, disk, modem, or null modem. To transfer files between any Commodore machines besides the Plus/4 series that have datasette ports, the file can be save to tape and exchanged. The Plus/4 series tape drives read and write data in a format not compantible with any other CBM system. To transfer files between any Commodore computers with disk drives, you need to find a drive that can be connected to either computer, or two drives with compatible disk formats. Some examples of two drive setups: 2031 1541 4040 1541 (Read but not write compatible_ 8050 8250 (can't use back side of 8250 disk) 8050 SFD1001 (can't use back side of SFD1001 disk) 1551 1541 1571 1541 (can't use back of 1571 disk) Modems can be used to exchange the information, if both computers can use modems. Just perform a dowload on one end, and an upload on the other. Null modems can make this job simpler, by removing the data-> telephone line step performed in a modem. With all of these methods, data files should transmit fine, but program file written in ML will most likely not work, and BASIC programs will usually fail is loaded on a machine with a differing version of BASIC. 7.2. How do I exchange data between an IBM(tm) and my Commodore? + Commodore computers use a disk format that is not compatible with MS-DOS + style machines. However, there are two ways around this. One is to use + a 1571 or 1581 drive (which can read and write IBM-style disks) with a + special program to transfer files. The otehr is to connect a CBM drive to + the IBM. There are multiple options for each way you choose. Note that + the 1541 cannot read or write MS-DOS disks without some hardware + modifications. Most of the programs run in either 64 or 128 mode, although + there are a few CP/M MS-DOS utilities available that work in C128 CP/M + mode. Big Blue Reader + Big Blue Reader + SOGWAP Software (Author) + CMD (Distributor). + Platform: 64/128 A commercial package, The Big Blue Reader, from SOGWAP software, runs on either a 64 or a 128, will read and write MS-DOS format 3.5" (with a 1581) and 5.25" (with a 1571) disks.

RUN Reader + RUN Reader + Platform: 64/128 + RUN (Author) + CMD (Distributor) RUN magazine (4/89 to 6/89) published a series of programs that would use 1571/1581 drives to transfer MS-DOS files to and from a C= drive. It is also limited in file size handling ~43-44K. Little Red Reader + Little Red Reader + Platform: 128 + Craig Bruce (Author) + csbruce@ccnga.uwaterloo.ca (Internet Contact) Issues 4 and 5 of C= Hacking magazine presented a program called Little Red Reader for the 128 that will copy files to and from MS-DOS floppy disks. The menu-driven program requires two disk drives to work, where the one containing the MS-DOS disk must be a 1571 or 1581 (or compatible). The program does not buffer data internally, so the only size restriction on copying is the capacity of the target disk. The program provides PETSCII/ ASCII conversion but will work only with the root directories of MS-DOS disks. The program is also available via FTP and is FREE. 1541-dos + 1541-dos + Platform: 64/128 + ftp://ftp.funet.fi/pub/cbm/documents/1541-dos (WWW URL) To read and write to MS-DOS disks with 1541 disk drives you have to make a small hardware modification. The 1541-dos package contains instructions on how to modify Commodore 1541 and Oceanic OC-118/OC-118N disk drives, and programs to read disks in MS-DOS format and to write to disks in a format that can be read by MS-DOS computers. x1541 + x1541 (1.0) + Platform: IBM + Leopoldo Ghielmetti (Author) + Leopoldo.Ghielmetti@epfl.ch (Internet Contact) + ftp://ccnga.uwaterloo.ca/pub/cbm/ (WWW URL) + This father of all transfer programs first made use of the cable now + referred to as the X1541 cable.

All you need is a simple cable between user port of C64 and PC's parallel printer port (LPT). Loading of a 50 KB program takes about 3.0 seconds and transferring the same program from C64 to PC takes 4.5 seconds. (Times were measured on a PAL-C64 and 486DX-40, NTSC units will see slighly faster times) This program is a boon for every C64 user that has only a cassette drive, as the loader program needed fori the C64 is shorter than most cassette turbos and aboyt 45 times faster. C64-Connect stores C64 programs on PC in the standard PRG format, so you can easily convert them to various file formats used by emulators.

TransNib + TransNib (1.00) + Platform: Amiga and 64/128 + ftp://ftp.wustl.edu/systems/amiga/aminet/misc/emu/TransNib100.lha The TransNib 1.00 package for Amiga allows transferring files C64<->Amiga at up to 60000 bps. It uses a parallel<->user port cable that currently transfers 4bits at a time. Uses 2-way handshaking. 2 versions of the 64software are in the archive. Requires a disk drive. 1541 fastloader compatible. The Amiga side software can be run from shell of WB, multitasks fine and has nice simple GUI.

It's about 25 times faster than a null modem cable, and it even leaves your Amiga serial port free for other applications. You can transfer up to 255 files in both directions in multitransfer mode. The program works with an cable attached between the 64 user port and the Amiga parallel port.

How do I exchange data between a Macintosh(tm) and my Commodore? + I have one report of someone working on this. 7.5. How do I exchange data between an Atari ST(tm) and my Commodore? Atari ST can read and write 3.5" DD disks formatted for PC. You need to use TOS 1.4 or higher to format. Using Big Blue Reader to write 3.5" PC format on CBM will permit transfer. ST also has RS-232 port, so one can transfer data by using RS-232 adaptor on the C64 and some terminal/handshaking programs to control the transfer. 7.6. How do I exchange data between a UNIX(tm) machine and my Commodore? One way is to use PC and then ftp to UNIX, unless the UNIX runs on a PC. Some Sparctations have drives with MSDOS filesystem emulation, but it has problems even with Atari/DOS disks. cbmfs cbmfs is a read-only filesystem driver which allows transparent reading of 1581 disks under Linux. It is installed as a loadable kernel module and allows mounting Commodore 1581 disks in a standard 3.5" floppy drive, and 1541 disk images (.D64 files) copied to any floppy disk. PETSCII to ASCII conversion can be automatically performed. Partitions on 1581 disks are accessed as subdirectories. The publically-released version will be available at and at . prlink + prlink + Platform: UNIX and 64/128 + Olaf Seibert and Marko Makela (Authors) | ftp://pub/cbm/transfer/CBM-to-PC/prlink-0.9.5a.tar.gz (WWW URL to Source) | prlink is a program that uses the a parallel port to C64 User port cable | to transfer data from the Commodore to Linux (or any UNIX). 7.7. Are there other ways to exchange data between computers? If you are transferring data to another computer (e.g. a PC) in the same room, or if you are lucky enough to have a terminal server line near your 64/128(more and more colleges are putting such beasts in dorm rooms), you be able to connect your serial port directly to another computer. If you have a terminal server port, all you need is a C= RS232 to standard RS232 adapter (see 9.8). If you are connecting to another, PC, you will also need a null modem. A null modem is a simple device that you can buy for less than $10. It typically is a small box with a 25-pin (or 9-pin) RS232 connector on either side. Put it somewhere in the line between your C= and the other PC. 8. Operating Systems Most Commodore users aren't aware that each machine has an operating system. Since all Commodore systems come complete with a built in operating system and BASIC programming language, the need for an operating system is minimized. However, Commodore's internal OS is not always the right tool for the job, so alternate OS systems are available for the CBM. 8.1. What Operating Systems are available? Well, Commodore computers come with a standard operating system built in ROM. They also contain a built in BASIC interpreter which is normally activated after switching on or resetting the computer. If you want alternative options to replace the existing OS, there are a few that may suit your needs. GEOS is the best known, but a number of people have made UNIX-like operating system replacements for the Commodore 64 and 128. Also, on the 128, CP/M is available out-of-the-box. (see below for details on different OS types.) 8.2. What is GEOS? GEOS stands for Graphical Environment Operating System. It is a Graphical User Interface (GUI) style of OS, and it brings to the Commodore 64 and 128 integrated applications. The graphical nature of GEOS allows applications to use fonts of any size, bitmaps, and menus and mice. The system was Designed by Berkeley Softworks, now GEOWorks, and is supported now by CMD. There are a number of graphical style GEOS applications, like GEOWrite, GEOPaint, GEOPublish, GEOTerm, etc. The system is very easy to use, and is very fast, even when compared to other GUIs like Windows and OS/2. GEOS can make very effective use of a Ram Expansion Unit, a RAMDrive or RAMLink, or GEORam. GEOS allows you to configure your REU to appear just like another (very fast) disk drive, although it does not keep its contents when you turn your computer off. So, any GEOS software that works off of a disk will work out of your REU. Since GEOS is very disk-intensive, this greatly improves the performance of your system. Indeed, some firm GEOS adherents have said that they would not use GEOS without a RAM device of some sort. GEOS will not work with a stock 1700. To have a RAM drive, in GEOS, you must have at least 256K of expansion. Thanks to patches developed by Jim Collette(configure2.1), GEOS also supports 1 Meg, 1.5 Meg, and 2 Meg REUs. GEOS files are structured differently from standard Commodore files. They cannot be uploaded or downloaded directly. Before you upload a GEOS file, use the freeware GEOS application convert2.5 by W.C. Coleman to convert it to Commodore format. When you download a GEOS file, you must use the same program to convert it to GEOS format. By convention, GEOS format files converted to standard Commodore format have a .cvt on the end; however, many converted GEOS files just have the same name as the original GEOS file. As a rule of thumb, any GEOS file you download, regardless of the extension, must be converted to GEOS format with convert2.5. If you download an archive of GEOS files (e.g. a .arc or .sda file containing GEOS files), you must first dissolve the archive using your C64 or C128 in native mode. The constituents of the archive will be converted GEOS files, whether or not they have the .cvt extension. Each of these constituents (which are GEOS files) must be individually converted to GEOS format with convert2.5. If you need some help with GEOS or any aspect of it, I refer you to Myles Skinner at mskinner@julian.uwo.ca. He is one of many people who use GEOS every day and can be of help. 8.3. What is UNIX? UNIX is an OS that was developed by Bell Laboratories in the 1960's and is now used on many workstations. It is a multi-user, multi-process OS that has extensive support from the educational and commercial communities. Internet and Usenet are primarily a collection of UNIX workstations networked together. The UNIX-like OS replacements for Commodore computers mainly emulate the shell of UNIX, where programs are run by merely typing in their name. Other aspects of UNIX, such as multiple processes are supported by some of the offering, which are: Asterix. - A UNIX-Look-and-feel Shell replacement for 64 UNIX128. - A small implementation of UNIX for the 128. ACE 128/64.- A new offering which borrows the UNIX shell look for 64 | and 128. It is available at: ftp://ccnga.uwaterloo.ca/pub/cbm/os/ace/ + LUnix - A new offering which attempts an implementation of UNIX + for the 64. It is available at: | ftp://rpool1.rus.uni-stuttgart.de/~etk10217/proj.htm + CS/A65 - Andre Fachat's multitasking OS. At: + http://www.tu-chemnitz.de/~fachat/csa/ + CXII - http://www.cynapses.com/ry/cx2home.html 8.4. What is CP/M CP/M stands for Control Program for Microcomputers and is available on every Commodore 128. There is also a CP/M cartridge available for the Commodore 64, but it cannot read CP/M disks, just 1541 formatted disks, and there are questions concerning its ability to work with all revisions of the Commodore 64. CP/M was very popular in the early eighties before MS-DOS became popular. It requires a Z-80 microprocessor, which the 128 has, or an 8080 processor, and a disk drive capable of reading CP/M disks, such as the 1571. If you don't need to read existing CP/M formatted disks, then a 1541 could also be used. This operating system is the one that MS-DOS was modeled after, so there are a lot of similarities. If you are interested in using CP/M as your primary OS, then please check out the newsgroup comp.os.cpm, as they have more info on the current events concerning CP/M. The version of CP/M used on the 128 is 3.0, commonly called CP/M Plus. It is compatible with earlier versions of CP/M but adds some new features. The copy of CP/M 3.0 that ships with the 128 was specially modified to allow use of the features of the 128, such as the Ram Expansion Unit as a RAM disk, the SID chip, and the extra RAM of the 128. In the March 1994 issue of dieHard, Mike Gordillo gave an overview of the CP/M operating system. It is one of many such articles that should be read by anyone new to CP/M. 9. Demonstrations Very few Commodore enthusiasts have never seen a demonstration, yet many aren't really sure what one is. Well, since these programs are still alive and strong in the 1990's, we need to answer some of their mysteries (but not all of them, as their job is to amaze). 9.1. Just what is a demonstration, or demo? A demonstration, or "demo" as they are known, is a piece of software that is designed to provoke a visually and aurally pleasing effect from the computer. This usually involves large amounts of multi-colored graphics, complex synthesized or digitized sounds, and orchestrated movement of shapes or color schemes on the screen. Demos originated as introductions to "cracked" games, games in which the copy protection had been rendered useless. As time wore on, the standard abilities of the computer were all used in demos, and rival "cracker" teams raced to bring out the best demo. In the search for the "best demo", demo authors, or "coders", tried to maximize the use of the computer in a demo program. Also, they exploited any undocumanted feature the computer could provide. Since most of the circuits in the Commodore computers were multi-purpose, experienced coders could use some of their features in non-standard ways. Some examples: Removing the top and bottom border. Removing the side borders. Placing text (text mapped sprites) in the open borders. More than 8 sprites on screen at once. pseudo interlacing to create illusion of up to 640*400 resolution. Since the commercial game market has shrunk significantly over the past few years, and since demos are sometimes too involved to be classified as a game into, many demos are packaged so they can "stand-on-their-own". Users can download a demo, load it up, and run it like any other program. As demos got more involved, some coders produced cutting-edge technology demos intended to "one-up" their rival coders, while others made artistic, but less technically challenging demos for arts sake. Either way, it is important to note that demos are not usually interactive. They are meant to be viewed and listened to. Demos are mostly passive entertainment, and appreciation for the effects generated in a demo increases as one realizes the normal limitations of the Commodore line of computers. So, sit back, load up a demo, run it, and enjoy. 9.2. What does NTSC and PAL mean? These two acronyms refer to the type of TV broadcasting signals used to create the video picture on your TV or monitor. American, Japanese, and Canadians use NTSC, while a good part of Europe uses PAL. This usually makes no difference to programs, as the C64 and C128 in C64 mode always present 200 lines of pixels to the video display. However, since the PAL standard allows more lines to be displayed on the screen and has a slower screen refresh time, the PAL computer has more time before screen refreshes to perform other operations, and also can put more information on the screen in some cases, since there are more lines in a PAL dislpay. Since demos use highly optimized timing and complex routines to perform the effects, some demos can only be written for PAL machines. Sometimes, a demo is written for a PAL machine, but it can be made to run on an NTSC machine. Demos that can run on both machines without any code modification are called regular demos, those that can only run on PAL machines are PAL demos, PAL demos that have been modified to run on NTSC machines are called NTSC-fixed demos, and NTSC demos that have been modified to run on PAL machines (rare) are called PAL-fixed demos. The mean difference between NTSC and PAL is that the mathematical description of NTSC will fit on one page while PAL takes a phone-book style book full of integral/Fourier/Laplace equations. From a demo coder's point of view, the difference lies in how many cycles you get per scan line and how many scanlines there are: VIC type cycles per line lines per screen frame rate old NTSC-M 64 262 60 Hz new NTSC-M 65 263 60 Hz all PAL-B 63 312 50 Hz 9.3. Where do I get demos? There is a whole site full of demos. They are located in the /pub/cbm/c64/demos directory of nic.funet.fi. See section 5.4 for directions on how to transfer files from this site. 9.4. What is a demo competition? This is a "convention" where people from the demo "scene" get together. They are usually held in Europe, although other countries do have them. Coders get together and exhibit previously unreleased demos in a competition where the best ones are ranked according to a subjective scoring system. At the end of the competition, the demos are released to the public. To make things somewhat fair, demos are judged according to computer type, so Amiga demos do not get judged alongside 64 demos. These competitions are usually held in conjunction with music or art competitions. Most demo competitions are held within Europe due to copyright laws and stuff. Previous pardies (demos parties, or competitions) held were:- Event Location Date ----- -------- ---- Radwar Pardy Germany January 1994 Pardy III Denmark Decemeber 1993 Chormance & Faces Pardy Hungary December 1993 Elysium Pardy Poland Decemeber 1993 Entropy Pardy Holland June 1993 Assembley '93 Pardy Finland May 1993 The Computer Crossroads Sweden April 1993 Radwar Pardy Germany January 1993 Duration 1993-1994 (March 1994) Most pardies are held when all the schools are on hoildays. The point of a copy pardy is to go there with your computer, meet other computer friends from other groups and swap different warez, meet other members of your group and using the combined skills from the members (graphics/coding/musix/spreading), write a demo before the closing time for the pardy so it can get voted on. The winner comes away with about 300 Kronar or similar. 9.5 What does FLI, DYCP, etc. mean? Writing a successful demo often means tweaking routines and hardware to reach beyond the normal capabilities of a computer system. Such is partially why such programs are called "demos". To tweak the system and hardware, programmers utilize undefined routines, use hardware in non- standard ways, and create tming loops that force events to happen at certain intervals. When these components are composed together, they create an effect, either via video or sound. The effect is known by a name or phrase. Some phrases are known by their acronyms, as the two in | the heading are known. FLI is Flexible Line Interlace, while DYCP | is Differential Y Character Position. It is beyond the scope of the FAQ to discuss all the effect names, but a somewhat complete list can be found at http://www.msen.com/~brain/pub/demo-acronyms.txt on WWW or as file demo-acronyms.txt on Jim Brain's MAILSERV server (See Section for more information on mailservers.) --------------------------------------------------------------------------- Table of Contents (for this file) --------------------------------- 10.

Emulators As time moves on, people move to other computer systems, for business resons or otherwise. However, many still long to play Commodore games, use Commodore software, and enjoy Commodore demos. Thus, emulators were born to bring the non-Commodore computer owner the enjoyment of owning a Commodore. 10.1. What is an emulator? An emulator is a piece of software that runs on a given platform and emulates, or mimics, the operation of another machine. When the emulator loads up a program, the programs runs as though it were running on the emulated platform. | For more information on emulators and their use, please see The Commodore | emulator FAQ, maintained by Ken Gifford (tsrken@voicenet.com). It | can also be found on Jim Brain's MAILSERV server (See Section 6.5.2 for more | information). For those with WWW browsers, the CBM Emulation FAQ is at: | http://www.hut.fi/~msmakela/cbm/faq/ 10.2. What platforms do 64 emulators exist on? 64 emulators exist on the following machines: Amiga IBM Atari ST Macintosh UNIX 10.3. What platforms do 128 emulators exist on? There is a very basic Commodore 128 emulator bundled available for the UNIX platform under X. It is bundled with X64. 10.4. Are any other Commodore computers emulated? There is a commodore product called the PET emulator that remaps a Commodore 64 to emulate a PET 40 column unit (i.e. PET 4032). You can run this program on a C64 to emulate a PET, or you can run this program | on a 64 emulator to emulate a PET on an IBM, for example. + As for VIC-20 emulators, one exists for the Amiga, and there is a program + similar to the PET Emulator that allows a C64 to emulate a VIC-20.

Troubleshooting 11.1. What do I do for my ill disk drive? If the drive spins and the LEDs are off: At the back of the 1541 circuit board are two bridge rectifiers - stout epoxy packages with 4 leads each. The innermost one is defective If both LEDs are dim: The 5VDC regulator is bad. If both LEDS are on: Drive did not make it through the power-on reset sequence. Kernal ROM (901229-05) is susepct, as is (in order of expectation): VIA (6522), CPU (6502), RAM (6116 or equivalent), or a "glue" chip in the reset logic If your drive won't even accept input from the computer, and the drive light is making some blinking pattern, then the drive may be telling you what is wrong. No Blink Kernal (E000-FFFF) ROM or 6522 VIA Failure One Blink 6116 RAM Failure Two Blinks Possible Zero Page RAM Failure Three Blinks DOS (C000-CFFF) ROM Failure Four Blinks DOS (C000-CFFF) ROM Failure Five Blinks 6116 RAM Failure Six Blinks 6116 RAM Failure | Six Blinks 2114 RAM Failure at c4 or c5 (8050) Seven Blinks 6116 RAM Failure Eight Blinks 6116 RAM Failure 1541 The most common problem facing the 1541 disk drive is alignment. If your 1541 has trouble reading commercial disks, or reading disks written some time ago, but has less trouble reading recently written disks, chances are that your 1541 is out of alignment. C= service centers will typically align a 1541 for anywhere from $20 to $45. There are also 1541 alignment programs, (e.g. Free Spirit's "1541/71 Alignment System") which allow you to align a 1541 yourself. There are those who claim that this does not produce good results, but there are others who claim to have had satisfactory results with these programs. There were a couple of articles in COMPUTE Gazette and I think RUN on how to do this. The real problem is mechanical in nature and can be over come. Other products are PHYSICAL EXAM 1541 and 1571 versions. + All but the very earliest 1541 units can accomodate either a 1541 ALPS + mechanism or a newer Newtronics mechanism. Keep that in mind when + swammping mechanisms. 1571 The C=1571 drive is normally a double sided drive. However, it can also emulate a 1541 and read single sided disks. Some of the earlier 1571's had older system chips (ROMs) which caused a couple of problems. One, these older drives were typically very slow when writing to the back side of a disk. Two, it would take these drives ~30 seconds to go into single sided mode. To check your ROM version, read the error channel of the disk drive right after startup. On the 128, just PRINT DS$. On the 64, use: 10 open15,8,15:input#15,a,a$,b,c:close15:printa,a$,b,c | Run the program; if the message says v3.1, you have the newer ROM. | If it has a version 3.0 or older, you have the older ROM. One problem that might occur is not having the head close enough to the disk as required because of the light tension of the spring that pulls the head down. Somewhere I remember that there was supposed to be a replacement part. However, one of the alignment programs suggesting using pennies to weight it down and lo and behold it started working. 1581 The C=1581 drive is a 3.5" drive that uses DSDD 800K disks. It is compatible with both the C64 and C128, although some programs will not work correctly with the 1581. A small number of 1581's were shipped with an early version of a controller chip which has problems with some software. 11.2. What do I do for my ill computer? At times, every computer must be serviced. As the parts supply of Commodore equipment dwindles, servicing becomes harder. However, there are many sources in Section 16.2 that can service your Commodore machine, and here are some things you can do to service it yourself. If the screen is garbled, but BASIC seems to be limping along, and any command is met by an error, RAM could be bad. You can look at bit patterns on the screen by determining screen codes for garbage characters. only bit 4 (32) should be on. After you determine which bits, here is the bit->IC mapping: Bit 7 (128) : U12 Bit 6 (64) : U24 Bit 5 (32) : U11 Bit 4 (16) : U23 Bit 3 (8) : U10 Bit 2 (4) : U22 Bit 1 (2) : U9 Bit 0 (1) : U21 A common problem with the C-64 is it's power supply. The C64 power supplies are not especially powerful, and have this disturbing tendency to fail. If your computer stops working, first check the power supply. Replacement power supplies can be obtained from a number of mail order places (e.g. Tenex, Parsec, Inc.). Additionally, several places advertise "heavy-duty" power supplies that come with warranties, and give the C64 enough power to run a REU. If your power supply goes, it can sometimes take other parts of the computer with it. If your power supply has died, but the C64 continues to fail with a known working power supply, it is likely that a few of your chips got fried. Also, another common problem with the C64 is the fuse inside the computer. If the system power on light comes on, but you get a blank screen, suspect the fuse. It is usually blown by misinsertion of devices into the computer. + According to the official Commodore Diagnostician II Reference Chart + released September 1989: + " intermittent blank screen or graphics " are caused by: + Bad power supply + Failed 6510 Microprocessor Chip + Failed 6567 VIC NTSC (6569 PAL) Chip + Failed 82s100 Programmable Logic Array Chip (PLA) + Failed 901226 Basic ROM Chip + Failed 4164 Memory RAM + The PLA chip is 40% responsible for all full screen failures. 11.2.2. What do I do for my ill Commodore 128? Like the 1571, the C-128 has an older ROM and a newer ROM. The differences between the two are less serious than is the case with a 1571. The easiest way to tell the difference is to click down the CAPS LOCK key and hit Q while in BASIC direct mode. If you see a lower case q, then you have an older ROM. If you see an upper case Q, then you have a newer ROM. New ROMs | can be ordered from (e.g. Paxtron Corporation) for about $25. The ROM | chips in the 128 are all socketed, so replacing the chips is relatively | easy. 11.3. What do I do for my ill keyboard? Clean it: Materials you will need: Denatured (rubbing) alcohol, a clean pencil eraser, cotton swabs, a small Phillips head screwdriver, a jewellers size Phillips screwdriver, a solder iron of some type, and a Commodore 64 computer keyboard. Procedure: 1. FIRST AND FOREMOST. Make certain that you have discharged any static electricity in your body by grounding yourself to something like a cold water pipe. Otherwise, you could blow chips in your computer if you were to touch the wrong things. 2. Turn off your computer and unplug any and all cords and connectors, fast-loaders, modems, etc. (just have yourself a naked (if you will excuse the expression) computer). 3. Thoroughly clean all external connectors and ports with the swabs and alcohol. Also, clean all plugs that go into those ports. If the problem you had persists, proceed with the following: 4. On a clean surface, turn your key-board upside-down. Remove the screws in the bottom. 5. CAREFULLY, separate the two halves about an inch. Unplug the connector to the "power" LED on the top of the C-64. 6. Place the two halves flat so that the keyboard is facing you. The two halves will be connected by a wire harness. This harness may be held down by tape that must be removed in order to place the unit flat. 7. Remove the 15 or so brass screws that hold the circuit board under the keyboard. 7a.Unsolder the wires going to the shift-lock key. 8. Turn the circuit board over. You will see the bottom of the keyboard with a rubber "U" under each key, which makes contact with the board. You will also see on the circuit board, a pair of gold contacts for each key on the C-64. 9. CAREFULLY wash ALL the rubber "U"'s and the gold contacts with the swabs and rubbing alcohol. Allow the alcohol to DRY. 10.Gently, clean each gold contact with the eraser. BRUSH AWAY THE ERASER CRUMBS (I use a small hand-held, battery-powered vacuum cleaner). 11.Re-clean the gold contacts with the swabs and alcohol to ensure that you have removed ALL traces of the eraser. 12.Reassemble the C-64 in the reverse order of disassembly. 12. Modifications and Cabling As time wears on, many Commodore owners are turning to themselves to manufacture small interfaces, modify their systems, and perform other enhancements. Here are some common things the user can construct himself or herself. 12.1. How can you alter which side a 1571 reads from? On a 128, you can force the 1571 to go into single sided mode with the drive command "u0>m0". (Issue such a command with open15,8,15,"u0>m0":close15.) On the 64, a 1571 defaults to single sided mode, but you can convert it to double sided mode (and read full double sided disk in 64 mode) with the drive command "u0>m1". While in single sided mode, you can actually format both sides of the disk as separate file systems. The command "u0>h0" selects the regular side of the disk, and "u0>h1" selects the flip side of the disk. Note that the flip side, when formatted this way, cannot be read by a 1541; neither side will be readable by a 1571 when the disk is inserted upside-down. 12.2. How do I open a C128 power supply? First, unplug both leads running from the power supply and turn it upside down. Locate four (4) small circles in the bottom; two are in the corners and two in the other end a bit nearer each other. Find some sharp tool, e.g. pin or nail. In turn, poke it inside each of the cirles, firmly, and pull the caps off gently. They'll come out easily. Breaking the caps should not matter, but there is no need to destroy the casing in process. Unsrew the 4 Phillips headed srews with an appropriate tool. Notes: This does not apply to the C64 brick! Some 128 power supplies do not have rubber feet; rather, they have "L"- shaped extensions on the casing. The caps on these extensions are not made of rubber, but can be removed. 12.3. How do I make a cable to hook my CBM 1902A to my 64 or 128? Here is the diagram used to make a replacement Chroma / Luminence 40 column cable, that the 1902A uses, to connect to the 64 or 128. _______ ________ / 3 \ 1. Not Used / 2 \ *1. Luminance / 2 4 \ *2.

How do I build a 2400/9600 bps RS-232 interface cable? A new programming technique makes it possible to acheive 9600 bps on an | unexpanded Commodore 64 without the use of a Swiftlink cartridge. Daniel Dallmann of Germany is the originator of this technique and is currently writing modem drivers for some of the popular C64 terminal emulation programs to take advantage of this new technique. The interface described below is a little more complex than the one in Section 12.4, but has many advantages: * The interface generates proper EIA232 (RS-232) voltage levels. The one in Section 12.4 relies on the ability of most newer RS232 equipment to handle lower voltages. * The following interface can be used as a direct replacement for the | interface in Section 12.4, and will work will all most telecommunications programs at up to 2400 bps, while providing the necessary interfacing to allow suitably equipped applications to | operate at up to 9600 bps. (Some programs needing DCD and DTR lines | may have problems.) * if you currently own a normal RS232 interface, that interface can be modified to incorporate the new interfacing for 9600 bps operation. (in some cases one line of the old interface has to be disconnected, see note **1 ) 9600 bps is the maximum limit this type of technique due to the timing limitations of the C64. The delay between the activation of the NMI-handler and the falling edge of rxd is too long. The handler must be called in less than 100 cycles. That's no problem at 9600 bps, but for 19200 baud (the next higher baud rate), you have only 50 cycles, and that's impossoble (because of VIC-DMA ). On a C128 in fast mode 38400 baud may be possible, but I don't have a C128, so someone else has to try it out.

Because of the new wiring DSR will seem to be active to all 'old' programs, so that there won't be any troubles.

How can I determine how much VDC video memory is in my C128?

How can I convert my C64 to run on battery power? The July, 1990 issue of 73 Amateur Radio has an article on converting the C64 and 1541 to run on DC power. I'll summarize the C64 portion: DC Power Conversion for the C64 1. Locate component CR4 on the circuit board. Mark the positive hole on the board. Desolder and remove the component. 2. Rest :-) 3. Connect the marked hole to +12V. 4. Desolder and remove VR1. Looking down at the component side of the board, connect a wire from the vacant right hand hole and run it to +12V. 5. Locate L5. It will probably be in one of two locations. On the older version, desolder the right hand leg and lift. On the newer version, desolder the top leg and lift. 6. Connect +5V to the empty L5 hole. 7. Locate the R37 and R100 pads. Use a continuity meter to find the pads that are connected. Desolder and lift these legs. You will insert a 60 Hz clock here. 8. You could generate this clock using a variety of methods. Here's one: +12V __________________________| | | | C1 R1 ______|_______ |-)|-+-/\/\/-+-----|6 8 | | | \ | | | XTAL1 / R2 | MM5369 | | | \ | | |-)|-+-------+-----|5 1|---> 60 Hz (to R37 pad) C2 | 2 | --------------- | GND C1 = 30 pF C2 = 3-15 pF (variable) XTAL1 = 3.57 MHz crystal R1 = 1k R2 = 10M It is suggested that you use a short length of shielded coax cable to connect the 60 Hz output to the R37/R100 pad. Also, it is suggested that you use a frequency counter to tune the above circuit to exactly 60 Hz. This conversion would work well if you wanted to use the C64 in a car or powered by a solar set-up. 12.7. How do I build a GEOCable interface?

Enhancements If you like to tinker with your Commodore to get the best possible performance out of it, these suggestions and products may help you in your quest. 13.1. How do I increase my disk drive's transfer speed? Since the introduction of the Commodore VIC-20 and the slow serial bus, Commodore owners have been plagued by slow disk access. There are two ways to allevaiet this problem, fastloaders and ROM replacements. 13.1.1. What is a Fastloader? The Commodore 1541 drive and any drive attached to a VIC-20, C64, Plus 4, C116, or C16 suffer from very slow read and write times. This is caused by Commodore's haste in "economizing" the IEEE-488 bus used in the PET series of Commodore computers into the serial bus. The IEEE-488 bus transferred 8 bits of data at a time, and performed some synchronization steps, or handshaking, between bytes. Commodore reduced the path to 1 bit but kept most of the original handshaking, most of which is redundant when transferring 1 bit at a time. Early on, some developers noted that, since the 1541 drive was intelligent enough to execute a program loaded into its RAM, and the Commodore operating system calls to do disk I/O could be bypassed, they could write software that sped up the loading process by modifying or completely changing the protocol used on the serial bus. This is the idea behind fastload cartridges like FastLoad, Mach 5, etc... 13.1.2. What is a ROM replacement? As programs became more complex, some programs would not operate with this approach. Thus, the developers then rewrote parts of the Commodore operating system on both the computer and the disk drive, and replaced the parts of them that did disk I/O with new pieces of code. This is the idea behind JiffyDos and others. The basic idea in speeding up the disk drive is to use more than 1 line to transfer data, effectively doubling the transfer speed. Then, reduce synchronization requirements in the protocol to a bare minimum, as synchronizing time is time not being used to do transfers. The fastload cartridges are handicapped somewhat by the need to transfer the portion of the program that runs in the disk drive to the drive using the slow speed evry time the drive is used. This can be alleviated somewhat, but the replacement operating system replacement products like JiffyDos win the race since they do not need to load code into the drive, as it is already there. 13.1.3. What are the disadvantages to using a drive enhancement? The products are not 100% compatible, as they sacrifice reliability for speed somewhat. That means that a program that does not load due to an error while using a fastload product will probably load without the fastloading enabled. Also, some programs can not handle the change in loading or reading speed, so these enhancements yield about 90% compatibility. 13.1.4. What other things can I do to speed up the drive? You can also increase the speed of disk drive operation by organizing consecutive parts of a file on disk to fall a certain number of disk sectors apart. This is called the interleave or interleaving factor. Normally, a 1541 disk drive space consecutive parts of a file 10 sectors apart, but you can change that a little to minimize the time needed to find consecutive parts of a file. Also, the C128 in 128 mode hooked up to a 1571 or 1581 has a built-in fastloading scheme called burst loading. Therefore, if you are in 128 mode and hooked up to a 1581 or a 1571, you already have this feature. However, the 128 in 64 mode reverts back to the old slow serial routines, and the 128 in any mode using a 1541 cannot use the burst load routines. 13.2. How do I expand my disk drive's capacity? Software Support International sells the 1541 RAMBoard, which will increase you 1541's memory. SSI used to market a similar board for the 1571, but they have depleted stock and no longer carry it. You can also expand your disk drives on board RAM capacity, and use that extra memory for better archiving performance. + 13.2.1. What is a Hard Drive? Who sells them? + A hard disk drive is a non-removable ramdom access medium similar that + allows one to store very large quantities of data. Hard disk drives + are mandatory on most newer computer systems, but are usually optional + for Commodore 8-bit computers. However, the faster load time, the + greater capacity, and the ease of use make them desirable. CMD sells hard drives for the Commodore 64 and 128. They range in sizes from 50 Megabytes on up. In comparison, a Commodore 1581 drive holds .8 Megabytes. + 13.2.2. What is 64NET? If you have access to an IBM of some kind (preferrably with a hard drive), you can use a product called 64NET to hook the drive up to the Commodore. 64NET consists of a cable which connects the CBM User Port and the IBM Parallel Port together, and a program that runs on both machines. The program on the IBM is a standard application, but the CBM part is a wedge, so it should integrate seamlessly with some programs. There is now just one copy of the product. Registered users simply receive a 64NET.KEY file that enables SAVING. There is a student discount of AUS$40.00. The product is at version 1.82.62 and has full OPEN/CLOSE/READ/READST support, can support 4 gigabyte IBM partitions, and have a built-in off-board monitor which includes some dos wedge functions. The IBM programs have link-based helpsystems and will run on any IBM machine. The registered version allows saving of files, wheras the PD version does not. The registered version also contains support for GEOS. The registered BETA version is available (with upgrade to final version free) for AUS$50.00, while the unregistered version is free. These prices do not include the cable that is required for operation. The cable, program, and more information can be received from Paul Gardner-Stephen at gardners@ist.flinders.edu.au. Also, the system can be ordered from: In Europe: Performance Peripherals Europe Germany +49 2227 3221 Michael Renz +49 2227 3221 And in Australia from: Russell Alphey +61 3 4278558 (A/H r.alphey@dce.vic.gov.au Paul Gardner-Stephen +61 8 277 7479 (A/H) Versions are available for the C64 and C128, and a C65 version is close to completion. + Also available is an Software Development Kit (SDK) with a CBM + cross assembler. + 13.2.3. What is SERVER64? SERVER64 is a product like 64NET, in that it allows you to use an IBM PC as a large hard drive. However, unlike 64NET, SERVER64 does not require a connection to the user port and a special boot program be run. Instead, the system uses an X1541 cable to attach the Commodore 64 serial port to an IBM parallel port. The product is available at: ftp://ccnga.uwaterloo.ca/pub/incoming/SERVER64.ZIP Documentation is available at: ftp://ccnga.uwaterloo.ca/pub/incoming/SERVER64.TXT Both are expected to move to the /pub/cbm/emulation directory soon. 13.3. How do I expand my computer's RAM capacity? 13.3.1. What is a Ram Expansion Unit? The original form of RAM expansion available to the C64 and C128 were the Commodore REUs (Ram Expansion Units). These REUs plug into the cartridge port, and provide 128K (the C=1700), 256K (the C=1764), or 512K (the C=1750) of additional RAM. This RAM is not true system RAM however; simply adding a 512K REU to your system does NOT mean that your word processor will suddenly be able to edit 512K larger documents. A REU will only be used by a program that was written to take advantage of an REU. As a caveat on this, you can use your REU as additional RAM for a RAMLink . An REU can be used as a Commodore Disk Drive by running the program RAMDOS. This will allow users to save and load files from the REU. If you are using CP/M, the REU can be configured to act like a disk drive under CP/M. Although the C=1764 was originally advertised for the C64, and the 1700 and 1750 for the C128, any of the three RAM expanders will work with either the C64 or the C128. Note that if you want to use any of them on the C64, you need a heavy duty power supply. The 1764 comes with such a power supply. There are hardware hacks that will expand a 1700 or a 1764 to 512K; additionally, a 512K REU can be expanded to 1 Meg or more. The plans are at ftp://ccnga.uwaterloo.ca/pub/cbm/hardware. While it appears completely safe to upgrade your REU to 1 Meg, there have been some reports of problems with REU's upgraded to 2 Megs. Sometimes the REU will work fine for a while, then fail. If you are upgrading your REU, it would probably be wise to stop at 1 Meg. If you are still memory hungry, consider a CMD RAMLink. If you don't wish to do it yourself, there are people who will do it for you, for a fee. The following individual will do RAM expansions on the 17xx series. He Has lots of experience doing these modifications. His current quoted price for expanding a 1750 from 512k to 1 meg is $60. Call for the latest prices. In addition he can do repairs on the RAM. Raymond Day 9601 Morton Taylor Road Belleville, MI 48111-1328 r.day@genie.geis.com (Contact) (313) 699-6727 On a similar note, Software Support International sells a device called the 1750 clone, which functions just like a 1750. It is not as expandable as the real 1750, but can be used where a 1750 is recommended or required. 13.3.2. What is a geoRAM Unit? When Commodore REUs became hard to find several years back, Berkeley Softworks introduced geoRAM, which is a 512K RAM expander. This RAM expander gives you all of the advantages of a 1750 with GEOS. However, it is not 1750 compatible, so it will not work like a 1750 outside of GEOS; it is transparent to other programs. (As a caveat on this, see the info on RAMLink)). DesTerm128 2.0 will not work with a geoRAM plugged in. A special version of GEOS 2.0 (which is bundled with geoRAM) is necessary to use geoRAM. No additional power supply is necessary to use geoRAM. The geoRAM can be upgraded to 2MB also. Contact Jens-Michael Gross at grossibr@buran.fb10.tu-berlin.de for information on upgrading the geoRAM. The geoRAM can be used without GEOS if it is installed in a RAMDrive or RAMLink. See Section 13.3.4 for information. 13.3.3. What is battery backed GeoRAM (BBGRam)? Battery Backed GeoRam is a products marketed by Performance Peripherals Incorporated. The unit is actually a geoRAM clone, but has battery backup included within the unit. The unit can be ordered in the following configurations: 512kBytes $92.97US 1MBytes $123.97US 2MBytes $165.97US 13.3.4. What is a RAMLink? RAMLink (RL) is a RAM expansion devices from CMD. The RAM in these devices can be partitioned into native mode partitions (with dynamically allocated subdirectories), or 1541, 1571, or 1581 emulating partitions. Thanks to the 15x1 emulating partitions, software does not have to be specifically written to run with a RL. The RL devices should appear as a disk drive to most programs. One notable exception is DesTerm v2.00, which does not work with the RL. There are few other exceptions, and no major commercial program has a problem running with an RL . The deciding factor seems to be whether or not the program uses a drive's internal ram. The RL does not 'mimic' having this type of internal drive ram, and if a program relies upon this it will not run. The heavily copy protected Digital Solutions' programs use this drive ram for its burst loading routines. So, even though a Maverick/RamBoard combination will write a copy of it to the RL, it will fail to boot. However, these programs, once booted from a 1571, will use and access all of RL's many functions for lightening fast loads and saves. RL has ts own power sources, separate from the computer. When you turn off the computer, the power to the RL is left on, leaving its contents intact. This power supply always remains on. (For safety from power outages, battery backups are also available.) RAMLink is a powerful, large device. It can be configured from 0 to up to 16 Megs of RAM, using industry standard 1x8 (100ns) 1 Meg and 4 Meg SIMMs.(1x9, and faster Simms can be used.) The RL is constructed so that the user may easily add additional SIMMs at any time. RAMLink has a port into which you can plug a Commodore REU or a geoRAM. You can configure RAMLink to either leave this RAM device alone, or to use the REU/geoRAM's RAM just as if it were part of the RAMLink's RAM. A RAMLink also has a pass-through port, in which you can plug a normal C64/C128 cartridge, and a parallel port for a CMD hard drive. The latter greatly improves the transfer speed of data between your computer and the hard drive. If you have a geoRAM, the geoRAM can be plugged into the RL . the geoRAM then acts as an extra piece of ram-based disk storage. The RL comes with a very well documented, thorough, and easily referenced User Manual. Contact CMD for more details. 13.3.5. What is a RAMDrive? The RAMDrive is similar in function to the RAMLink sold by CMD (see Section 13.3.4). The main differences are the smaller amount of memory (1-4 MB) and the smaller size. At one time, the RAMDrive was sold by CMD, but is no longer available through them. However, Performance Peripherals, Inc. still sells the RAMDrive unit. 13.3.6. How do I expand my C128 Video RAM? The original, "flat" C128's came with an 80 column display that had it's own display RAM that was separate from the system memory of the computer. This "VDC RAM" was 16K in size. After Commodore introduced the C128D, they changed the design and marketed some versions of the Commodore 128D with 64K of VDC RAM. Since them, some programs (e.g. I-Paint, Dialogue128) have come out that either need or support 64K of VDC RAM. Owners of flat 128's can upgrade their video RAM to 64K either by ordering an upgrade plug-in board(e.g. from Software Support International), or by replacing the RAM chips themselves. All that needs to be done is, the two 4416 RAM chips next to the VDC chip need to be replaced with 4464 RAM chips. Note, however, that since this involves soldering in tight quarters on your 128's motherboard, it is very easy to damage the motherboard or the nearby VDC chip. Whenever you wish to use the extra RAM, be sure to set bit 4 in the VDC register 28 (0 = 16kB, 1 = 64kB). 13.3.7. How do I expand my C64 internally? THE TRANSACTOR magazine published two articles written by Paul Bosacki on expanding the Commodore 64. The first article (in Transactor 9.2) described how to expand the 64 to 256kB by swapping RAM chips and contained switches to perform some special options. The second (in Transactor 9.6) describes how to expand the Commodore 64 to 1MB, using a 512kB REU and 512kB on the | motherboard. In addition, this expansion needs no switches to enable options, which is an enhancement to the first article. The Nordic/Finnish MicroBITTI magazine published a two part article by Pekka Pessi on expanding the Commodore 64. Pessi's design (in MicroBITTI Issues 1 and 2 for 1987) split the C64 memory map into 4 16kB pages, which could be each mapped to any 16kB page in 256kB of memory. It uses the same approach of swapping the 64kB DRAMs for 256kB ones, but does the addressing somewhat differently. In 1993, Marko Makela, with help from Pekka Pessi, translated Pessi's article into English and made it available via the Internet. It is now available at ftp://ftp.funet.fi/pub/cbm/documents/ or ftp://x2ftp.oulo.fi:/pub/cbm/docs/ 13.3.8. How do I expand my C128 internally? Marko Makela has written an article on how to expand the C128 and C128D's memory up to 1024kB. It is compatible with his earlier article on expanding the C64 to 256kB, so programs written for the expanded 64 should run on the expanded 128 in 64 mode. The plan and schematic is available via ftp from nic.funet.fi in directory /pub/cbm/documents/1028. The C-256 and C-512 Twin Cities 128 issues #30 and #31 have a hardware scheme for expanding your 128 to 256K or 512K. To people who understand banking on the 128, the 256K modification adds RAM blocks 2 and 3 to your system. The 512K modification adds four more RAM blocks that can be accessed as alternate RAM blocks 2 and 3, or as a completely separate set of RAM blocks 0-3. As with Commodore REUs, software must specifically support the expanded RAM. Since these modifications are relatively new, there is not much software out yet that supports the additional RAM. However, ACE 128 does support this expansion without any special drivers. The hardware modification, while simple from software's point of view, is rather difficult to perform in hardware. Richard Curcio, the designer of the memory modifications, can modify your 128 for you. See Twin Cities 128 issue #31 for more information. 13.4. How do I increase my computer's speed? There are a number of products that can increase the operating speed of the Commodore 64. These products work by turning off the on-board 6510 and turning on a compatible microprocessor, usually a 65C02 or a 65C816 in 6502 emulation mode. These products will work with any software that does not mind running up to 4 times faster and does not use any of the undocumented opcodes of the 6502 IC. Also, for a quick way to gain a small speed increase, please see Section 17.2. 13.4.1. How do I increase my Commodore 64's speed? Please note that some of these products are no longer offered for sale by the original companies, but can be purchased from individuals as used equipment. Turbo Master Accelerator for C64. The Turbo Master Accelerator is for a C64 (or C64 mode of C128) only, uses a Rockwell R65C02P4 microprocessor clocked at 4.09 MHz, has its own 64K of fast static RAM and a 32K EPROM, has hardware/software switchable speed between 4.09 and normal, and has an enhanced ROM with faster disk routines that can also be disabled. A JiffyDOS compatibility option was available. Turbo Process Accelerator for the C64. This accelerator, made by Rossm"oller, uses a 65C816P-4 microprocessor to operate the 64 at three speeds: 1MHz, 4 MHz, or anything between 50kHz and 4 MHz. The 65C816 is a 16 bit version of the 6502/6510, so it is possible to write software for the new IC that takes advantage of the 16 bit opcodes. Flash 8 This accelerator, the only one being currently produced, is also the fastest such accelerator for the Commodore 64 to date. The module, which plugs into the expansion port of the Commodore 64, increases the CPU processing speed from 1MHz to 8MHz. It uses a 65816 CPU (The 65816 is a descendant of the 65XX series) running at 8MHz to enable the increased speed. Also, it can be optional expanded to 4 or 8 MB RAM onboad. This product is the successor to the Rossmoeller TurboAccess 4MHz accelerator card. The unit has the capability to provide 10x speed disk access via a parallel cable and has a CP/M option. GEOS compatible requires the special patches that are available from the manufacturer, and games or demos which do very intensive timing or raster effects might not fucntion correctly. At present, the accelerator only works on PAL 64s of certain revisions and will not function on a C128 in 64 mode. Currenlty, the REU is not supported. From the advertisement: "FLASH 8 is a GEOS-compatible module for the expansion port with a 65816 CPU that speeds the C64 to 8Mhz by highest compatibility with existing software. Additionally to the original Commodore Kernal a JiffyDos kernal is available. You can choose between two different kernals via DIP-switch. Flash 8 comes either with 256 Kbyte or 1 Mbyte RAM onboard. A CP/M-emulator for running Z80-CP/M-Software, a macro-library and assembler for the 65816 in native-mode are included." The prices are: 349 DM (~$245.00 US) for the unit with 256kB RAM. 449 DM (~$315.00 US) for the unit with 1MB RAM. It is being manufactured and sold by Discount 2000 and Performance Peripherals, Inc. The Turbo Master Accelerator is for a C64 (or C64 mode of C128) only, uses a Rockwell R65C02P4 microprocessor clocked at 4.09 MHz, has its own 64K of fast static RAM and a 32K EPROM, has hardware/software switchable speed between 4.09 and normal, and has an enhanced ROM with faster disk routines that can also be disabled.

Although it is possoble to accelerate just about any Commodore machine, no commercial products exist to speed up other Commodore computers. 13.5. How do I increase my computer screen's resolution? Although the Commodore computers once reigned in terms or screen rsolution and number of colors available, newer machines have surpassed it in both areas. Depending on whether you want more characters on the screen or more colors at one time, these products might help. 13.5.1. How do I increase my Commodore 64's screen resolution? Since the Commodore 64's VIC-II cannot be expanded, the only way to increase the resolution of the Commodore 64 is to turn off the on-board video and replace its output with one from another IC. The simplist approach involves attaching an 80 column video chip (6545, 6845, etc.) to the C64 via the expansion port. This will provide 80 columns of monochrome text. However, this is only useful for text applications, as most of these video devices are not capable of doing high resolution graphics. Also, none of the following are currently produced, but many are sold as used equipment by users. Batteries Included BI-80 This unit combined an 80 column monochrome text video display (using the 6545 IC) and BASIC 4.0. Either options could be turned on or off via software control. DATA 20 80 column unit This unit preceded the BI80 unit, and was produced from 1982-1984. Protecto Enterprizes Protecto-80 This was basically a repackaged DATA-20 unit. Some circuitry was changed to permit price reduction, but the same functionality is there. 13.5.2. How do I increase my Commodore 128's screen resolution? The Commodore 128 comes equipped with an second video display controller in addition to the 40 column VIC chip. This chip can be used while in 64 mode through clever programming, and the controller's standard 640*200 pixel size can be expanded to 640*400. However, there is no way to completely overcome the color limitation of 16 colors + In Germany at one time, there was a small hardware device which + plugged right into the C128 and expanded the resolution to 720*700 + in C128 Mode.

The device was the + 'Graphic-Booster 128' and was marketed by: + Combo AG + Tugginerweg 3 + 4500 Solothurn + Schweiz (Switzerland) 13.6. How do I increase my computer's serial transfer speed? If you wish to operate serial devices at speeds faster than what the internal software emulated UART can handle, you will need to purchase a UART interface. There are a couple of different kinds, and each has its advantages. To use these hardware UARTs, the application must be written to take advantage of the device. SwiftLink the SwiftLink cartridge is manufactured by CMD and allows speeds up to 38.4 Kbps. This device contains a 6551 UART and plugs into your cartridge port and supplies you with a standard 9-pin serial port. You then connect the desired modem. Dialogue128, Novaterm64, and Kermit(v2.2s) support the SwiftLink. Creative Micro Designs, Incorporated. (CMD) 15 Benton Drive P.O.

How do I increase my computer's sound quality? SID Symphony The C64 and C128 come equipped with 1 Sound Interface Device (SID) IC. This provides 3 channels of output. For more channels, one can purchase the SID Symphony cartridge from CMD to provide 3 extra channels. Most newer sound playing and editing software is able to use the extra channels. There are also a number of units one can purchase or build that will provide MIDI capabilities for Commodore 64 and 128 users. 13.8. What other ways can I expand my Commodore computer? There are many hardware items that you can use. Below is a list of a few of them. Note that some of these items may no longer be in production, and thus are only available as used equipment. 80-Line Simplified Digital I/O Board This unit has 40 TTL input lines and 40 separate buffered digital output lines plus an expansion socket that could support a standard ROM or clock/ calendar cartridge. It works on the C64 and all modes of the C128 (including CP/M mode). Its model number is the SS100 Plus. "Original Ultimate Interface" This is a universally applicable dual 6522 Versatile Interface Adapter board with four 8-bit fully bidirectional I/O ports, eight handshake lines, and four 16-bit timer/counters. It has IRQ interrupt capability and is expandable to four boards. It works on the C64 and all modes of the C128 (including CP/M mode). Its model number is the 641F22. A/D Conversion Module This unit is 16 channel, 8-bit, 100 microsecond conversion time. Piggy-backs on the 641F22 and thus requires it to operate. Works on the C64 and all modes of the C128 (including CP/M mode). Its model number is 641F/ADC0816. The Spartan Apple ][+ emulator for the C64, by Mimic Systems, Inc. In addition to allowing the use of Apple ][+ hardware/software, this device boasted four software selectable C64 cartridge slots, a non- dedicated 8-bit parallel port, and standard audio cassette deck capabilities for the C64. ROM upgrades are available for the C-128 and the 1571. C64 Games Port Expander (Model #8401) 40/80 column converter. Switchable, it has 4 independent cartridge sockets plus a 5th switch position accessing an 80 col. character set ROM - (limited usability because it *apparently* accesses a C64 Ram location which interferes with a lot of stuff, I forget where or how) - and a 6th switch position independent of the cartridge port for general use stuff. It was built into a neat steel housing designed to sit flat on the desktop and slide into the cartridge port at exactly the right height. --------------------------------------------------------------------------- Table of Contents (for this file) --------------------------------- 14.

Credits --------------------------------------------------------------------------- 14. Programming 14.1. What Programming Languages are available? The following programming languages are known to exist for the CBM computers: Ada APL Assembly Language BASIC (interpreted and compiled) BASIC extenders C COBOL COMAL FORTH FORTRAN LISP LOGO MUMPS Pascal PILOT You name it, and it is probably available for the Commodore computer system. The list of supported languages availeble for the Commodore 8 bit computer systems is much too large to fir in the FAQ, but they are available at http://www.wimsey.com/~danf/cbm/languages.html. 14.2. What is a Cross Assembler? How do I use one? A cross assembler is a program that runs on one computer and generates code for another computer. Usually, a non 8-bit CBM machine generates the code using this program, but it can be another 64 hooked in some way to a "target" 64. Whatever the case, here are some packages that can be used: as6502 linking 6502 cross assembler masm6502 6502 macro cross-assembler ps65a12 Unix format 6502 cross assembler svasm02 6502 cross assembler xasm220 many-targeted cross assemblers smal6502 linking macro assembler written in portable PASCAL A more detailed list can be found at: http://www.wimsey.com/~danf/cbm/cross-development.html For all cross assemblers, the user will most likely benefit from a way to transfer the program from the source platform to the target platform. See Section 7 for information on products that will help transfer the files. 14.3 What is an "undocumented opcode"? In the 65XX CPU line, each machine language instruction is a single byte, which allows for 256 instruction types, or opcodes. However, there are fewer than 256 defined. When designing the 65XX line, the designers, needing to keep complexity down, decided to treat the extra opcode positions as "don't care" opcodes, where no effort would be made to make those opcodes do anything special. Since the opcodes are arranged in a 16X16 matrix, with a row or column cotaining opcodes that perform similar operations, an undefined opcode in the matrix can have the behavior of other opcodes in its row or column or both. These opcodes are called "illegal" or "undocumented" opcodes, and are occasionally used by demo coders to accomplish special timing effects, or by software programmers for copy protection code. To learn more about these opcodes and what each does, the get the 64doc file at ftp://ftp.funet.fi/pub/cbm/documents/64doc or visit a cbm emulator forum. 15. User Groups User's Groups fulfill a major function for Commodore owners. They provide a place to meet other users, discuss problems and solutions for computing, teach and learn information about their machines. Software can be shared and friendships are made. The Commodore community is made up largely by real or virtual user's groups. A complete list of Commodore user groups can be found at | http://www.msen.com/~brain/pub/cbm-ug-list.1.0.txt This file is also available from Jim Brain's MAILSERV server as file | cbm-ug-list.1.0.txt. (See Section 6.5.2 for directions on using the | MAILSERV server.) Commodore owners are encouraged to join a CBM user group to help keep these vital organizations around. In addition, most user groups publish newsletters 16. Sales and Service Sooner or later, every Commodore owner will need to get his or her computer serviced, add another peripheral, or simply purchase some enhancement hardware or software. Contrary to popular belief, there is a large base of hardware and software suppliers and service centers. 16.1. Where do I purchase Commodore Equipment and Software? ESCOM (holder of the Commodore patents and copyrights), does not currently manufacture Commodore 8-bit computer systems. Many online services, including GEnie, the Internet, and user group newsletters contain classified ads from individuals wanting to sell used CBM equipment, however. In Germany, there are a number of shops which still sell factory new Commodore 64 and Commodore 128 computers. ESCOM also does not manufacture software for the Commodore 8-bit line. However, many companies still sell software for the Commodore line. A complete list of Commodore hardware, peripheral, and software suppliers | is available at http://www.msen.com/~brain/pub/cbm-supply-list.1.0.txt, | as on Jim Brain's MAILSERV server as file cbm-supply-list.1.0.txt | (See Section 6.5.2 for directions on using MAILSERV). 16.2. Where do I get equipment serviced? There are a number of repair facilities around that will bring your trusty Commodore computer up to speed again. Please look in the list below for one that might be able to help you. If that doesn't turn up anything, check with your local User's Group. A complete list of Commodore software and hardware repair facilities can | be found at http://www.msen.com/~brain/pub/cbm-repair-list.1.0.txt or | at Jim Brain's MAILSERV server as file cbm-repair-list.1.0.txt. | (See Section 6.5.2 for directions on using MAILSERV) 16.3. How do I know who to buy from or request service from? The information provided in this file does not imply that a company is reputable or even still in business. It is best to use the above information as a starting point, and contact others who can discuss the various manufacturers and repair facilities listed above. 17. Miscellaneous Well, this is where the chaff falls. The following questions are either too new to categorize or do not fit into a category. 17.1. How fast does a Commodore 64 run? If you are using a stock Commodore 64, the CPU clock frequency is a function of the video timing frequency, which is slightly different for differing countries. If you have a stock PAL-B C64 (Common in Europe), the computer is running at 985248.444Hz. If you are using an NTSC-M C64 (Common in the USA), the computer is running slightly faster, at 1022727.143Hz. 17.2. How can a turn my NTSC-M 64 into a PAL-B 64 or vice versa? Changing a C64 from stock PAL-B to stock NTSC-M or vice versa requires swapping in the approproate VIC-II chip and the appropriate crystal, as well as changing a jumper on the motherboard (The jumper has printing near it that indicates whether to cut or connect the jumper). Also, if you have a version 1 KERNAL ROM and want to use the built-in RS-232 routines, you need to either swap KERNAL ROMs with the other computer (not recommended), or obtain a revision 3 KERNAL (recommended). Now, if maintaining stock operation is not a complete must, or if you just want to tinker, the crystal and jumper modifications can be made optional. The VIC-II chip has a relaxed tolerance for timing, so it is possible to run an NTSC-M VIC-II with a PAL-B crystal and jumper settings. The converse is possible as well. Since the crystal frequency is used to generate the frequencies for the TV and monitor output, your TV or monitor may not like the resuling hybrid signal very well, but it won't break anything. In addtion, the jumper indicated above determines the divisor used to scale down the crystal frequency for the CPU. For PAL-B units, the divisor is 18, and for NTSC-M units the divisor is 14. The Commodore 64 will operate regardless of the crystal frequency and state of this jumper. Therefore, to speed up a 64, one can install a PAL-B crystal (17734472Hz) and change the jumper to use the NTSC divisor (14) to increase the operating speed of the machine to 1266748Hz. However, note that any operations (disk, rs-232, special VIC tricks) that require synchronized timing may fail in this "non-stock" scenario. 17.3. What does this IC number mean? Here are a few Commodore IC numbers and their functions. Note that this | is an incomplete list. A more comprehensive list is called csg.chips.info and is at ftp.funet.fi.

The newer boards put all the PLA and LSI logic into one ASIC chip. On the older boards, the KERNAL and BASIC ROMs were separate, while they are combined in the newer design. There are two different models of the narrow board. One has Color RAM, while the other does not. The ASIC chip includes the PLA and 7 TTL chips, and the Color RAM on some machines machines. The new models use 9 volt versions 8580 SID, while older models use the 6581 12 volt SID. The VIC chip (6567 NTSC-M, 6569 PAL-B) has been replaced with the 8562 (NTSC-M) and 8565 (PAL-B) on newer models. Both BASIC 2.0 and the KERNAL ROM have been combined into one ROM for the C64C/G/GS. This ROM is the same as is used on the C128 in C64 mode. The ROM is indentical except for nationality differences. + 17.4.
