Short: Apple 2 emulator written in Modula-2 Apple 2 Emulator ~~~~~~~~~~~~~~~~ (written and put into the public domain by Claudio Nieder) Version 0.1, 03-Jan-1993 ~~~~~~~~~~~~~~~~~~~~~~~~ This is the first version of an Apple 2 emulator I'm writing. Although this is a alpha test version, it is quite stable. It doesn't produce any enforcer or mungwall hits. It doesn't loose memory. The emulator is written in Modula-2 and was compiled with M2Amiga V4.1. What you need ~~~~~~~~~~~~~ You should have a fast Amiga. I am using it on a 25MHz Amiga 3000. You should have at least 0.5 MByte contiguous memory free, when loading the emulator. You should have at least Workbench 2.04. You should have an Apple 2 from which you can transfer the ROMs and the contents of your Apple 2 floppies to the Amiga. You need a cable to connect the annunciator ouput port 0 (AN0 on the game paddle connector) to the receive data input of the Amiga serial port. You need a way, to transfer the audio output from the Amiga to the Apple 2. This can be either done, by first recording the output of the Amiga on a tape, and then playback it to the Apple, or by a direct cable. I have tried the first method only, using two different tape recorders, so I didn't need to get a special cable. What it does ~~~~~~~~~~~~ Currently it emulates an 48K Apple 2 with two disk drives. Only the text page can be displayed until now. It runs BASIC programs at about 1/10 the speed of an original Apple 2. Disk access can be as slow as 1/60 of an original Apple 2. So you have to be patient when booting. This may take 5-6 minutes. The disk drives are also emulated, i.e. you don't connect directly your Apple 2 disk drives to the Amiga. You can use your Apple 2 to tranfer the contents of a floppy to the Amiga. On the Amiga you can use the floppy for reading and writeing, but at the moment it is not possible to save back a floppy. Bugs & Questions ~~~~~~~~~~~~~~~~ If you have any bugs to report or questions to ask: Before March 1, 1993, you can send me mail (claudio@chuug.ch). After March 1, 1993, you should ftp the newest AppleOnAmiga.readme from ftp.eunet.ch [146.228.10.15] to see, if the program was updated. claudio
