     What IS this thing I've just downloaded!
     ----------------------------------------

     Well, simply put - This is an emulator, that trys its best	to 
     emulate a Commodore Plus/4 On an IBM compatable PC. Theres loads
     of info and games available at ftp://ftp.funet.fi/pub/CBM/plus4
     if you want some more information, then drop by my homepage at
     http://www.scotch.demon.co.uk




     How do I use it!
     ----------------
     Well, the first thing you'll need to do, is get ROMS required to
     run it. These are "c16basic.rom" "c16kern.rom" and "c16char.rom"
     There is also the built in 3-plus-1 ROMS. 
    
     These are all available from ftp://ftp.funet.fi/pub/CBM/plus4 or 
     "www.scotch.demon.co.uk"


     The ROMS must be called "3plus1lo.rom" and "3plus1hi.rom" for Minus4
     to find them.

	

     Loading a Game
     --------------
     To load a game (a .PRG or .D64 file) specify the "PATH" on the 
     command line. for example:

			    "minus4 games"
     
     Then once in the Plus/4 emulator, press F10 to get to the loading
     menu. Once a game is Loaded, it will have to be "RUN", so type "RUN"
     and thats all!
     

     PLEASE NOTE: DONT TRY AND LOAD ANYTHING USING FROM DISK OR TAPE
                  ONLY F10 WORKS JUST NOW!




	
     How do I quit!
     --------------
     To quit, press "ALT+BREAK" this should return you to dos.
     If your in windows...it probably wont! 
     Windows grabs the ALT key - try and exit through the monitor.



     The Monitor
     -----------
     Escape- return to full speed emulation
     F12   - reset Plus/4 (also exits monitor)
     F5    - View frame
             Space = render next scan line. Actually processes a
                     scan line of 6502.
             Escape= return to debugger.
     F6    - Save current view. type in a name.bmp then press
             enter. Remember DOS filenames!
             Also remember that it saves the CURRENT view. So, if
             you were view the display, and pressed space for a
             while, it will save 1/2 this and 1/2 the last frame!
     F9    - Trace FAST
     Enter - Trace SLOW
     M     - Dump memory
     S     - Run to
     R     - set PC to address
     Q     - Quit program (back to DOS)



     Joystick!
     ---------

     F5 will enable joystick 1
     F6 will enable joystick 2
     Both use the cursor keys and SPACE. A redefine option will be
     added later. I will also add "real" joystick support soon.


     Whats NEXT!
     -----------

     Disk emulation

     Sound needs done one day too!

     And so does the Timer and its IRQ's... (1 down 2 to go!)

     One day I'll write the Cursor routine correctly! <g>

     I'd also love to map the PC's serial and parallel ports on to
     the Plus/4's User port!! That'd be really neat!

     I've gotten a hold of the OS96 from solder, so I may add a
     boot menu as well. If I get it working!
     (This DOES run just now! If you replace the C16Basic and
      C16Kern ROMS!!)

     PAL/NTSC switch! ($ff07 - bit 6, $40)

     How about a packer that allows you to run "snapshots"  on the
     actual Plus/4???

     256K memory emulation. 

     Any suggestions are welcome!! Honest!! Really!! Send some!!
