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.
