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 ============================= Archive contents ============================= Original Packed Ratio Date Time Name -------- ------- ----- --------- -------- ------------- 7499 2666 64.4% 31-Dec-97 18:00:00 AmigaComm.source 32972 14159 57.0% 31-Dec-97 18:00:00 Apple 422 213 49.5% 31-Dec-97 18:00:00 Apple.info 20272 10605 47.6% 31-Dec-97 18:00:00 AppleComm 422 210 50.2% 31-Dec-97 18:00:00 AppleComm.info 219 144 34.2% 31-Dec-97 18:00:00 Bugs 469 227 51.5% 31-Dec-97 18:00:00 Bugs.info 5568 2288 58.9% 31-Dec-97 18:00:00 Readme 469 227 51.5% 31-Dec-97 18:00:00 Readme.info 287 168 41.4% 31-Dec-97 18:00:00 TODO 469 230 50.9% 31-Dec-97 18:00:00 TODO.info 0 0 0.0% 05-Jun-94 09:06:58 txt/ 283 155 45.2% 31-Dec-97 18:00:00 txt/ACASLReq.def 469 228 51.3% 31-Dec-97 18:00:00 txt/ACASLReq.def.info 3183 1115 64.9% 31-Dec-97 18:00:00 txt/ACASLReq.mod 469 230 50.9% 31-Dec-97 18:00:00 txt/ACASLReq.mod.info 95 83 12.6% 31-Dec-97 18:00:00 txt/ACGadgets.def 469 227 51.5% 31-Dec-97 18:00:00 txt/ACGadgets.def.info 2495 701 71.9% 31-Dec-97 18:00:00 txt/ACGadgets.mod 469 226 51.8% 31-Dec-97 18:00:00 txt/ACGadgets.mod.info 46458 8312 82.1% 31-Dec-97 18:00:00 txt/Apple.mod 469 231 50.7% 31-Dec-97 18:00:00 txt/Apple.mod.info 22531 6485 71.2% 31-Dec-97 18:00:00 txt/AppleComm.mod 469 228 51.3% 31-Dec-97 18:00:00 txt/AppleComm.mod.info 506 275 45.6% 31-Dec-97 18:00:00 txt/AppleScreen.def 469 232 50.5% 31-Dec-97 18:00:00 txt/AppleScreen.def.info 13372 3701 72.3% 31-Dec-97 18:00:00 txt/AppleScreen.mod 469 230 50.9% 31-Dec-97 18:00:00 txt/AppleScreen.mod.info 463 311 32.8% 31-Dec-97 18:00:00 txt/Base37.def 469 228 51.3% 31-Dec-97 18:00:00 txt/Base37.def.info 393 224 43.0% 31-Dec-97 18:00:00 txt/Base37.mod 469 228 51.3% 31-Dec-97 18:00:00 txt/Base37.mod.info 628 277 55.8% 31-Dec-97 18:00:00 txt.info -------- ------- ----- --------- -------- 164165 55064 66.4% 12-Jan-93 14:44:34 33 files
