Message-ID: <8804270752.AA16125@ucbvax.Berkeley.EDU> Date: 26 Apr 88 13:01:00 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 13 Bill: There is a PD CP/M 2.2 emulator that runs under CP/M-68K. It is on Simtel20.ARPA as COM.LBR PD1:. The .LBR file is a LU310 compatable library file and contains squeezed (USQ210) sources files, in 68000 assembler. This emulator runs under CP/M-68K and has a "dummy" BIOS/BDOS, which just transfer control to the CP/M-68K BIOS/BDOS. Does not have a CCP - run one CP/M 2.2 program and returns to CP/M-68K's CCP (i.e. piggybacks on CP/M-68K's CCP). Under UNIX, I guess you'll have to write a "real" BIOS/BDOS which fake it and call UNIX system functions. This emulator is mainly an 8080 emulator - does not fully emulate the Z80, although hooks are there. Speed: about 1Mhz 8080 on a 10Mhz 68000. Simtel20.ARPA supports anonymous FTP on ARPANet. I don't know if this helps any. Robert
