These files comprise a PD 8080 (CP/M-80 2.2) emulator that runs under CP/M-68K. The emulator is the one published in DDJ. I made some modifications to properly handle the base page setup for the target processor (this only affects programs which use the second FCB in the base page). Here is a directory listing on the files on SIMTEL20: Filename Type Bytes CRC Directory PD:<CPM.CPM68K> COM2.68K.1 BINARY 23808 5707H COM2.LBR.1 BINARY 50688 7230H The .68K file is a ready-to-run relocatable executable. The .LBR file contains the source code (four squeezed .s files and two undsqueezed .sub files for re-building the .68K file). Note: this is a straight 8080 emulator. There are hooks for some of the Z80 instructions, so an enterprising 68K assembly/Z80 hacker can implement a Z80 emulator. These files also exist on GEnie (in the CP/M RTL) and on BIX (listings, cpm area). I don't know if Keith Peterson downloaded to his RCP/M system or not.
