I was on my third CP/M machine myself - this one had a 20M hard drive, as well as both standard and double-density 5-1/4" drives. We found that IBM-PC format made the best exchange format between us. I still have a fair collection of software for CP/M - including Word Star word processor, Personal Perl database, Both standard and macro assemblers, a C compiler, modem programs, etc. I wish I could legally add them to one of the CP/M software sites. I used to write a lot of serial port and modem overlay files for the modem program. (MEX?) Some were simple changes to add the carrier detect bit, while others were full overlays for new hardware based on the default template. I don't know if they are still floating around. There should also be a Battle Ship type game and a Number Squares game written in C out there someplace. (Text based.)
