I had only limited experience with the 128 - A friend had one. 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.)
