Excellent! I just bought a copy and will see if I can figure out turbo pascal so I can compile it. I have not used CP/M in a long time.
Sad news. I either don't have a C64 old enough to use the CP/M cartridge or the cartridge itself is bad. I tried it on 5 different breadbins, a C64C and even a C64U. On one of the breadbins I had some action from the cartridge after loading the disk but never got to the CP/M screen. I think I sold my oldest C64 a couple years ago. Maybe I will see if it will run on one of my Commodore 128 machines instead. Alternately I'll figure out how to load it on my Osborne 1. That would be cool.
