Applicard CP/M on Apple ///!



Not sure how many folks in this community own Apple ///s, but I've made a very interesting discovery.

A few weeks ago I was fortunate enough to score an Apple /// Appli-card with documentation and system diskettes. I had seen mention of this board in advertising from 1983, but didn't realize it had been shipped as a product! The diskettes had grown mold, but with a little TLC I was able to clean and read them without errors.

The board itself has hardware problems that I'm still chasing down, but after looking it over I realized that it used the same boot EPROM as the A2 Appli-card and appeared to have essentially the same chip complement (although in a different form-factor). Taking a leap of faith, I plugged my Freed Z80 card into the A3 (a real A2 Applicard is too long to fit) and booted the system disk.

Lo and Behold! It came right up in CP/M :-). This is very exciting news in a geeky sort of way. I'm going to release images of the system diskettes and a scan of the manual ASAP in case other folks with Apple /// or ///+ systems want to try this. There is driver support for running CP/M from the ProFile and I'll be trying that next - but have no reason to think it won't work.
