I don't think those parts are socketed on any stock C-64 (I have a test machine from a former CBM dealer that had every part removed and sockets installed), but it would be a good reason to install sockets for a test. I would do it myself but I don't own a CP/M cart. Never had a reason to get one, so I didn't (I have a Kaypro 2 for "real" CP/M work - only for demos at Vintage Computer shows in recent years). My personal interest in CP/M applications is pretty much limited to running Infocom games (Zork I et al.), and Scott Adams adventures. Back around 1985, I had occasion to use CP/M machines at work and in the field while studying archaeology (before PCs completely took over), but even that was mostly entering text and simple database stuff that fit on a floppy. It would be entertaining to see CP/M running on a C-64, but I would consider it much like the dancing bear at the circus - it's not how well the bear dances, it's that the bear can dance at all. Back in the day, C-64s were derided for not running whatever the speaker's favorite app was on their favorite platform (Apple II, PC, etc)... it would be interesting to see a C-64 do something it didn't normally do (and I did happen to have one of those Spartan "Mimic" Apple II emulators - essentially a headless Apple II that stuck out the back of the C-64). -ethan Message was sent through the cbm-hackers mailing listReceived on 2012-12-20 20:00:06
