I've got a Commodore PC III that worked until the NiCd battery leaked. :-( It wasn't in storage, I used it right up until it failed to drive an old EPROM/GAL programmer (B&C Microsystems UP600A). That programmer was one of the early ones with 40 pins of D/A waveform control, so it could program "anything". Unfortunately, B&C stopped developing for it, so there are no new code files for newer devices than about the early 1990s. I did find a stash of files with the app that made it seem like you could also test TTL chips with it, but I couldn't get those to work. I used the PC III because the programmer has a proprietary parallel card to drive it and the app appears to have timing loops that make it fail in anything as new as a 25MHz 386, so I tossed the parallel card in the PC III, dropped in an 8-bit NIC, and used DOS Kermit to move files via TCP/IP from my Amiga down to the basement so I could program GALs for the GG2 Bus+. When the PC III died, I moved the cards to a Compaq 286/SLT dock and use that to run the programmer now (after some RTC battery hacking). I did like the AUTOCONFIG-like stuff that Commodore tossed into the PC III. Not quite jumperless, but it handled a few of the more common configurations IIRC. One of these days, I intend to go back and repair about 4 cm^2 of damaged traces and see if I can get the board working once more. As of last month, I now have an inspection microscope, so that may help identify corrosion that's not immediately visible. -ethan Message was sent through the cbm-hackers mailing listReceived on 2011-10-21 15:00:03
