I'm in the process of clean-up and consolidation, as I mentioned earlier. I re-found an old C-64 board of mine and I'm trying to place it in its historical context. I know it's old because it has a 5-pin DIN for a video connector. Inside, the board says Rev B in copper. Were any Rev A boards released? The PLA has a typed sticker that says... C64 REV2 7E17 U5 is p/n 901225-01, U4 is p/n 901227-01, and U3 is p/n 901226-01, all soldered in place. U19, the VIC chip, has a date code of 2482 and no revision on the 6567 p/n. The only remaining anomaly is a wire-wrap wire trailing from pin 28 of the 6510 socket. I suspect I put that there for my Batteries Plus IEEE-488 cart. I suspect that this is from my oldest C-64. I used to program it for a living between 1982-1984. The very first one we got at work was a freebie from C= in exchange for writing software for it. It was serial number 2007. It also didn't work reliably. I'm told that the first run of 6567 chips had a flaw that caused a light-pen IRQ when the chip got warm. It was June of 1982. It was warm out. I would get a blue screen after 45 minutes to an hour of operation. We traded our original one to the local dealer for a replacement. If I am correct, this is that replacement. The software from that summer never hit the market. The PC version was released and sold as "WordVision" and required 96K of RAM and DOS 1.0 on the PC. I did complete a demo for Comdex '82 that I still have. I should upload the files to funet as an example of the state of things circa September 1982. It's a nice piece of vaporware. The only thing that was completed for the C-64 was that demo. :-( Thanks in advance for any information on ancient C-64's that anyone can dredge up. -ethan _________________________________________________________ Do You Yahoo!?
