channelmaniac #1 Posted June 8, 2017 Picked up one of these at a computer surplus store while out on a business trip... Wasn't even sure what it was when I bought it. I only bought it for the chip clip and ribbon cable that was on it, but when I opened it up... WOW! "Diagnostic clip I, C 1980, Commodore, Made in USA" I couldn't find much for it online... so I sent pics and code dumps to Andre Fachat since his page said he was looking for info. Well, tonight I had some spare minutes so I traced out the board. Enjoy! Raymond Quote Share this post Link to post Share on other sites
7800fan #2 Posted June 8, 2017 Looks like it loads custom program from the 2x EPROMs. Make sure that gets dumped, 40 year old EPROM aren't good at keeping memory. Quote Share this post Link to post Share on other sites
