Two years ago I bought this MK2 board but did not get it working. I tried to have my PC find the board with no luck. Admitted I am not very good at the software part, so I put aside the board for a period. Then I met a person who had one too and he told me how to upgrade the software. This done I put some chips in but it was not working. I thought the chips were not working and tried to find some on eBay. Finally I got some chips but still no luck. Then yeasterday I met a third Commodore 64 fan who had several working boards. We used three different working VIC-II chips but all gave the same error: Error: VIC-II is not recognized, check U19.
I have tried cleaning the socket. I have tried measuring the connection from the chip to the bottom of the board (no problem here) and I have tried with other SID chips and CPU chips. And finally I have tried to use the former software and the the newest version. All with no luck.
