Hi, All, I set up a retro-gaming event at our hackerspace over the US holiday and I brought a couple of VIC-20s (since I hadn't fired them up in a while and didn't know if one or both had problems). Turns out, it's good that I did. One was fine, the other was not. The one with the problems - the biggest issue I had, as an example, was while playing Gorf from cartridge, the sound cut in and out while the game played. I can easily swap out the 6560 VIC chip in case that's where the problem is, but are there any other diagnostic things I can do? Another symptom is the colors weren't quite as "bold" as they were on the working VIC-20. There was still color, but on a no-cartridge bootup to BASIC, the border wasn't quite the same color, and when playing Gorf, the colors weren't as saturated. Could be related, could be two different problems. It's been a while since I've debugged a VIC-20, so pointers to checklists and such are most welcome. Thanks! -ethan Message was sent through the cbm-hackers mailing listReceived on 2017-07-05 19:00:02
