Howdy.
Been working on giving my Joust an overhaul. It's been sporadic and acting haunted for a while. (games starting by themselves, controls not working at all, ram errors, sprite glitches, red popping in and out) Some days it's a champ and sometimes it's all over the place. Needless to say, I've rebuilt the PSU, recapped the boards, replaced all the connectors, cleaned / reflowed the pins and replaced the ribbon cables. And I'm still having a few issues here or there. I'm in the process of doing a RAM upgrade but there's 1 input issue that's still happening. The player 2 flap is stuck closed. I even booted with the CP unplugged and it's still closed. I've traced it out and the switches are fine and the wiring looks good. So I was wondering if anyone has an idea where to source the input PIA chips or other things I can diagnose?
Thanks,
