Slippyblade:
Thanks for the advice, Opt. The caps on all the boards look good, very smooth, no bulges. Not to mention that sometimes the game DOES work. I'm seriously thinking it's the connector cables or the pins. Tonight I'm gonna pull the boards, reflow the solder on the pins, and check the cables. While those IDE connectors look like a great idea, I am doing this on-the-cheap as much as possible.

Overall, the boards look amazing. The battery holder will probably need to be replaced though. The AAs that were in it leaked slightly so the holder is corroded. Gonna try cleaning it really well first. Not sure that would cause the symptoms I'm seeing though.

cw:
also check cold solder joints on power pcbs and main pcb..

Slippyblade:
Looks like I got the main problem on Joust #1 worked out. The main power connector to the CPU board had a bad connection. The +12v line wasn't making a good connection. I cut it out and reseated the wire in the blades of the connector and it is working reliably now. Now I need to figure out why I've got no sound and then rebuild the joysticks and deal with the battery holder. Bob Roberts has a great little hack to replace the AA battery holder with a CR2032 lithium that I think I'll do.

Slippyblade:
Ok, sound issue us a bad connector as well. Grabbed a pic pen and jammed all the wires deeper into the blades on the connector and wiggled the ---steaming pile of meadow muffin--- out of the plugs and sound is working now. I'll reflow all the solder connections on these connectors this weekend just to make sure. This is so awesome!

That joust looks like it's in great shape. Aside from the issues that you are fixing is there anything wrong that I am missing on the cabinet itself?
