Moved the Galaga 88, never really messed with it since it worked ok when I got it from Namco.
Gave it a quick look over, fire it up and nothing...
Powered down and gave it another look and found a ground wire tied in a knot behind the weird jamma connector board...and it was shorted to the +5 line. Also noticed the +5 and ground wires at the power supply were just twisted and jammed under the posts...fixed that and reconnected the knotted ground wire...
And now the game won't boot.
I get a rom test screen that goes white to red and then blank screen.
I'm guessing that ground line cooked something, but not sure what.
Any idea where to start?
