I just picked up a set of 3 boards and put them in last night. At that point they worked good for an hour or so.
I should also mention that the old battery was cut off the power supply board, so I installed a bob roberts high score save battery holder and lithium battery.
Ok back to the original point.
The game developed some sprites or graphics issues.
I haven't had time to test voltages yet, or do anything.
During play, the sprites disappeared, then came back 10 minutes later.
where should I start?
