OP

Quoted from ranger-danger:

Hi,
Thanks for the replies folks, that really helps. Machine (and myself) are in Northern NM. Doubt anyone knows me, I'm new to the forum.
Machine plays though it's a project and has some gremlins to get out. There's a sticky switch so sometimes scores will shoot up to infinity. Probably there are some bad power transistors on the lamp driver board. No battery damage to MPU though. I'll take some more pictures and move this over to a sale thread.
