I just picked up a Pac Man upright this weekend. It's in great shape but isn't working. Looks like the manual references both types of boards for schematics, wiring, etc. Is there a relatively easy way to tell if your pcb is "A" or "B" quality?

as far as I can tell from research it has to do with the custom IC's. Does your board have daughter boards. if so its a B.

Basically, NAMCO made a custom chip for the Pac-Man board to prevent piracy, etc. And, well, I think Bally ran out of them and reverse engineered it and replaced it with all those parts on the daughterboard. I am not sure if that makes it an A or B though. The board itself is technically the same, it's just that one chip. |

Thanks! I'm probably going to have it tested at least. It has 2 daughter boards.

John, do you have a reputable person who tests and repairs pcb's at a reasonable price?

I do boards cheap. At the moment I only ask for shipping to be paid. As far as I know Adam is no longer taking repairs.

One because it's john's forum and I give deals to people here and two because I'm still a nobody in the repair world. As far as pac man is concerned I can just trade you my spare working board and keep your broken one.

That's cool. Well, I don't know if mine is broken yet. I need to replace fuses, check the power supply, then make sure there are no unwired parts. This thing sat in a garage for 15 years.

It'll be a couple of weeks before I can get to it, but I'll contact you as soon as I've eliminated the other possibilities.
