I just acquired a Ms Pacman cocktail for cheap (FREE!). It's by Midway and has 1981 overlays. I plugged it in, and the lights above the joysticks and quarter slots worked but nothing else. I didn't get a key with it, so i had to dissassemble it from the top down to get inside to start to figure out what is wrong with it. It appears to be in pretty good shape but there is a connector hanging with nothing to plug into. I noticed some racks that look like they could be the home of some PC cards, but they are both empty (looks like one large card and one smaller used to reside here).

What would you do with it?

Where can i get a maintenance manual? I'm electromechanically inclined, so i'm pretty sure i could figure it out with a little help. I want to keep it, restore it, or possibly upgrade it if it makes sense. Is it the mother card and a daughter card that are missing? What other forums/web sites/books are there for resources?

Thanks!!
