Dig Dug

I received this off a fellow collector for a Q*bert I traded him. The game works, the cabinet is solid but the artwork is a little beat.

The screen has some serious burn but is not too noticable during gameplay. The marquee and bezel are in really good condition.

Control panel is a little beat too... :(

After playing a few times I noticed that the Hi-Scores were not saving as suggested in the manual. After checking the schematics and doing some research I found that the ER2055 chip at 10G is what holds the scores and requires +29VDC to function properly. I took out my DMM and tested for +29V at the test point and was only getting +2.1V. A quick post to KLOV (http://forums.klov.com) and a fellow collector informed me that the -29VDC is supplied by the +36VAC coming from the power brick. I pulled out the schematics and checked for +36VAC at the edge connector... no good, then the power brick... good. I followed that to the fuse holder and sure enough the fuse was blown. I replaced the 4A, 250V SB and powered the game back up. The fuse held and I was getting +29V at the test point. I played a couple of games, scored 126k and turned the game off. I came back a little while later and the score stayed.

I was informed that there is another local collector that has a cabinet in better shape for sale. I am hoping to get this and transplant the guts. We shall see...
