Wizard of Wor Resetting

Wanted to try the game again tonight to see if I had any problems with it resetting. Well, after turning it on, that is all it did, every second it reset and the game just kept flashing, so there is something wrong with it. Some information is turning up on the Google Groups, it may not be too complicated to get working again.

I also spoke with Rick tonight, and he was fairly familiar with the hardware in these Wizard of Wor machines. Made by Midway / Bally, the hardware is very similar (which I already read) to Gorf, and apparently Professor Pac-man. He said it sounded like a Z-80 processor possibly going bad since there is already a switching power supply installed. He said it can never hurt to clean the edge connectors, all sorts of weird problems can happen there. As I had read before, and he suggested again, to use Scotch Brite pads. I have to figure out which ones. I have heard about using the magic eraser ones, but apparently that isn’t what you use for edge connectors.
