When I got this Q*Bert, it was missing a power supply PCB. I ordered one online. While waiting for it, I figured I should clean up the power block in the bottom of the cabinet, and test the components on it:

It was pretty corroded. My goal here was not to make it spotless, but just make it presentable and ensure everything was working. I cleaned it up with some wire brushes and steel wool, and checked all the fuses to make sure they were the right values and that they were working. I also tested the 2 bridge rectifiers. Everything tested fine. Here it is cleaned up:

I hooked this back up in the bottom of the cabinet and waited. I received the power supply PCB earlier today, and hooked it up. It shows some signs of life now:

As you can see, some of the wrong sprites are being pulled up. Where the spinning round discs should be, there are those green guys. Where the “Q*Bert” logo should be is a bunch of garbage. When Q*Bert moves up the board, his sprite changes to coily. Here’s a video of it in action:

It’s been a long day, so I think I’ll call it quits for now. When I get back at it, I’m going to go over the other boards to make sure everything is OK. I also need to work on the knocker, as it’s not firing.
