So while I am awaiting my capkit for my other project, I pulled the second arcade of my recent haul out of the storage building and started working on it. It is one of two Ms Pacman machines. At first when I plugged it in, it came on but with garbage on the screen. I decided to clean the thirty-four years of dirt and grime out of it so I could get a closer look at what is going on. After vacuuming that out, I pulled back the safety switch and the screen went to a test pattern and then the game fired right up! I did notice that the joystick wants to stick to the left, but I bet with some cleaning that will go away.
The color on the screen wasn't perfect but I couldn't find where to adjust that. on the monitor. I will have to take a closer look and see what is going on with it. Other than that, I just need to fix the lights and the cpo. I don't know if it would be worth it to try to fix the artwork. If I try to repaint it, I will have to fix all of the wood on the whole cabinet and then get the stencils.
Can anyone tell me what is going on with the PCBs? Does it have a speed chip on it? I ask because Ms Pacman is flying through the maze.
Here are the pics:

You can see the damage the coin door has from being on location. Someone had tried to pry it open.


These internal shots are from before I cleaned it.
