Well it looks like my luck turned a little sour. The graphical glitches came back. They come and go now. I am going to start by removing the PCB and attaching 5V and Ground to every test lead I can find. A couple of the edge connector pins are burned which I found out is relatively common with Pole Position. The guy before me only attached an additional 5V to one spot on each PCB. I am going to power the PCB with a modern switching power supply to see if that and the additional power distribution wires calm things down. If that works I can clean up and refurbish the original power supply at my leisure. |

Not quite sure what your working on, But that sounds more like a bad ground , faulty cap, or transistor given the burnt pins... If it did work something has changed in terms of draw. |

| Mike A:
There is a design flaw on Pole Position boards. The power distribution is uneven I guess because of the physical size of the boards. More power gets dumped in to compensate. Eventually the edge pins fry. That is what I read so far. |
