I am in need of a Pole Position schematic. Picked one up today and it will power on but the screen is just green. The harness has several wires that are pulled loose. Hopefully I can find where these go and make the repair. Not really sure if I can do it or not but I guess its worth a try.
 
Hi,
I load down this schematics but they don't fit on some subjects. With my sit down cab.
1. Power supply is different (Interessting point, the BridgeRectifier mounted downside has no connection to GND)
2. The Fuses are not upside mounted they are capsulated.
3. No one of the wire colours fits.
4. On my PCB Board is written -21 ? Don't know what this means.
5. Have more Eproms above the 4 10xx ICs. (Do I have a PPII Board ?)
I Googled many hours but I din't find another version. Am I to silly or is there no different schematic.

Thanks for hints.
Walter

I did some research back in the day and found that they has 8 different revisions of the schematic. (no joke)
