I just bought a Gorgar project that is in excellent condition, however the CPU LED's keep flashing and all the coins on the playfield turn on/off/on/off/on/off......

I think it is a driver board issue, perhaps in the 40 pin connector..?  any suggestions?

thanks.

It sounds like the machine may have Leon's test ROM installed:

The instructions on his page explain how to use the ROM to test the CPU and driver board. Intended for use on the workbench, not in the machine.
