One driver board fits every System 80, 80A and 80B game
Gottlieb used the same solenoid driver board throughout System 80, 80A and 80B, so a known-good board can be swapped into any of these games for testing. Aftermarket boards exist that use MOSFETs instead of the stock MPS-U45/MPS-A13 transistors.
