About 20 years ago, Star Tech Journal (the coin-op equipment repair publication) was manufacturing a Jamma test card. It was inexpensive and you could plug it into any Jamma cabinet to verify power supply, switches, speaker, and monitor wiring was good.
If you were wiring a cabinet from scratch, this would be very helpful in case you made a major error in that you would only damage this cheap card and not an expensive game board.
