FAQ:
Q: What do you need to connect a JAMMA harness?
A: First thing you need is a JAMMA harness. This is a standard edge connector with two rows of 28 pins used on almost all arcade machines. Physically push the connector onto your JAMMA board. The connector and board are usually ‘keyed’ at the place where pin 7 would be, so that they will only go on one way.
Q: What kind of pinout does a JAMMA board have?
A: The most important and influential of these new standards was the pcb standard pinout. Any game pcb complying with that pinout standard is what we now call a JAMMA board.
Q: How does the JAMMA PCB and edge connector pinout work?
A: And, it is the JAMMA standard pcb pinout (charted below) that has made it all possible. The following JAMMA pinout chart is basically a map of the JAMMA wiring harness 56-pin edge connector. When properly seated to the pcb, the connectors of the edge connector will align with the pinout fingers of the pcb, and your game will play.
Q: How to tell which way around a JAMMA connector goes?
A: One way to tell which way around the connector goes is to locate the wires for the power supply as these will have different terminals to the wires for the controls; the JAMMA board will usually have the pinouts labelled if there is no key. The cables for the power supply will go to the left of the keyslot on the board.
