I have a question about a JAMMA harness. I want to make a test station so I got a new power supply, new JAMMA harness, new buttons, new joystick, and will be using an old monitor. My main question is, I would like to know the pin out for the player 1 part of the harness. My harness came with a 9 pin molex connector in the middle of player 1 and has terminals at the end to connect to the switches. Without having to check continuity to the board does anyone know the pin out for the 9 pin connector? I found this diagram online but it shows 12 pins and not 9, what am I missing?
