A new angle on an old trick.. this board adapts a JAMMA board to a Pacman/ Ms pacman cabinet. The board converts the controls wiring in the existing cabinet to the JAMMA format. 

Also, use an ATX supply if you please.. and don't worry about the green wire, the ATX supply connects directly to the board. If you want to use your own supply, solder your power to the 4 pads supplied. 

You may want to tie the start 1 button to the player button 1, and start 2 to button 2. This allows you to operate a multi-board in the cabinet without further buttons or wiring. You can add a solder blob across the two jumpers on the board if you want this function.

You can also chose which function the PACMAN/MS cabinet TEST SWITCH connects to on the JAMMA board: SERVICE Sw., TILT Sw., or JAMMA Test switch with a simple solder blob...
