JAMMA to Konami Cabinet Adapter

Description

Allows you to play your JAMMA games in a cabinet wired according to the Konami classic pinout class. This pinout class is compatible with many Konami games during the 1980’s. See list below.

Please confirm the pinout in the table below matches the wiring of your cabinet. This is especially important for cabinets that do not have -5V power present, have less than 3 buttons and only one coin switch.

Button and Switch Layout:

In most circumstances this adapter will work as intended with your cabinet without any modifications. Problems may occur playing some JAMMA games in a modified cabinet with less than 3 buttons, or only one coin switch present.

If the button order is wrong you may need to swap the wires going to the buttons behind the control panel. If a button doesn’t register at all, say only JAMMA button 2 and 3 work, you may need to run a jumper from button 3 to button 1 at the cabinet wire harness edge connector.

If game can’t be coined up, say in a case where only COIN2 switch is wired in the cabinet, and the game only supports the COIN1 switch, you may need to swap the coin wires on the harness or potentially jumper them together to get the game to coin up.

Voltages

For JAMMA games that require the -5V power, please check if the cabinet has a power supply capable of producing it and that it’s wired correctly according to the pinout above.
