JAMMA to Irem Cabinet Adapter

Regular price $19.00 USD
Regular price Sale price $19.00 USD
Sale Sold out

Allows you to play your JAMMA games in a cabinet wired according to the Irem classic pinout class.

Please confirm the power requirements of your game and that the pinout matches the wiring of your cabinet in the relevant sections below. This is especially important for cabinets that have less than 2 buttons and only one coin switch.

Voltages

This adapter does not connect the -5V rail, not normally available in Irem cabinets. Your JAMMA game may not work correctly if it requires -5V power.

Inputs and Outputs

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 2 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 works, you may need to run a jumper from button 2 to button 1 at the cabinet wire harness edge connector.

If the 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.
