JAMMA to Tehkan Cabinet Adapter

Description

Allows you to play your JAMMA games in a cabinet wired according to the Tehkan 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.

Compatible Cabinets

This is the list of compatible cabinets that can be used with this adapter:

* These games’s pinouts swap the start and coin switch location.¬†Jumpers on the adapters change the function of these pins accordingly for compatibility with these game.

Important: Your JAMMA game will not work correctly if it requires -5V power, not normally available in Tehkan cabinets.

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 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.
