JAMMA to Namco (Galaga) Cabinet Adapter

Description

Allows you to play your JAMMA game in a Namco Galaga or a pinout compatible game cabinet.

This pinout has 3 connectors in total, a 44 pin edge connector for controls, switches and sound, one 3 ping plug for power, and another 6 pin plug for video. All have to be plugged in for the conversion to work correctly.

Check the pinout, controls and power section below, to ensure compatibility especially for cabinets with only one button, one coin switch or when using a JAMMA game that requires -5V power.

(adapter edge connector facing away, list is ordered right to left)

In addition, this adapter has the typical Namco 63080 type male power and video connectors.

* Bootleg video not supported on this adapter due to known conflicts with some games. Lamps are not used.

Important: Games that require -5V to operate, will not work correctly due to -5V power not being available in Namco 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.
