8 Liner to JAMMA Adapter

Description

Allows you to play your 8 liner, video slots, video poker or games of similar nature in a JAMMA cabinet or a supergun device.

Games of this type use a somewhat standardized 72 pin edge connector for controls and video and audio output along with a 20 pin power edge connector. These games are also known as Pot of Gold (POG) or Cherry Master type games.

This adapter includes the required 20 pin power connector and wire harness, and features a 12V lamp header along with a control map for providing 8 liner specific functions via the typical JAMMA controls.

Please note that this adapter is not suitable for gambling and redemption environments. The adapter does not provide wiring or headers for payout and complex coin or bill acceptor system functions.
