Sega System 8 to JAMMA Adapter

Description

Allows you to use your pre-JAMMA Sega System 1 and 2 games, in a JAMMA cabinet or a super gun device.

This 8-bit hardware predates System 16 boards and was used from about 1983 to 1987 not only by Sega but also other manufacturers such as CoreLand and Vic Tokai. System 1 boards are typically older and consist of a single PCB while System 2 boards are typically larger and consist of 2 PCBs stacked together. Both types share the same pinout and belong to a pinout class commonly known as Sega System 8.
