Tehkan to JAMMA Adapter

Description

Allows you to use your Tehkan classic pre-JAMMA game, in a JAMMA cabinet or a super gun device.

Before they became Tecmo later in the decade, Tehkan produced many successful arcade games in the the 1980s. Just like many arcade game manufacturers from this period, their games shared similar hardware and pinout configuration.

One of the more unique feature of this pinout class, is the separate 6 pin, single row 2.54mm pin header for video. Some bootleg boards use a 5 pin connector on the PCB with a shroud around the pins. The video header is typically on the opposite end of the board in relation to the edge connector.

This adapter includes a 5+1 pin cable that can be used in both genuine 6 pin Tehkan and 5 pin bootleg pcb variants and is 40cm long, that should be long enough for all boards.
