Sanwa Denshi G-PIN JAMMA protection insert

A specially shaped plastic insert for the JAMMA edge connector (pin 7), to physically prevent reverse input of the edge connector onto the game board.

Often a reverse input of the edge connector onto a game board will cause electrical damage to the game board and/or the arcade cabinet circuitry. 

This represents a low cost safety device to prevent a mistake that could potentially cost thousands of dollars in damage to game PCBs and/or arcade electricals.
