I have 6 of these it total at the time of listing

Taken from a working game many many years ago and just brought out of storage and tested (24 hr soak)

In addition I have carried out all tests to ensure that this is correctly working

If you have a faulty board, please make sure you test your power supply before fitting a replacement unit - the power supply voltages being out of range on the high side will damage your new board if not set correctly - if unsure please check with someone who knows how to do this, and please test as close to the game board as possible, not at the power supply (ie at the jst connectors where possible)

These boards are typically used in driving games to connect multiple boards together for multi-player configurations and also on Virtua On 2
