I put together a quick list on identifying Irem M-92 boards. If anyone has a board that isn't using the M92 hardware and needs hel identifying the board then please visit the System 16 Arcade Museum.
Lot's of useful info on just about any arcade hardware ever made. If the site helps you out feel free to donate. It's not my site obviously but a great resource tool and should be supported.
