MILLIPEDE --------- The following is edited version of the Millipede pinout listing originally done by Jonathan Deitch. This version adds the pinouts used for a cocktail style cabinet, joystick inputs, and seperate H & V sync outputs. This additional information was shown on the pinout sheet which I got from Video Connections. I'd strongly suggest verifying these before you use them.
