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.
