Thanks to Rick Kennedy  of Great Games Plus, Inc. for providing me a copy of the wiring schematics


Notes:

* There are 2 versions of Rampart:
    - 2 player version that is straight JAMMA and uses 
      joysticks to move pieces
    - 3 player version that uses trackballs to move pieces.

* Both version have all options set from the test screen

* In chatting with folks, game play of the 3 player version is much nicer
  than the 2 player version (game rocks, BTW)
  
* I believe that the Rotate buttons double as start buttons for the
  3 player version
  
* The following pinouts are for the 3 player version

For reference, Rampart uses the following pinouts to a standard Wico-style trackball:

1   Gnd
2   +5V DC
3   X Clock
4   X Direction
5   Y Direction
6   Y Clock

If you wire up a trackball and find that one of the directions is reversed, swap the Clock and Direction leads
