Rampart, Atari 1991
------------------
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
