Rampart Atari 1991 typed up by: Ray Ghanbari 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 Solder Side | Parts Side ________________________________|___________________________________ GND | A | 1 | GND ----------------------------|---|---|------------------------------- GND | B | 2 | GND ----------------------------|---|---|------------------------------- +5 | C | 3 | +5 ----------------------------|---|---|------------------------------- +5 | D | 4 | +5 ----------------------------|---|---|------------------------------- -5 | E | 5 | -5 ----------------------------|---|---|------------------------------- +12 | F | 6 | +12 ----------------------------|---|---|------------------------------- - KEY - | H | 7 | - KEY - ----------------------------|---|---|------------------------------- Coin Counter # 2 | J | 8 | Coin Counter # 1 ----------------------------|---|---|------------------------------- Lock Out Coil # 2 | K | 9 | Lock Out Coin # 2 ----------------------------|---|---|------------------------------- Speaker (-) | L | 10| Speaker (+) ----------------------------|---|---|------------------------------- | M | 11| ----------------------------|---|---|------------------------------- Video Green | N | 12| Video Red ----------------------------|---|---|------------------------------- Video Sync | P | 13| Video Blue ----------------------------|---|---|------------------------------- Service Switch | R | 14| Video GND ----------------------------|---|---|------------------------------- Tilt Switch | S | 15| Test Switch ----------------------------|---|---|------------------------------- Coin Switch # 2 | T | 16| Coin Switch # 1 ----------------------------|---|---|------------------------------- C Rotate | U | 17| L Rotate ----------------------------|---|---|------------------------------- C X Dir | V | 18| L X Dir ----------------------------|---|---|------------------------------- C X Clk | W | 19| L X Clk ----------------------------|---|---|------------------------------- C Y Dir | X | 20| L Y Dir ----------------------------|---|---|------------------------------- C Y Clk | Y | 21| L Y Clk ----------------------------|---|---|------------------------------- C Fire | Z | 22| L Fire ----------------------------|---|---|------------------------------- R Fire | a | 23| R Rotate ----------------------------|---|---|------------------------------- Spare | b | 24| Spare ----------------------------|---|---|------------------------------- R X Dir | c | 25| R Y Dir ----------------------------|---|---|------------------------------- R X Clk | d | 26| R Y Clk ----------------------------|---|---|------------------------------- GND | e | 27| GND ----------------------------|---|---|------------------------------- GND | f | 28| GND -------------------------------------------------------------------- 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
