Part Number DMD089

Williams / Bally WPC89 / WPC-S DMD Driver Board

DMD089 - Dot Matrix Driver Board compatible with Williams WPC89 and WPC-S pinball games.  The board that this replaces is Bally / Williams part numbers A-14039 (all versions).

This board is a direct plug in replacement for the original OEM driver board.  

The high voltages produced by this board are nominally set for -110V, -100V and +64V.  These voltages can be adjusted but you would need to change resistor values!

Key Benefits

- Redesigned / simplified high voltage section which eliminates high temperature circuit board burn.  This board will NOT burn up the way the original board does!

- LEDs added for visual verification of +5VDC

- Test point locations centralized into one location and clearly marked for easier troubleshooting

- All new (not 25+ year old) components and PCB
