Williams System 3 to 6 MPU/Driver Board

MPU327 This board replaces both the MPU board AND the Driver board for ALL Williams System 3, 4, and 6 pinball games.

Benefits over original Williams MPU and Driver board

 Eliminates the extremely problematic interconnect connector that fastens the original boards together

 Eliminates the need to swap out game ROMs.  Game ROMs are selectable via DIP switch

 Comprehensive on-board diagnostics using Leon’s test code via DIP switch http://www.flipper-pinball-fan.be/

 Uses 6802 instead of 6800 microprocessor

 Uses a single commercially available oscillator component for timing

 Uses Williams WPC style controlled lamp circuit design (TIP107)

 Uses Logic Level FET drivers for all solenoids and lamp controls

Uses sockets for common failure components (micro, PIAs, and RAM).

 Uses a low voltage reset to keep microprocessor from locking up

This game does use custom software that is NOT compatible with your original game’s board set.

Latest software version is MPU327-BD.

Warranty is void if not installed by professional pinball technician.
