7/20/2017 newly revised MPU327 with support for Black Knight! This board replaces both the MPU AND Driver board for ALL Williams System 3, 4, 6 and 7 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
  • 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 single shot (70ms) for Special Solenoids (no more burned board due to shorted contacts
  • Uses sockets for comon failure components (micro, PIA 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. Software may be modified over time and will be made available online.
