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
