    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
    - 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.
