MPU327 Rottendog System 3, 4 & 6 CPU board

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
