Rottendog is the manufacturer of replacement boards for your pinball machine.

Williams System 3-6 MPU / Driver - MPU327

MPU327- This board replaces both the MPU board AND the Driver board for ALL Williams System 3, 4, 6 &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 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.
Updates to this software will, I'm sure, be modified over time and updates will be made available though this web site.

Williams System 7&9 AN Display Set - DIS079

DIS079 - These boards are replacement LED displays for all Williams System 6a, 7 and 9 pinball games. They are made from an advanced LED technology that was not available when the original boards were made by Williams. We spent quite a bit of time matching the original color and brightness and are quite happy with the results.

Our boards are plug-and-play compatible with the original board set.  No special tools or mounting tricks are required and the swap can be done by even the most novice of "installers".

Benefits over original Williams displays (and other replacement boards):
- No High Voltage Required!  These will operate with a defective +/- 100V power supply
- No Fragile Gas Display!   This light weight LED display should last 10X longer than original displays
- Simple design ( 9 Integrated circuits, NO transistors)
- Through Hole Parts (ask your repair person what this means)
- All integrated components are current technology available from most distributors
- Boards come with complete set of schematics
