Williams System 9, 11, 11A, 11B and 11C MPU Board
Rottendog's Williams System 9, 11, 11A, 11B and 11C MPU Board is completely redesigned and replaces the MPU board in all Williams System 9 through 11B games, INCLUDING System 9-11 early games such as Comet and High Speed.
This completely redesigned board
replaces the MPU board in all Williams System 9 through 11B games, NOW
INCLUDING System 9-11 early games such as Comet and High Speed, view the
full list below.
- This new board has a small balancing pot to compensate for the differences in volume on the MPU and soundboard.
- For System 9 games, the external sound board is not longer needed and is incorporated in the new MPU board.
- Custom EPROMs are required for the System 9 games, which you can order below.
- For all games, you must move over your (2) 6802 processors or buy here.
- For System 11 games, you will need to swap over your two Game EPROMS from your MPU board and the two Sound EPROMs from the Sound board or buy them here.
- All 6821s chips are provided, and the MPU9211 comes with NVRAM installed, no batteries are needed!
Benefits over the original Williams board:
– Williams WPC type mounting holes for ease of install / uninstall.
– No batteries required for memory retention (no alkaline damage, ever!)
– Simplified driver design using logic level FETs
– Beefed up switch matrix drive for better durability (good to 100V back drive)
– Board is made with 100% through-hole components.
– No custom parts used in this design (all parts can be purchased through usual suspects)
– Major component designations carried over from original design so original schematics can be used.
– Board schematics available on request.
We have, from time-to-time, rebuilt MPU9211s available at a discount! These are fully tested with our shop's 90 day warranty.
