Williams System 3 to 7 Pinball MPU Board from Kohout Enterprises. This board is Brand New, Unused and recently purchased.. I installed this board in my Gorgar Pinball Machine to confirm testing. 100% working. Guaranteed. Free Shipping. If you cannot swap over your EPROMS to the new board they can be provided. Just let me know what game.

I do have a brand new Driver board also with the ribbon cable connection. If you would like both boards bid $325.00. The cost for both boards new from their website is $425.00. These boards are brand new, recent purchases I made.

Below is description of the MPU board from their website.

This is a drop in replacement for all Williams System 3 to 7 pinball and shuffle bowler games. Like all the other Kohout Enterprises’ boards, obsolete components have been designed out, when possible, and up to date devices are used. The board includes a 30 day unconditional guarantee and a 1 year repair/replacement warranty.

Some Improvements to the original are as follows:

No Battery Backup required – Preferred option uses Ramtron FerroRAM which does not require a battery to save data. As long as we have stock, these will be installed.
Added 40-pin connector for Replacement Main Driver Board – A standard 40-pin IDE connector has been added to bypass the large, problematic molex connector.
Simple Diagnostic LED’s added for troubleshooting – 9 LED’s were added to check the critical signals on the board to be able to troubleshoot simple problems with the board.
Simple jumpers to allow many different configurations of EEPROMs – 2532 or 2732 EEPROMs can be used and Williams supplied Firepower EEPROM code requires only a jumper change.
Clearly labeled Jumper Setting and components are silk screened on the board for easy identification.
Difficult to find IC’s have been designed out and replaced with components that are currently available from multiple sources.
Thicker PCB for improved durability – 0.093? instead of 0.063?
Each board comes complete with the replacement board, schematics, board layout drawings, instructions, and one EEPROM set to the game of your choice.

NOTE: When ordering the Main and Driver board “combo”, the 40 pin molex connectors will not be installed. They will be replaced by a 40 pin IDE cable.
