Williams Diagnostic Input Adapter DB-06-010

This is a small press-fit board that attaches to Williams System 3 thru 11 CPU boards to act as the Auto Up,  Advance and Memory Protect swtiches. In stock and ready to ship. Pricing is $6.00 plus shipping. Shipping is $2.00 if this is all you order, if you order it in conjunction with anything else I can toss it in for no additional shipping. (still have to pay shipping on the other item(s) though). If interested, drop me an e-mail

Instructions: To install, simply press-fit the board onto connector 1J4 on your CPU board.  No wiring harness needed. Left side switch is for the memory-protect switch at your coin door. Center button is the 'Advance' button on your coin door. Right side switch is the "Auto-Up / Manual Down" Makes life much easier than using alligator clips or other messy wire jumpers.  Stays in place, stays out of the way, and is quick and easy to move through the menus using the advance button.
