Hi Everyone,While I'm still developing my ideal pinball troubleshooting board for your Williams system 3 through 7 pinball machines, I have come up with an intermediate solution for those who need to get their machines up and running today.
It's called the Pincoder Adapter, it comes preloaded with the Pincoder diagnostic software, and is ready to go out of the box. You do not need a chip programmer or any chips to use it.
You can find out more and also purchase the adapter here:

The Williams built-in code has been known to produce false positives because it only tests chips on a few addresses to see if it responds.
There is even a switch bounce test that allows you to find switches that produce more than one pulse per acti vation - typically due to dirty or worn contacts. Completing this test is good for ensuring accurate scoring.
