For several years now, I've been approaching people making pinball test tools to make something like this.
There are other solutions out there, that work OK, but aren't everything I wanted. My test-bench in my workshop is a home-made Sys 3-7 setup, a factory Sys 9/11 test fixture, a factory WPC/WPC-S fixture, and now, a WPC-95 test fixture.
Of the fixtures, only the WPC-95 has a full switch matrix of 8 rows and 8 columns. The Sys 9/11 and WPC fixtures technically will test the entire matrix, but not every switch. Granted, testing with the factory tools will let you know that all the rows/columns work, but I wanted to know that all 64 switches work - and, I wanted a way to simulate multiple closed switches, in a game, in case you needed certain switches triggered to start a game, like multiple ball trough switches.
Every time I'd ask someone, I'd get told that the board would be expensive, and it'd be a fair amount of PCB layout work, and they weren't sure it would sell well enough to make the effort worthwhile!
Finally, after being told no many times, someone said yes. Technically, he said no first, but had a change of heart.
This will work on pretty much every solid state pinball system.

Excuse the DIP switches on my first assembled board, I got them a little crooked :)
