Pardon my ignorance, but was a Test Bench, such as the WPC one, something that was able to be constructed using spare boards etc., or were they a specific piece of hardware?

I have a few spare boards, and would be interested to building one if that was at all possible.

 Mine I've built using just standard wpc boards and wiring them up to work on the bench.  You basically need a while pinball machine and cut out the in needed bits ;)

  I almost have enough boards to build a data east test bench aswell
