That's the approach I took. We do 100% testing, so speed of test
directly impacts cost. After designing several testers for various
products, I developed a "generic" tester consisting of various modules
like ADC, DAC, relays, buffers, etc. These modules plug into a
motherboard of sorts (controlled by a PIC of course). 

I'm not sure what size picture I can post, so I'll try a separate post
with a picture of the bed of nails with hinged cover.
