Much snippage...

First off 2mhz was a short lived event in s100 world. Also there were
three ssets of basic timing, those from 8080s, 8085s and also the z80s.

Don't forget memory that was CPU specific and pseudo synchronous like MITS
88MCD or S4k or the vector 48k that required Z80 /refresh.

Interesting concept but likely it will not work in my pokey 486DX or the
386sx/16 I have the logic analyser in. I'll still fix more boxes with far
less. My problem often enough was that there were too many times hwere
the new hardware used to facilitate the testing was more suspect and
complex than the target system.

Then again if I were making more than a few hundred a year with minimally
skilled people, automated test is very nice.
