How Valid's version differed I do not know, but it would have been very small. That basic design, was very popular in the valley. A lot of vendors used it. When Vinod formed VLSI technologies, he got a license. The rest is history as they say. No doubt, it would not have made sense for Valid to keep making it themselves and switched to Sun based HW. I can only say, the original Valid boxes we had at Masscomp (and DEC which should have been identical as we ordered exactly the same thing at the time); we definitely based on the Stanford design. We had them appart in the lab and looked at every aspect of them and they pretty much matched - the drawings Andy used were freely available (IIRC they were in SUDS originally) and many of us had them (I may still for all I know) [we also analized the Imagen and Cisco AGS CPU boards whiich were all based on the same original Stanford design]. ᐧ
