Those are good examples, but is it "many" or just those two and maybe one or 
two more?  For example, Burroughs and IBM mainframes were both very much 
"lights and switches" control panel type machines.  For that matter, so were 
the other CDC products; the 6000 series was a bit of an outlier I think.
