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.
CDC was just an early adopter of the idea that a front panel involving a
keyboard and display are more user-friendly and more powerful than a
vast number of lights and switches.
