    > the first DEC machine with an IC processor was the -11/20, in 1970

Clem has reminded me that the first was the PDP-8/I-L (the second was a
cost-reduced version of the -I), from. The later, and much more common,
PDP-8/E-F-M, were contemporaneous with the -11/20.

Oh well, only two years; doesn't really affect my main point. Just about
'blink and you'll miss them'!
