Until I got to the punch line, I was sure you were going to say "CDC 6600,"
which was the first of that series of machines.  I'm at home and can't lay
my hands on Thornton's book ("Design of the CDC 6600" I think was the title),
and I didn't actually use a 6600 until 1970, but it seems like you would have
to say 6600, or at least 7600, to make the "more than 20 years" accurate.
