UW did have its own mainframe for business operations -- a Burroughs.
It was used for *nothing* else. The CDC was the academic-side big
computer.

IBMs were leased. Would IBM continue to support a computer that had
some academics' experimental hardware hooked up to it? Could new and
experimental device drivers be added to IBM's OS? These might be as
important as the machine's architecture.

The National Enquirer just makes stuff up for (dubious) entertainment
value. Datamation didn't. Datamation just concentrated on the
corporate data processing market, where IBM did indeed dominate. But
the academic and research markets were a lot more fun and interesting,
and they were dominated by PDP-10s.

Well post anti-trust they had too. And I know certainly in the UK, we had
lots of weird kit hooked into various University mainframes using a wide
variety of interfaces. The oldest I remember NUNET/NUMAC (I think) used
PDP/11s acting as IBM2708/3708 concentrators. There were "Browns Boxes" for
X.25 and some how Cambridge Ring got connected in at Leeds but I think that
was actually an Amdahl at that time...

I guess I wasn't clear. Suppose that IBM was willing
to supply machines with roughly the same performance
as a PDP-10, under the same terms and conditions as
DEC would. And assume the machines would be given to
the CS department where they would be available to
the students and researchers under the same conditions.
