  I'm inclined to think 'microcomputer' meant 'built around a
single chip CPU', eg, like the 8080 et al.  If the CPU was a board,
I'd call it a minicomputer.  Granted, the 5100 was small enough
to easily carry, but a lot happened between 1971 and 1975.  By
'75, as I recall, Wang et al were installing minicomputers running
Basic interpreters in lots of small businesses.

  I recall using Basic over a teletype in the early '60s.  I don't
think it was compiled, however.  Was Basic on the HP-3000 compiled?
If not, what *compiled* Basic was in use by physicists (ie, not just
computer research use) in *1971*?
