So...  in the early 1990s I was at a particular small university in Ohio
that had one of the last PDP11/70 running, I believe, RSTS/E in the
state of Ohio (or at least that is what the rumors were and what the
hardware support guy said once).  While I honestly don't remember what
it was used for that PDP11 had a card reader for sure, and something or
other had to be doing the punching (I think I remember watching cards
get run though it once or twice).  I very much suspect that it was the
PDP11 doing the punching, as nothing else at the university could have
done it, unless someone was punching them by hand.  Along with the PDP11
the computer room had a Data General MV10000 and a DG MV4000 neither of
which dealt with cards.  The PDP11/70 was used for the university
administration systems and activities.

I could probably find out how it was used (assuming my memory is not
faulty) if anyone was really interested.
