LCS ran a pdp-11/45 in 1974 that was used to teach lisp. I don't believe it ran unix, but it definitely was multi-user.

  I think it was probably RSTS/E. There were other pdp-11s like the KTV or XGP machines. There might have been Unix machines someplace (MIT is a big place) I just meant that never saw any, and in particular around where quux was assembling the jargon file.

    Nope. It ran an in-house OS named "Delphi". There was a PDP 11/45 at LCS and a PDP 11/40 in building 38 used to teach 6.031 (the predecessor of 6.001).

      Is there any information available about this "Delphi" OS? I've always found obscure historical operating systems fascinating.
