It probably wouldn't have helped to preserve the code.  At CDC, source
code control started rather early in the 1960s, so there was lots of
tape with millions of lines of source code hanging about in rack after
rack of tapes.

Other than the stuff in private collections, I doubt that much of any of
it has survived.    When I left CDC, I was told to turn in any tapes or
copies of software that I had in my possession, as much of the work was

Other than the stuff that made its way to university collections
(nothing that I ever worked on, obviously), it's all gone as far as I
know.   Even the documentation for much of it, since that also was
