Would SCO->Caldera have copies of this? SCO did the Intel port of Xenix
so they would probably have started with the PDP source. Would tapes be
copyright to Microsoft?

I doubt that they would release the source for the Intel version as it
is still in use today although I don't think that SCO/Caldera will sell
it anymore.
