Including the NFS 2.0 sources that Warren currently has in the TUHS
archives ;)

Towards the end, they were using BSD 4.3 on Vaxen - I even got my hands
on a couple of 750's, which have been ruined over the years because of
environmental problems with the storage location. I do still have a
complete set of boards.

I still have an RM05 pack, labeled /pix ... probably way past the
ability to be read, I'm afraid, unless someone wants to sacrifice an
RM05 drive to try.
