While this is true, that's not what he's asking.

Sure, the "real" vi and login are owned by AT&T, but most of
the other stuff (tex,gcc,gas) is freely-available via anonymous
ftp (for caltech, the closest archive is probably gatekeeper.dec.com).

A quick check shows 4 vi clones, the BSD version of login, lots
of text stuff, gcc, and gas all available.  I couldn't find metafont.
