unix tex tape from 1980s?

Just wondering ... if anyone happens to have the contents of a Unix TeX
tape (probably not the actual tape :) from the 1980s, could you let me
know? Or any of the other distribution tapes from that era, e.g., those
sent out by Maria Code from Stanford.

Although saildart.org contains a lot of development files, and
tug.org/historic (systems/unix) contains many older individual released
files, like tex.web and mf.web, I haven't found any general
distributions from earlier than about 1989.

ftp://labrea.stanford.edu is apparently unreachable now, but I don't
remember there being 1980s-vintage stuff there either.

Thanks,
Karl
