I may have something for you:

  -rw-r--r--  1 15 wheel  1,204,371  9 Sep  2009 minix-1.5.10.tar.gz
  -rw-r--r--  1 15 wheel    188,964 10 Sep  2009 minix-extra.tar.gz
  -r--r--r--  1 15 wheel 15,247,252 18 Dec  1994 minix.tar.gz

Don't be put off by the dates of the archives; the programs are mainly
from 1992 and 1993.  They're all on http://www.lemis.com/grog/tmp,
which is not readable.  In particular minix.tar.gz could be useful.
Take a look and let me know; there's more to search.

The programs won't stay there; expect wkt to tell you where the end
up, once we have established exactly what they are.
