The mtXinu 4.3+NFS I used in the late '80s used DES-based password
hashing.  Enigma-style encryption was present as crypt(1), but crypt(3)
was quite definitely salted-mutant-DES.  SunOS of the same era also
used the same mutant-DES algorithm, but I have no memories to say just
how far back this was true.

I *think* this was also true of 4.2; until now I'd've assumed it was
also true of 4.1c before it, but that was an assumption - I can't
recall ever looking at the password handling code under 4.1c.
