As the author of both LSX and Mini-UNIX, I would suggest that the
LSX source code is a better starting point for the 11/04, especially
if single-user is the target. Mini-UNIX was written to support a
small number of users on the PDP 11/10 without an MMU.
However, I'm not current on what sources are still available.
