- There's a 'Unix' for the LSI-11, and with = minor changes (the LSI-11 isn't
100% compatible with other = MMU-less 11's, but the changes are minor, e.g.
MOS, = written in MACRO-11, was conditionalized to run on both the LSI-11
and the -11/20) it should run on an /04.

We ran that on = our MMU-less PDP-11/20s and 11/40 before the LSI-11 was even = introduced.
It lacks obviously memory protection, = traditional UNIX pipes (they=E2=80=99re simulated by the shell if I = recall), and preemptive scheduling.
