Ditto.

Running a full UNIX on it was not really possible
although a few of the
Unix style utilities were moved to it and a number of simple monitors were
written that swapped programs in and out DOS style. At one time, I had a
fairly good version of the Bourne (V7) syntax shell we got running, but it
had to be swapped in and out slowly. That is; you run the shell, type a
command, when exec is done, the shell is tossed out and the new program
installed in memory.
One would have better luck with the Apple IIgs except I don't think
there's a good free C compiler for 65816. There's GNO which is very BSD,
but obviously cut back for the necessity of running on top of GS/OS (and
the shell is written in asm, it's not a true Bourne shell AFAIK).
