If you want

zit doesn't support the -11/03 'out of

shouldn't be too hard. (Heinz mentioned that
it had been done
before.)
On thinking about it, I might do the -11/03 port of Mini-Unix for the hack
value; it looks like it should be a quick project (a couple of hours, much
of
which would be getting Mini-Unix set up; I'd use a simulator, my QBUS RK11
emulator is broken at the moment).
I think it should mostly just be some fairly straight-forward changes to
mch.s; I think all the C code would be fine. (Unless there's an
'PS->integ' or
something hiding somewhere.) Also a few odds and ends, like a software
console
switch register (been there, done that).
That would make the full power of Mini-Unix available to people with
-11/03's;
those are still fairly common, and reasonably cheap. (Unlike -11/05's.)
It's a
considerably more capable system than LSX: e.g. the tty driver is the full
V6
one, and supports an arbitrary number of devices.
So my question is: had anyone else already done this (I don't want to waste
time replicating already-done work)? Also, would anyone have a use for it
if I
did it? If so, I'll put it up on a Web page when I'm done. (No, I _don't_
use
Guthub, and have zero interest in learning how. I'd rather spend my
remaining
un-comitted neurons improving my ability to read feudal Japanese.)
There's several references to different miniunix patches in the AUSAM
newletters... Any chance those are still around? They don't seem to be in
the TUHS AUSAM archives, though...
