I adapted Tim Newsham's v6 install scripts for PWB if you'd
like to run it on simh.

Thanks, very helpful and worked well. Since I was able to
follow the setup script and rebuild the c versions of nroff/troff
on PWB 1.0, I took a look at the new c compiler for differences
with the UNSW copy.
It turns out that the UNSW copy of the c compiler was definitely
a earlier version than in PWB. The most noticeable difference in
the UNSW stdio library was calloc.c not using malloc. The most
major omission in the c compiler was casts and there were also
some local changes to cc.c. Based on those differences, I'm
thinking that the UNSW copy appears to be from late 1976 to early
1977.
I was able to rebuild both the UNSW and the native PWB compiler
on PWB 1.0, but not to backport either to vanilla v6.
Best,
Dan
