I've wrote an emulator for the KDJ11A (11/73 I think) more than 10 years 
ago before I gave my machine to Grog. It runs RSX11M[+], RT11, v[567], 
2.11BSD at light speed :-) It's on people.freebsd.org/~harti. Compiles 
2.11BSD in less than an hour. It's probably easier than to put up your 
11/73 :-)

About pcc: I've a z8000 based computer with a Unix System III on which 
uses pcc as the system compiler. It's so buggy that I wonder how the 
system even runs. But I suppose these bugs are mostly in the z8000 
backend (no sources to check, though).
