First which of the many versions of 2.9bsd do you have? The original Berekely
code or the code as modified by Harvard and The Center for Seismic Studies
(sometimes referred to as the CSS version) or the CSS version as modified 
here at Oswego? We don't have a PDP-11/84 so I can't say that we've run
any of the 2.9's on one, but since the 84 is supposed to be a 73 with a
Q-bus to Unibus converter on it, I'd guess that the processor type of
PDP-11/70 might be the correct option. 

If you could get back with which version you are running, our Systems
Programmer, Paul Taylor may be able to help you. His address is
