PDP 11/70s For Sale - test-drb@ccmp.vtda.org

...
 I seem to remember it being in a Terminals/Comms
handbook (which I can't 
find at the moment :-(), where it claimed that the PDT11 was _not_ a 
PDP11, since it didn't have a Unibus/Qbus on it. 
Remember.. the *PDT* was supposedly a smart terminal (at least the
11/110 and 11/130 were little more than that)

...
 The PDP11 Architecture Handbook is inconsistent. It
describes the 'Two 
PDP11 Expansion Buses' but also calls the PRO300-series 'A PDP11 family 
member'. 
It is a member simply by virtue of the fact that the CPU is the same
architecture.  Nothing that was done in the PRO precluded that... it
just took a little more programming to control anything since you had
to program the interrupt controller...
