Remember.. the *PDT* was supposedly a smart terminal (at least the
11/110 and 11/130 were little more than that)

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...
