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

That was the plan. I found that the 11/130 I have runs RT-11 quite
nicely and it's the fastest of the tu58 based systems (uses an oddball
parallel interface tu58).

<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...

Think of it as more flexible... runnin for the door. ;)

Seriously the hardware boys seemed to be just a touch off center for the
realm. Even the VT180, a very good CPM engine design they left off
two sided (rev-H has it but I've never seen a real one) and that crippled
disk expansion to the denser two sided media.
