Correct. And the T11 is running RT-11. The console card in the cpu holds the
T11 and the q-bus comes out on cables on the rear. The card itself sits on the
same backplane as the rest of the VAX. And that is called the A-bus. You then
have one or two SBI adapters on the A-bus, and memory is also there. So, no SBI
transaction for the VAX cpu to access memory. And the T11 have local memory on
its card. The q-bus then sits in the same box as the first unibus. So that one
BA-11 is a bit special in that it holds both a q-bus and an unibus. And the
RL02 is located above that BA-11. I have a bunch of docs, but I think most of
it is also available online. But I can test as well as check things on the real
machine whenever I'm near it. I have both VMS, Ultrix and NetBSD running on it.
Just select the right boot script...
