Correct. So if people could stop assuming that an 11/84 have a q-bus, we
would get a long way towards clearing this up.
If people don't know about the 11/84 or 11/94, don't write answers based
on your knowledge of the q-bus based KDJ11 setups.

From my understanding of this after looking at various manuals this is
true for an 11/73 or 11/83 with an H9872 backplane in a BA23 box, but
not for an 11/84. Figure 8-6 in EK-PDP94-MG-001_Sep90.pdf shows a
PDP-11/84-A backplane
with the MDM M7677 in the MDM slot, the KDJ11-BF M8190 in slot 1, a
MSV11-JB/JC M8637-BA/CA in slot 2, and a MLM load module M7556 in slot
3. Not clear to me if the MLM in this case could be replaced by a
second MSV11-J.
Yes. The MLM isn't really neccesary if you have one memory card in there
either, if I remember right. But if you have two memory cards, you don't
have any space left for the load module anyhow.
The 11/94 backplane shown in figure 1-2 in
EK-PDP94-MG-001_Sep90.pdf
shows a KDJ11-E M8981 in slot 1, an APS module M7914 in slot 2, and
slot 3 empty. Does anyone know for certain that this backplane it
compatible with MSV11-J modules, and if so in which slots they would
go?
It's the same backplane. I have an 11/94 box here with an 11/84 cpu and
memory. Works just fine.
Just wish I could land an 11/9x cpu as well. :-)
