Now that makes a lot more sense.
So PMI memory choice is: (2 Max)
MSV11-JD M8637-D 1 MB ECC PDP-11/84 or PDP-11/83
MSV11-JE M8637-E 2 MB ECC PDP-11/84 or PDP-11/83
The CPU choice is:
Module Type Speed RAM ROM LTC SLU
------ ---- ----- --- --- --- ---
M8190 KDJ11-B
M8190-AD KDJ11-BA 18
M8190-AB KDJ11-BB 15 0 Y Yes
2
M8190-AC KDJ11-BD
M8190-AZ KDJ11-BF 18 0 Y Yes
2
So.....
1. Plug in one or two memory cards.
2. Plug in a CPU card
3. Insert Bus Grant cards (Which end of the slot?)
4. Insert in Slot nine a M9302 UNIBUS TERMINATOR and a M9713 MIN. LOAD
MODULE
5. Now we would have:
Slot 1 M8190-Ax KDJ11-Bx 11/83 - 11/84 CPU Card
Slot 2 M8637-X MSV11-Jx PMI Memory
Slot 3 M8637-X MSV11-Jx PMI Memory
Slot 4 M8191 KTJ11-B Unibus controller
Slot 5 M7547 TUK50-BB Tape controller (Bus grant as
well?)
Slot 7 G7273 NPG and BUS Grant
/ Double Grant
Slot 8 G7273 NPG and BUS Grant
/ Double Grant
Slot 9 M9302 UNIBUS TERMINATOR
Slot 9 M9713 MIN. LOAD MODULE
6. Connect up a terminal (I have several 420's) to the SLU connector.
7. Connect a TK50 drive (Which I have) to its controller.
8. Check for correct boot proms on the CPU card.
9. Switch on. Wait for smoke to clear. Look for output on the terminal.
10. Insert a bootable tape. (Which I don't have yet)
All those in favor of this config say Aye!
All those against email me quick, before I do anything dangerous!!

Well I think I understand the list.
But for clarity's sake here's the problem again.
1. I have a number of PDP-11/94's
2. The first three slots are Quad Qbus 3. The missing KDJ11-EB would
have been in slot one 4. Slot two has a M9714 ALT PWR FOR KDJ11-E in
it.
5 Slot three is empty.
6. Slot four is a Unibus slot and has a M8191 KTJ11-B Unibus
controller in it
7 Slot five has a M7547 TUK50-BB Tape controller in it.
8. Slot's Six,seven and eight are empty 9. Slot nine has a M9302
(UNIBUS TERMINATOR) at one end and a M9713 (MIN. LOAD MODULE) at the
other.

Sorry, but your options are very few.
The first three slots of that backplane are not Q-bus, but a special
adaptation of it for the PMI memory and nothing else. You cannot use
Q-bus memory on it, and no other Q-bus options either (atleast according
to the manuals, I haven't tried in real life. I could check out if any
signals differ, if it were real important).
Second, the Unibus adapter required some special signals from the
CPU-board as well.
Your options are basically the 11/8x and 11/9x CPU boards. No others
will originate the signals for the Unibus adapter required. Memory wise
only PMI memory boards will do.
For an 11/94, all memory are on the CPU board, so for those, the two PMI
slots should always be empty.
To make the power supply happy, you normally have some bus loads on
them.
If you go for the 11/84 instead, you also need to find PMI memory
boards.
That's the CPU/memory part of your system. You then need to configure
the Unibus correctly, which means you need unibus grant cards in
theright place of all empty slots. You probably also want some disk
controller in that system.

I am not absolutely positive, BUT the probability is VERY
high that the above two PMI memory boards are ONLY for the
Qbus. I believe that you must use either the MSV11-JB or
the MSV11-JC within the PDP-11/84 system.
It is probably confusing, but the CPU is the KDJ11-BF which
is used in BOTH the PDP-11/83 (which I have and the memory
used is the MSV11-JD or the MSV11-JE) and the PDP-11/84
which you have. If you can find a KDJ11-BF along with two
MSV11-JC PMI memory boards, the cost will likely be much
less than a PDP-11/94 CPU.
Sincerely yours,

Good to know. Can anyone else confirm having used
either the
MSV11-JD or the MSV11-JE with a PDP-11/84 system?
I have read the opposite, but I certainly bow to your much more
extensive hardware experience. However, have you ever actually used
an MSV11-JE board in a PDP-11/84 system?
No, I've used an 11/84 but never owned one nor taken one apart. But
it's in plenty of documentation, like for example the MSV11-J manual,
the relevant Micronote about memories for microPDP-11s, the 11/84
Technical and Reference Manual, and several entries in the DECUServe
archives.
