Roger that!!
The other bus grand card is two connectors high, and
also carry the
NPG line, in which case you don't need to worry about the
DIP-switches.
These I have so where do they go?
Thanks for the kind assistance Jonny.
There now follows a general request for:
One M8190-Ax KDJ11-Bx 11/84 version
One/Two M8637-D or -E MSV11-Jx 11/84 version.
Anybody having or knowing the whereabouts of the above modules please
email me at:

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
Correct.
The CPU choice is:
Module Type Speed RAM ROM LTC
SLU

You need to check out if all of these really works in an 11/84. I don't
think they all do. Some had hardware bugs that meant they only work in
the 11/83 configuration.
So.....
1. Plug in one or two memory cards.
Yes.
2. Plug in a CPU card
Yes.
3. Insert Bus Grant cards (Which end of the slot?)
The bus grant goes into the middle slots. There are two models. One
really small one, which is only one connector high. They should go into
the fourth slot from the top if my memory serves me right. In this case,
you also need to make sure the NPG lines are are connected. This is done
by a DIP-switch block on the backplane. One switch per slot. It should
be visible if you look down into the cage. The other bus grand card is
two connectors high, and also carry the NPG line, in which case you
don't need to worry about the DIP-switches.
4. Insert in Slot nine a M9302 UNIBUS TERMINATOR and a
M9713 MIN. LOAD
MODULE
Yes.
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
You only need one memory card, so it's not really neccesary to get two.
Also, no grant in the slot where you have the TUK50. But I'm missing a
grant in slot 6. :-)
6. Connect up a terminal (I have several 420's) to
the SLU connector.
Yes.
7. Connect a TK50 drive (Which I have) to its
controller.
Yes.
8. Check for correct boot proms on the CPU card.
No need, normally. The 11/8x and 11/9x cards have nice large boot proms
with all kind of boot routines on them, including booting from TMSCP.
9. Switch on. Wait for smoke to clear. Look for output
on the
terminal.
Yes.
10. Insert a bootable tape. (Which I don't have
yet)
That would help if you don't feel like starting to write your own code.
But for test purposes, not needed at all.
All those in favor of this config say Aye!
All those against email me quick, before I do anything dangerous!!
If you're just interested in checking that the machine is working, skip
the TUK50. Just make sure the unibus is "whole", and fire her up. The
boot monitor of the 11/8x and 11/9x are real talkative, with lots of
things that can be done without anything else, including running tests,
and checking out the hardware.
