Eric,
You hit the head right on the nail ;-) All kidding aside, that is exactly it!
thanks to all for your input.

I have now retyped everyting from this document (24 pages in Courier 10 pkt) and scanned the tables etc, in total 7 MB after ZIP.
The material is now on its way to Fred, so he can convert it to PDF format.
It could be interesting to hear the comments of someone involved in the original ES project, so we can see how close the CIA was with regard to the project.

What's the problem with you guys??? The Unibus is really simple to get
right. :-)
One thing you should know about the 11/84 is that you don't use wire wraps
on the backplane for the NPG slots in the CPU box.
The M7677 (MDM) have NPG switches for all card slots instead. Go to that
card and check it out...
Second. The 11/84 must have a minimum load on both the PMI and Unibus. The
minimum load module (MLM) is M7556. Since you have two memory cards, that
MLM is not in. But depending on the configuration of the Unibus, you might
want to have the MLM in there. However, I don't think you have a problem
here, since I suspect that if the machine powers up, that aspect is ok.
It would be nice to hear how Gunther is doing. I'm very sporadic on
classiccmp though. If you need help on pdp-11 stuff, I'd recommend you
post to info-pdp11, or alt.sys.pdp-11 (or whatever it's called).

---------------------------------
I am having a similar problem, but my system does not have an M7677.
Mine is an 11/84E. The CPU is in slot 1, memory cards in slots 2 and
3, and the Unibus adaptor in slot 4. 5 and 6 are empty, 7 and 8 have
the UDA50, and 9 has a printer card of some sort. For mine the NPG
grant jumpers are actually on the bottom of the backplane. I have set
them for where the boards are not.
I had believed this system to be configured as working, but it is not.
It has a second backplane but had no M9202. If I put the terminator
in slot 9 of the primary backplane it hangs. I know the UDA50 needs
the NPG out. I will have to examine to see if the printer card needs
it or not. I would guess the Unibus adaptor would not?
