I think I can help some. I have a PDP-11/45 From U. Wisc. ECE that
claims to be S/N 1525 .
* I do NOT have an actual wire list, it seems, but I will hunt a bit
more tomorrow or Tuesday.
* I DO have earlier PDP-11/45 CPU drawings, but no ECO info
Here is what I have for drawings:

And some diagnostic listings for the 11/40 and 11/45.
I have not looked through my fiche for ECO info, though I am not
hopeful, but will look tomorrow. Most of my fiche are too modern.
Let me know what you want me to scan - should be able to get to it later
this week.

Those reading through the recent "PDP-11/45
RSTS/E boot problem" thread here will know that I've gotten to some corners of my
11/45 CPU now that don't match up with the commonly available engineering drawings.
My /45 is an early serial number (#152). So far I've verified hardware differences
on at least my M8100 and M8105 cards and spares, relating to parity error abort handling.
I would really like to track down any of the following resources:
- PDP 11/45 system engineering drawings *earlier* than those currently available on
bitsavers (Jun '74)
- Any PDP 11/45 backplane wire list (what looks to be a wire list in the currently
available engineering drawings is actually only a breakdown of the power harness.)
- PDP 11/45 ECO information, particularly the following:
M8100 00003
M8103 00005
M8105 00005
M8106 00007, 00008, 00012, 00012A
M8110 00008
KB11-A 00015
Bitsavers seems to have a DEC-O-LOG for M8105, but this does not contain specifics on
cuts and jumps for ECO 00005, referring only to the associated "kit".
DEC-O-LOGs for the other processor boards are missing.
If anybody thinks they might have any of this info squirreled away anywhere, I'd
really love to find out more about it!
Parts of the ECO's are pretty easy to figure, just by comparing the state of my
existing boards to the '74 drawings. But other parts not so much...
thanks much,
