early PDP-11/45 info sought

[Jay Jaeger]

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:

    M8104, M8105, M8106, M8109, M8116, M930, M9202]
   NO wire list

(Curiously, I also have KB11-C, 11/70 drawings.)

B-DD-MF11-U-B 16K Core [M8293, G235, G114, H217, M7259 (Parity Control)]

PDP-11 Systems Course Training Drawings
PDP-11/45, 11/70 Maintenance Course handout book

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.
