Oh Darn (Re: early PDP-11/45 info sought)

Dang it - the dates fooled me. (blush) Sorry to get your hopes up,
Fritz.
Here is some more accurate information:
The first set:
The first page (the directory) is actually 6/76 in the revisions
block. It is *later* than the one on bitsavers.
Interesting, though: it actually shows TWO directories. One column
is labeled 11/45-1 and the second 11/45-2. It looks like the 2nd
column is for a later CPU, KB11-D.
This set appears to be mostly index pages and chassis/power supply.
The one on Bitsavers includes the KB11-A drawings, which I have as
a separate document (complete with cover).
The KT11-C is actually 12/75
It is *later* than the one on bitsavers.
The KB11-A is actually 4/76
The FP11-B is 7/72 rather than 3/72
THIS IN FACT IS THE ONE ALREADY ON BITSAVERS:
There is a name and "stamp" on the first page that
is quite recognizable, and the dates on my scan
match.
So, I won't rescan it. ;)
The FP11-C is 12/75 as noted [And is not currently on bitsavers]
I will still scan them in except for the one (and the other manuals Noel
identified).
Apologies for the confusion. I was using the date in the date block on
the bottom right of the first page - I didn't notice the revisions block
on the bottom left. 8(
