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(
