Well, I looked at:
https://gunkies.org/wiki/FP11-C_Floating-Point_Processor
and it lists a user's manual (EK-FP11C-OP-001), but doesn't link to it.
(In general, the CHWiki contains pretty good coverage on PDP-11's - hardware,
I never had much use for DEC software; it should be the first stop for
anyone with PDP-11 hardware questions.)
Searching for that turns up an old email message from me:
https://www.classiccmp.org/pipermail/cctech/2015-September/010265.html
which says that I have a copy, and was planning to scan it. I got sick, and
never got to doing so, alas. And now my scanning machibe has a dead hard
drive.

The FP11-C was program compatible with the FP11-B Floating-Point Processor,
but there isn't a separate FP11-B user's manual; just use the -11/45 or
-11/70 processor manual.
