As far as I know, all the FP11 models:

  https://gunkies.org/wiki/FP11_floating_point

are program compatible. They are, of course, internally quite different, and
do not share an interface to the rest of the CPU (except for the KEF11-A and
FPF11; but they are of course both used with the KDF11 CPUs).


I compared my hard-copy of the "FP11-C floating-point processor user's
manual" (EK-FP11C-OP-001 - the one being searched for) with the "FP11-C
floating-point processor maintenance manual" (EK-FP11C-MM-001), which we have:

  https://www.bitsavers.org/pdf/dec/pdp11/1170/EK-FP11C-MM-01_FP11C_May76.pdf

and they appear to be identical up through to the end of Chapter 5 - the end
of the FP11-C user's manual. So we basically have the 'FP11-C user's manual'.
