Ed,
be sure to lock your back door: I might sneak in and rip that chip from
your 11/24! ;-) - It seems to be about as common as a cache board (KK11)
for a PDP-11/34A. The latter I have (out of the only PDP-11 I ever paid
for!), but my quest for a CIS chip has not turned up anything in years.
In case you have (or can take) a picture of this chip, I'd appreciate a
link. I assume it is a fairly large ceramic base (to span the pair of
40-pin sockets) with one or more actual chips and perhaps some small
capacitors on top, somewhat similar to the /73 CPU chip, but larger?
Regards,
Andreas

My original reply was just to find out how unusual this chip is, as I have
one here. It is currently stuck on an 11/24 board, occupying socket 4 & 5.

Yes, there sure was a CIS chip for the 11/23[+].
And I am still looking
for one to upgrade one of mine. I do have the FPF-11 floating point
processor board that alternately connects to the socket for the FIS
chip, I have a FIS chip in another processor board, but the sockets for
CIS are still vacant in both.
Once I get it / Should I ever get it, which languages could make use of
it? - Assembler, of course, and COBOL, I think?
