I've been
wondering, ever since I got it a few years ago, what my
PDT-11/150 would go for on eBay.
Same here... I've got a few with the EIS/FIS chip in them, maybe
that qualifies them for 'L@@K, R@RE' :-)

Just being a
PDT-11/150 qualifies them as 'L@@K, R@RE' :^) Having the
EIS/FIS chip should qualify them as 'L@@K, ULTR@ R@RE'.
Hmm, how would you qualify a CIS chip then?

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?

Cobol is the only language afaik which does use it.
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.

So, to use that fully loaded /23+ board I've got with all the options, I
need to use Cobol... I assume at least I can use the FIS from languages
other than Cobol :^) Of course I'd have thought both the CIS and FIS could
be used from Macro-11.
Maybe I'll just stick with the /73, rather than playing with the /23+ I've
slowly been getting up and running. The /73 is in a decked out BA123, the
/23+ is in a semi-decked out BA23, and I really should stick the back BA23
in storage as we need the room.

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

DIBOL required it, IIRC.

Thanks for clearing that up... I've not used cobol on the -11.
I figured it was like other optional instruction sets with
regards to layered products... like Basic, which comes in
the NHD (no hardware), EIS (for machines with EIS) and FPU
(for machines with FPU). The problem is when you run the EIS
or FPU version on a machine which doesn't have the required
hardware... it doesn't work. NHD will work everywhere since
the code it generates uses the basic pdp-11 instruction set.

DIBOL? Was there an actual COBOL for the 11?

A little more fuel for this thread: Am I right in thinking that the 11/23
and the 11/23+ use the same CPU/option chips? Can I swap chips between them?

Yes, the 11/23 and 11/23+ use the same chips. The 11/24 and PRO300
series also use the DCF11 chip. I don't know if they also use the
memory management chip...

I know... I have one (maybe two) KDF11-B boards with the CIS chip.

chip, I have a FIS chip in another processor board, but the sockets for
CIS are still vacant in both.
It was my understanding that the EIS/FIS chip is only usable with
the 11/03 (11/2, PDT) machines (and the PDT requires the dual
microm in order to make space for it). The CIS chip is a dual-wide
chip... it spans two chip spaces on the 11/23 and 11/23+ boards.

You can always do it in assembler. As for cobol or other layered
products, you probably have to use a version which has been specifically
built to use those instructions (or can detect their availability on
the fly and use them).
