Subject: Re: Chip Upgrades for 11/23 (was Re: 11/03 system on eBay sold)
Sorry to correct you, but EIS/FIS is an option to the F-11 uprocessor, hence
for 11/23, 11/23+ and 11/24 computers. I'm not aware of any CS-firmware options
for 11/03 or 11/02.
Yes, there sure was a CIS chip for the 11/23[+].
And I am still looking
I know... I have one (maybe two) KDF11-B boards with the CIS chip.
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.
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.
Dibol does that.

Once I get it / Should I ever get it, which
languages could make use of
it? - Assembler, of course, and COBOL, I think?
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).
