Interesting. That sounds like a product-specific item rather than part of the
standard architecture.

I don't have time to dig up the details. But TOPS-10/20 definitely
supported the CI. It turned out not to be used much since IIRC despite
the high wire speed, thruput was better on the NI. But the rationale
was something like if you had CI connectivity for storage, and an NI

Folks,
I googled and found some ROM dumps. I found out that SIMH repo already have
original firmware (KA620, KA630, and KA655). It do not have original KA610

Also, I found KA640 and KA650 fw files and downloaded both. I can't find

Folks,
I discovered CI750 tech docs when I searched for some CPU processors for VAX
emulation. I downloaded and reviewed it. CI emulation can be implemented
for emulator to link to other VAX/Alpha emulators as VMScluster. Does anyone
find CI780 emulation for VAX-11/780 and VAX 86x0 yet? Also
