What I recall for a DN20 was that, in terms of communication, MCB only
had two speeds.

That's the KMC-11, and it does indeed have a processor on it. It can
do all sorts of protocol processing, very flexibly.
It's a weird connection to have, but I was romantically involved with
the daughter of the designer of that board for a while, and have been
friends with him just about forever.
He gave most of his personal DEC hardware to me many years ago, and
it's at LSSM now. He's based in Maryland.
He's still very much around and still loves DEC stuff; I should talk
him into joining us here.
