I have had several 53Ds and T22s so I can verify those
numbers. I had some
8010s with a different number but I am not sure it was K91. It seems to me
that it was different, but this was 7 years ago.
This one has T22F on a serial number plate; there are no other obvious
markings.

Yes, I think most D-machines do, as did the somewhat
related PERQ
machines (which I know rather more about). This is a really fun feature
IMHO (I _like_ writing microcode, OK :-)), and is one reason why I
collect such machines.
Yes; more interesting than the processors I see people building now.
The only device that I know much about *and* that is user-programmable is
the TAAC-1 graphics board for the Sun-3. I've never actually *seen* one,
but I once worked on a compiler for it.
I'm looking for this as well. Actually I'm
looking for any technical info
on the Daybreak (== anything that _I_ can't work out in 10 minutes of
looking at the machine :-)).
I suspect you could work out more in 10 minutes than I could in 10 days.
In 10 minutes I could *probably* find the power switch -- if it's not
behind a door.
There appears to be some information on Al Kossow's site
(http://www.spies.com/aek/) in PDF form; I haven't looked at any of it
yet.
I can teach you PERQ microcode, but although there are
similarities, it's
not going to help that much.
I think I have read something -- a series of Usenet posts? -- that you
wrote about the PERQ. They don't seem to be at all common here; on the
other hand, I didn't expect to come across the Xerox machines either.

I suppose you could also trace what the fuse is
connected to...
One side is straight on the line; the other is connected to a small
transformer on the fuse board. The secondaries lead to the front panel....
