Nice. I have a couple of older Alphas (one is *much* larger, with a
Futurebus+), so I know a little about the line, but not the later
models. I had no idea HP packaged them up with their hot-swap drives.
I've only ever seen DEC-badged Alphas in person.

I was part of the team that created the Futurebus+ specification.
My name is in the front with the other authors.

Indeed it is. After digging up P896.1 I went and checked Digital Tech
Journal V5 N1,
which includes an article about the DECnis and that does indeed use FB+.
I've found one Cobra (DEC 4000) document that indicates it uses FB+ too.
(Just in case someone really needs to know when browsing the list
archives eons from now ...)
The Cobra System Overview mentions that, as FB+ was an open bus,
3rd-party options might
be made available, for example HPPI and a VMEbus interface. I don't know
whether anything
like that ever happened. I don't think the DEC 4000 lived long enough
for much of a market
to build up and I don't know of any other DEC systems (apart from
DECnis) which used FB+.
