Hm, is it a two-processor machine "by default", or _can_ it be one?
I don't know the 8xxx series, and the DEC specs I have don't say
anything about this.

Hm, was the 8800 the first VAX to have multiple processors without any
tricking? And what were the 8974 and 8978 configurations _exactly (how
many processors, HSCs, SAs)?

And if not to a HSC, what then? To an UDA/KDA/xxx?

Yes, I saw these beasts (or very similar ones) in IBM mainframe
configurations, under the number "3480" or so :)

The 6200 had XMI? I did not know that...
