I've not used them, but I do have a copy of the KA630 manual which
does, indeed, claim that it's possible to do it. It would be very,
um, challenging.

Probably not. Such a system would not be a symmetric multiprocessor; the
additional KA630s would each need their own memory (which means you'd
need a custom backplane to build the system in; basically, each KA630
would have to have its own set of CD slots for the PMI). Fundamentally,
the multiprocessor support in the KA630 consists of a way to use an
external bus arbiter and a doorbell register.
