I define a real-time system as any simulation requiring that a finite
amount of work be accomplished in some specified, predetermined interval
of time.

Classification by taxonomy is useful, but only for discussion.  Imbedded
or non-imbedded; those are the only ones that I know of.  I think about
real-time systems as consisting of some combination of synchronous and
asynchronous processes.  Each may rely on interrupts, polling, or message
passing to operate.

While I'm on the subject, does anyone know of any references to real-time
multicomputer systems using transputers?  I'm working on a book entitled
"Real-time Multicomputer Software Systems" and I'm curious to know if any
one may have a requirement for such a beastie.
