Sort of.  There are also 82x0, 83x0, 85x0, and 8800.  Collectively
these tend to get referred to as 8xxx.  The 8600 series is special,
being after all an SBI Vax.  The full listing as I know it:

	8200		(~= 780 speed; why would you want one?)
	8250		(~= 785 speed.  " )
	8300		(dual cpu 8200)
	8350		(dual cpu 8250)
	8500		? up to 4 cpus?
	8530		? ? does it exist?
	8550		? identical to 8500 but faster
	8700		? up to 8 cpus, I think
	8800		? up to 12 cpus, I think

There may be an 8750, but I do not recall it.  Everything after
8350 above is suspect.  The 8800, at least, has as its main bus
something called the `MI' (Memory Interconnect) on which sit the
CPUs, the memory, and up to 2 (at last count) DB88s, each providing
two VAXBI busses.
