Actually, you can run Solaris 8 (maybe even 9) on a SPARCserver 670MP,
provided that your MBUS CPU modules are still supported (it's the same type
of modules used in the SS10/SS20/SS1000/SS2000).  However, you won't get
VME support (that's ok, the 600-series also has SBus, and I doubt you'll
run across any VME cards you really need anyways).  Basically, you just
have to hack the kernel to disable a section that essentially says "If this
is a 600MP series machine, don't boot".  In reality, the 600MP series is
just a sun4m /w VME slots.  So Solaris 8 will work just fine, albeit
without VME support.

(these instructions are for Solaris 2.6, but I've used them (albiet with
some poking around, as the addresses in the 8 kernel are different) to
successfully hack a Solaris 8 kernel)

However, as this involves a kernel hack, the actual installation isn't as
straightforward anymore.  You basically have to either swap out the kernel
on the install CD (i.e. modify the ISO), or do a network install (where it
is easy to change anything).
