Yes, those were plentiful back in the day and there's still quite a few around.

There's also new hardware being developed for SBus systems :-)

(disclaimer: work-in-progress and shameless self-promotion here!).

If there's still a distribution willing to build for Sparc v8, then I
believe the kernel

possible...

Cordially,
