Several people have reported success running on SuperSPARCs without an
external cache attached (includes two clones) which for a long time was
the one remaining Viking model on which NetBSD wouldn't run at all.

I can't tell you about Hypersparcs (Ross 625). There's support for this
model in -current, but it's not tested. If anyone has access to a Hypersparc
machine, please give it a try.
