I don't recall, since I never had one.

Evans & Sutherland Freedom series graphics accelerators were available
for Sun machines in the early 1990s.  These were essentially a
separate box with a host interface card.  The host interface for a Sun
was Sbus based.

I can't say what Sun's accelerators used to talk to the host, but I'd
assume Sbus for mid 90s models.
