  The very first PCI Suns do 64-bit 66MHz PCI?

  There are other issues here...Sbus can initiate a new transfer
immediately following a completed one, whereas PCI takes several for
setup.  There are a few others but I don't recall the details offhand.
Now mind you, I like PCI a lot...but SBus is a better design, in my
opinion, aside from the expensive connectors and the utterly LUDICROUS
restrictions on the physical size of the board.
