Ah. That makes me feel better. It was an Sun SSE that told me it was
25MB/sec, and they generally know stuff like that. It's amazing that Sun
had that bus in 1989, when IPXs & stuff were around.
Any idea what sort of machines have 64 SBUS connectors ? Are they
physically the same connector (if not, I've never seen them, though I've
seen MBUS and XBUS connectors...).

My E10000 ? Now that's a thought. Wonder would security stop you, if you
were in a big truck, and looked serious. Thing only weighes 600 kilos. Disk
cabinets are 800 kilos each though...hmm...
The PCI module just sticks into a system board slot, yeah ? Kinda like an
IO board on the Ex000s ?
