SMS model OMTI 3100 bridge

There's one of the same devices, Microscience drive and all, sitting at one
of the local surplus vendors. Unfortunately they don't know anything about
it either. It may respond to only one SCSI address, however, though you can
easily modify that if it's the case.

The one I'm writing about has no external shell, so it's complete except for
the cover, but it's clearly a 31xx series OMTI controller with the Z8 and
2764. I imagine it costs about what the 2764's in the parts drawers cost,
though it's probably a 110 MB drive or so.
