My first exposure to FC _drives_ (as opposed to enclosures with genuine
SCSI drives and an external fiber link) was in 1997/1998... Seacrate,
IIRC. I remember a funky connector that was pretty small... smaller than
40-pins even, but I'm not as sure of that detail.

FC drives are SCSI command protocol, serialized data rather than parallel
(like a 50/68/80 pin drive), and some FC-oid physical layer/signals/voltages.

I am not aware of a simple adapter to use an FC drive with an older machine.
I have seen PCI and Sbus FC adapters. It might be possibly to cobble something
up with one of those, but not with, say, an Adaptec 1540.
