To answer the questions, in order:
Yup. Another Yessir. Any decent Ultra controller will do. It is the 8 bit
variant, and so only uses those lines. It is kind of nice, because you get
the benefit of 20MB/sec data rate (same as wide) without paying the price
for 68 pin cabling. It also means you can use the same cabling for your
non-ultra devices, such as other HD's, tape, CD-ROM, without nasty cable
tricks. Final reason to love it: It's cheap!
Typical Ultra narrow drives are now coming out for same costs as older
SCSI-2 drives (or less). No fancy extra hardware is needed, as all they are
doing is driving the bus at a higher clock for those ultra devices.
