There is an implementors note that fast SCSI might require differential
to be reliable.  This hasn't turned out to be the case (actual experience).
Several drive vendors are saying that they support single ended fast SCSI,
but are also saying that they want the bus to be 4 meters or less, in
this case, rather than 6 m.
