I never looked it up specifically, but it's pretty obvious from looking at
the SCSI protocol specs that the addressing and bus mastering and such works
by pulling down zeros and letting ones float. Hence the "SCSI Priority"
being the LUN and having "0" always be the host. It's a pretty common way
of working a shared bus, from ISDN to those one-wire protocol capsules.
