Won't you have the same problems if you teach one of the SCSI chips to
use (say) ID 6?  Won't they both think they are "the" host on the bus?
How would these two situations differ that makes one work and the other
not?

Or am I just exposing my ignorance of SCSI?  Is there a canonical
reference somewhere I can go read to Learn All About It?
