But you could script a data phase as lots of 512 byte MOVEs, and check
bus phase between each one - that way you can avoid most phase
mismatches assuming things disconnect on sector boundaries - that's
getting a bit silly though.  Don't recall exactly what 53c7xx does about
that, and can't be bothered to go work it out now ;)
