All together, take a deep breath and repeat "KZQSA is a really dumb
controller." It does not know MSCP or TMSCP. It is useful only on
certain varieties of VAX that have code in the boot ROM to handle it.
Frequently confused by analogy with KFQSA, which is a much smarter
controller that does DSSI on Qbus.
