Son of a gun! It works! I had given up on using my DSSI disks at all so
I stuck SCSI cards in all of my QBUS machines.
Much Thanks to Chuck McManis for this seemingly simple pointer.

I've got six 4000-200s (but only one lousy KFQSA) in my basement
Yay!  Another machine to run NETBSD on!
(anybody got any spare KFQSAs they want to sell me?  (or trade: I've got a
spare PDP 11/34 data paths (M7265) board that I don't want))
Hmmm...maybe I should take this conversation to the classiccmp.org mailing
lists...
