I would definitely check source listings. Also, check BSD/Ultrix
_and_ VMS. I guarantee they don't do everything the same way (case in
point RB730 controller initialization) but both will be insightful.
My own Unibus (and Qbus and VAXBI) experience is with comm drivers not
storage drivers so I don't have any insights on block transfers and
purges, unfortunately.
I'm excited for the results of this.
