It does... I've done it (back when I was doing some work on having
KFQSA in a qbus pdp-11 and running RT-11 on the disks it was
attached to).

They don't allocate addresses as you put disks on... you have to
configure the board using the SET HOST command on a uVaxIII
(which is what I did). I think you have to set the board to a
specific address to program it first, and once programmed you set
it back to the normal use address (there is a 4-switch switchpak
on the board)
