AFAIK the KZQSA was intended as a tape only adapter
for the later VAX
4000 QBus machines. It needs special drivers, it does no MSCP emulation
like e.g. a Dilog SQ706. So you would need new drivers for RT-11.
I *believe* that the only DEC Q-Bus adapter that RT-11 supports is the RQZX1
(as mentioned in the V5.7 SPD). Pretty much any 3rd party disk controller
that does MSCP emulation (DU) should work. For tape you need TMSCP
emulation (and V5.4 or higher).
