I think you mean KZQSA. A strange device, i think it is intended as a tape
controller von 4000 series VAXen. Only 4000 firmware knows about it, my MV
3400 doesn't show it up. It seems to be some dumb controller with 128 KB of
shared memory... maybe some kind of VAXstation-SCSI-subsystem as QBus card.

If someone has technical information about it... :)
