Be forewarned that a KZQSA isn't a "real" SCSI controller. It's doesn't use
MSCP, and doesn't emulate any better-supported controller. It only is
intended to support a few specific tape drives and CD-ROM drives. It's
supported in some versions of VMS; I'm not sure about Ultrix.

I don't think it can be used as a boot device, though I'm less certain
about that.
