[cctalk] VAX 4000-200 in BA215 chassis. Can I install a KFQSA card and connect the cabinet disks to it?

I have a couple of VAX 4000-200 boxen running OpenVMS. I want to try out NetBSD on them but NetBSD does not support the SHAC DSSI controller on the KA660 CPU card. However NetBSD *DOES* support the KFQSA DSSI controller which I have a few of in my VAX 3800s. Can I install the KFQSA card in my 4000-200, disconnect the internal disks from the SHAC and connect the disks to the KFQSA thereby allowing NetBSD to run? Has anyone done anything like that? Happy 2024 everyone! Thomas Dzubin Calgary, Vancouver, or Saskatoon CANADA
