An M5976 KZQSA is not MSCP compatible so it wouldn't do any good with a PDP-11 system. It's really only useful for RRD4x SCSI CD-ROM drives with VMS on a VAX 4000.

If the card did not have the large metal face, would it work in a Q-bus PDP-11? We are not going to potentially ruin a card by trying this, but I am interested to know if this is the case. Thanks, Aaron.
