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. On Dec 6, 2017 9:47 AM, "Aaron Jackson via cctech" wrote: I'm looking after a VAX 4000 for a friend, which has a SCSI Q-bus card (M5

The metal face on the Q-Bus cards was there as part of the solution to meet FCC (or equivalent) regulations to reduce electrical interference to radio receivers and other devices. If you can physically fit it into a older Qbus backplane and sort out the cabling it should work provided you have
