22-bit, for the MicroVAX II CPU you have

Likely an 18-bit backplane for the -11/23 CPU.

I'm guessing this is a 16-bit backplane for the -11/03

Have you Googled these? Google Groups aka DejaNews will be the most
help. The first three *might* be some sort of SCSI, if so I'm
guessing that second one talks to tape drives. Can you provide
pictures of the 3rd party boards? Those are more useful.

Useless, it's for a Versatec plotter.
Did you get any drives with any of this stuff?
