No, it's a DigiData board.  Single QBUS board.  Two 40-pin connectors.

I've already been waiting a few weeks :-)

Yeah, it's the RT-11 part that I don't know.  It's a little hard to believe
that in 20+ years no-one has come up with an RT-11 program to build
UNIX distribution tapes!  :-)   (again)

The Windex and electrical tape are on me.  Did I mention that I would
happiliy provide 9-track boot service in the future?  That is.
once I can get a system running!

Not SCSI, SMD/MSCP/Pertec formatted unfortunately
