Definitely VMS.  And looks like RX02 (DEVICE Type DY).
I probably couldn't read it on a PDP-11, but I guess it depends on what
the default file structure on a VMS RX02 is.  Of course a PDP-11 could
probably read the raw disk into an image and then you could  setup
a VAX with VMS in SIMH and get at them.  Oh, and it's not as much
work as it may sound like.  Looks like they are Runoff files.

Lol, true. The disks will be given back on Monday.  It's no big deal.  The
owners can decided what they want to do.  Even if I can't read it the
disks, however, pondering just what the format might be is fun. I'm
certainly learning something. Feel free to keep speculating if you are so

Here it is:

Some more info.  Anadisk tells me the disks are Single Sided, Single
Density.  It can see ID marks as it tracks a disk but that is all.  It
can't see any data.  Could be an RX02 disk as people say...
