What PDP-11 OS screen is this?
Late version of RSTS?

I can say with certainty it is not RSTS. Might be DSM?

Definitely not RSTS. Not any OS I've ever seen, actually (not RT,
RSX, IAS, BSD, DOS, RSTS, or Ultrix...).
The message at the bottom mentions "DSM blocks". So I wonder if it's
DSM-11.
Is someone selling that? I know at least one person who might be
interested (slightly, anyway)...

completely about IAS, and Ultrix and never have seen these either, but
they're there.
With the XDT at the top of the screen I thought it might be M related,
but M was never friendly (?) like that. :-)
Maybe Mplus?
And I don't think DEC made a RK06/RK07 QBus interface (DM2, DM3, DM4 on the
screen).
Though Dilog, and others possibly, made QBus controllers that emulated
those drives.
Anyway it was supposedly for a QBus PDP11 memory board but seemed funny to me.

It is.
I saw the DSM, but I've never heard of anyone
actually running a MUMPS system,
I do, as do two of my customers. One on a
MicroPDP-11/83, and the
other on a sortof homebrew 11/73.

Ultrix-11 rocks!

interface (DM2, DM3, DM4 on the

Emulex and Dilog both did. There were liked a lot by systems
integrators
that needed modern drives, full compatibility and a lower price than the
DEC stuff. This is probably DSM-11 on some OEM 11/73-ish system with
one of those boards.

Nope, DSM-11 aka Digital Standard Mumps. The PDP 11/84 at Bletchley Park is
running DSM-11, and after fitting a new DEUNA to it the other month I had
pleasure in trying to figure my way round the OS to get troubleshooting
info......got it in the end but hells, talk about difficult!
Cheers
