I saw the DSM, but I've never heard of anyone actually running a MUMPS system,
least of all on a QBus machine. Course that's not saying much since I forgot
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.
