[Simh] Lost PDP-11 OSes?

[Gregg Levine]

Hello!
Take a look at the list of PDP-11 OS examples on the Wikipedia site.
Of those I think I recognize most of them. This includes the ones
discussed here. For myself I'd like to track down the last known
working release of the R named operating systems for the PDP-11. Up to
the user to pick one.
