Checkout PUPS, they have licenses and most PDP-11 unix versions. 2.11
should run on a microPDP (11/73 or higher cpu) if it has I&D space.
The MicroPDP's I have are idle at the moment. I
want to find a decent Unix
load for them. Failing that, I will probably trade them off to one or more
of my fellow list members for other goodies.
