A pdp11/53 can run all the OSes Brian mentioned, to which I'd add RT-11,
(specifically) 2.11BSD (no need to run 2.9) and Ultrix 3.x, and that's a
fairly simple and straightforward tower machine, and certainly a lot
smaller and more power-friendly than an 11/70.

<https://skn.noip.me/pdp11/pdp11-45.html>has a nice collection of
operating systems running on a 256K system. 2.9 BSD boots and runs from an
simulated RL02. (2.11 BSD needs an 11/70 or better.) This should at least
show what is possible.

What is the simplest PDP-11 CPU/peripheral design
that is capable of
running RSX-11, RSTS/E or BSD?
Define "simple" please. :-)
Also, what is the minimum disk space needed to
install those operating
Ok, that's what I needed to know (more ballpark than anything else is
fine)
Thanks!!

systems? I have a plan. Probably not a good one
but I'll likely learn
a
lot in the the process so it won't be a waste
of time.
RSX-11M-PLUS can run from two RL02, if you just accept the pregen
system. But that's the smallest. If you want to build stuff, something
like an RK07 is required, and that is 28 Megs. But I think it's
recommended that you have two. But that probably is for more reasons
than just running the actual system (it is hard to do an update if you
are running on an RK07, and the update media is an RK07).
RSX-11M definitely gets away with less. RSTS/E would be similar, I
think, while BSD probably wants a little more.
