Mostly I read the source, starting in university where we were running RSTS-11.  I started working on it at DEC in the V7.0 era, for DECnet V2.0.

I don't remember if any of the material in bits/pdp11/rsts on Bitsavers is RSTS-11.  There is the material from PDP-10 tapes that was discussed here in the past year, which I identified as very early RSTS sources.  I don't know yet if they are complete enough to run, that would be an interesting experiment.

FWIW, there's a RSTS/E V10.1 source master copy (including DECnet/E and build control files) among the Bitsavers materials.
