Don't know about the others, though I have my guesses about RSX -- but
in the case of RSTS at least, software development was "native"
not later than 1975 or so (RSTS/E V5B).

The time frame I was really thinking about was '65 -> early 70's


  And RT11 development probably
was hosted on RSTS at some point.  (So was OS-8 support, on an 11/60,
since it could run PDP-8 code very fast thanks to the WCS option.)

I'm sure Megan knows all the gory details of that.

This is also the first I had heard that Richie's PDP8 microcode was
actually used for product development.
