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).  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.)

Early on certainly TOPS-10s were used; an old DEC document (for kernel
ODT for RSTS V4) has a passing reference to a DEC-10 based PDP11
emulator called "MIMIC".
