Yes, check the licensing info for SIMh and a few
others. While PDP-11
OSs (RT, RSX and RSTS [it may not include all of those]) are made
available
for SIMs it is not for commercial use or operation on real hardware.
The
copyrights are still valid and some of the products are active.

One of my concerns was that the SIMH license seems a bit ambiguous as
to whether or not it covers SIMH (and there was no authoritative or
semi-authoritative opinions on the SIMH or Mentec websites). I've been
e-mailing with someone and they have clarified that, yes, Mentec's
correspondance/actions indicate that SIMH is still covered by the
"Supnik license"
even though it isn't a DEC product).
Pity that there isn't an explanation on the SIMH website, but I suppose
that Mentec doesn't want to throw money at explanations, and nobody
else wants to pontificate in an "official" manner given the current
state of the USA.
