I find this conversation very interesting.? I was always led to believe

got all the PDP-11 OSes except IAS? (supposedly because DEC still had

commitments) that it eventually faded into obscurity and was lost.
Obviously, not the
case.? Has anyone ever approached HP about the possibility of just
releasing it all to
the world as either Licensed Open Source or just public domain?? Not my
favorite OS
by any means, but better than the nothing we have for the PDP-11 today.

Probably more that just ?slightly? hacked but certainly not a completely new

Wow, I did not
know that. It certainly confirms that IAS is just a slightly hacked RSX-11/D...

this is actually RSX-11D? http://bitsavers.org/bits/DEC/pdp11/magtapes/ias/
Yes.
The two V3.4A tapes will allow you to build either RSX-11D or IAS.
