Just a comment. No I don't think so.
First DEC(Compaq) still holds the copyright and it's free for use, not
free of copyright. Also I haven't seen a good disassembler for PDP11
(havent really looked either).
Still POS with the programmers toolkit was a nice multiprogramming system
with graphics back then.
