I knew that, but if study is the main goal... some of the lessons have
been already incorporated. It would be cool for the geek factor I grant

Anyhow, there is always the emulator route I guess... if there is enouhg
info on the underlying HW I am sure an emulator of sorts could be written
and run some original multics on it. However is it hte multics code

The only thing I sort of know about multics is the whole concept of
protection rings (hence their logo). I seem to remember that was its
biggest stregnth and weakness, since it induced a significan overhead on
such old iron. The instruction set I think reflected the need for
protection based not on memory mapping but in actual
instruction/program/user privilege level. I guess now my curiosity has
been itched... I am looking over the multicians.org website which seems to
be the main web info repository on the subject.

BTW, I sent an e-mail to the original article author, as he pretty much
plagiarized info from the multicians.org website. I have no problem with
authors copying public sources of information as long as they credit the
original authors. I have seen that over and over and over with teh so
called "reviews" in osnews/opinion and whatnot websites.
