From the publisher, Prentice-Hall. You call them up, they'll tell you
the exact address, and you send them a few bucks ($50? $100?) and they'll
send you a magtape. You will have to show them a UNIX source license,
unfortunately, since the tape is just chock full of nifty PDP-11/05
cross-tools (that run on a VAX) that contain licensed UNIX source code
(mostly the compiler, libraries, and loader).
If you can find a neighbor who already has the tape, it is legal for
you to get just the XINU sources (the stuff in the book) from them.
(When I was at Fortune, one of the guys wanted to use it in a class,
and we checked with Comer about it. 'S cool.) The XINU source itself
doesn't need a UNIX license, natch. (Hmmm... that "o.k." was for personal,
research, or educational use. For commercial use, better check again
with P-H or Comer about copyright.)

The source is available from the publisher for $50 on 9 track tape.
The hitch is that you have to have a Unix source license to purchase it.
I was interested in getting it up and running on a homebrew NSC 32032
based system, and went through all kind of gyrations to wrangle a copy
from them without the source license. All attempts were equally
unsuccessful.
I can probably dig up the specific name and address of the individual
I ended up dealing with at the publisher if you're interested. Spending
upwards of $50,000 for personal computer operating system software
cooled me off to the whole idea.michael@nvuxd.UUCP (M.CAIN) (01/24/85)
One of the guys who works for me brought XINU up on a Heurikon 68000 board. He had some lengthy phone conversations with the author of the book, who says that the code proper is "public domain and not copyrighted". Rather than go to the hassle of trying to order the tape, he spent several evenings typing the source in manually. While tedious, it worked, and he is currently running several interesting digital signal processing applications under XINU. Michael Cain Bell Communications Research, Inc.
