It depends on what system you are writing/studying for.  Their book is clearly
written and includes numerous source code examples.  It is clearly for a
Masscomp machine (they make no pretense about it) but the discipline and
approach are valid for any System Vr2 or later that I'm aware of.  The book
is well worth the money if used in concert with something else (unless you
have a Masscomp).  The (terrible!) AT&T documentation is useful to understand
how the kernel generation process works.  Chris Morgan's book "Inside Xenix"
is as close to publishing a proprietary tty driver as you can get.  I got the
Egan & Teixeira book last and it was a worthwhile addition to the pile.  I
have been able to struggle through without it but it was still helpful.  I'm
not sure I'd choose it if I could only have one book (unless I had Masscomp).

The opinions are my own, Tolerant is nice enough to let me use their equipment.
