We've all but stopped shipping the SUN2 version, but we may still have it
lying around.  I'll have the librarian check.  As for version 6 vs.
version 7, we're pretty much using version 7 in both the operating system
course and my networking course.  Although there are minor differences,
version 7 is almost an exact superset of version 6 (and it's a pain to have
two different versions around).  We tell the students that when it comes
time to code, they have to use include files and not depend on constants
and/or structure definitions in the book.

The good news is that we have version 7 for the SUN3 in good shape, which
will make it easy on you if you decide to port it back to the 2s.  The only
part not quite finished is a distributed odt/download/upload system that
lets students download to an arbitrary backend machine from and arbitrary
front end machine.  That code is scheduled to be finished in 2 weeks (exams
are over here...)

There is an electronic mail list for exchange of questions and information
(xinu-info@purdue.edu).  I've forwarded a copy of this note to the list.
To have your mail address or a local alias at your site added to the list,
send a request to

	xinu-info-request@purdue.edu

If you want more information, give me a call (317-494-6009)
