Jon,

You are mistaken.  The CPU board and upgrade to a model 32 are
really based on Zilog components, and not a 3B2 in a Zilog
cabinet.  The CPU board does contain a Western Electric chip, but
thats about it.

The Manuals are the AT&T System V set for the 3B2, only because
that is a very good set of manuals for System V, and very usefull
for the System V version of the operating system that is now on
your Model 32.  Besides these manuals, you should have received a
few more Zilog manuals, like the S8000/32 System Administrators
manual to help supplement the System V manuals you have.

Before you slam Zilog and your site upgrade, you may wish to give
us a call.  We are under contract to help support you.  The
Centel hotline number is (703) 758-7000.
