UnixPC memory upgrade

Re: the "$355 Manual Set"

The ``AT&T UNIXPC REFERENCE MANUAL'' is a large slip-cased tome in which are
contained the schematics for most (not the International version) variants
of the UNIXPC, the "theory of operation" of the various custom and other
chips, relatively complete description of system diagnostics, schematics for
all AT&T expansion boards for the system, and some other tidbits.

Although pricey, $355 is in the ballpark range of similar documents for other
computer systems, and I suspect the price covers the actual production costs
(i.e. no profit) considering the limited press run of this type of material.
