Is there an archive of The Western Electric Engineer journal online
anywhere? In the July 1977, Volume 21, Number 3 issue there is a 7
page article "MAC-8: A Microprocessor for Telecommunication
Applications", by Herbert H. Winfield".  which provides a good
architectural overview of the MAC-8 for those that are interested.

Several years ago I found that the University of Minnesota Libraries
had that issue in their collection and they were able to provide a
photocopy on request for a minimal charge to cover processing and
copyright expenses. From a quick glance at their website now it's not
obvious if they still provide that service, and still have that
journal in their collection.
