Subject: Big Board/Xerox history

Yes, the Xerox systems and Kaypros were both based upon the Big Board.
The 820-I is, for all intents and purposes to me, a Big Board with some
frills.  The -II and 16/8 became progressively different from the mother
system (evolution, I suppose is the word).  The same is true of the Kaypro
systems; they started out as Big Boards with some changes, and then
progressed, although on divergent paths from the Xerox line.  This
explains the communications ports similarities, and the basic screen
code similarities.
