Re: 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. --ab
