It used a Z80 processor clocked at 2.5MHz, and boasted 64k of RAM. The Xerox 820-II followed featuring a Z80 processor clocked at 4.0 MHz.
This CP/M based system did not borrow much from Xerox' illustrious history of creating some of the first graphical networked computers such as the Alto and Xerox 8010 Star.
The only thing that is visibly from Xerox' workstation heritage is the design of the keyboard which shows some of the ergonomic touches of the Xerox 8010 Star.
Xerox' ad campaign for the 820 featured a group of monks in a monastary and the memorable "another miracle" ad and t-shirt (see below).
Xerox shifted its business model in the 1970s and 1980s as patent expiry removed exclusivity from their copier technology, and diversification plans largely did not succeed.
As a symbol of this transformation, the relative size of the word "Xerox" was increased in proportion to "The Document Company" on the corporate signature and the latter was dropped altogether in September 2004, along with the digital X. However, the digital X and "The Document Company" are still used by Fuji Xerox.
Xerox India is an Indian subsidiary derived from a joint venture formed between Dr Bhupendra Kumar Modi and Rank Xerox in 1983.
