I beg to differ.B  Data General was not a "fork" from Digital Equipment 
Corporation but rather started by a group of engineers who were working 
on a 16 bit replacement for the PDP-8 and left DEC and formed Data 
General when the project, code named PDP-X, was cancelled.

To quote wikipedia: "This prompted several of the engineers from the 
PDP-X program to leave DEC and form Data General 
<https://en.wikipedia.org/wiki/Data_General>. The next year they 
introduced the 16-bit Data General Nova 
<https://en.wikipedia.org/wiki/Data_General_Nova>.^[6] 
<https://en.wikipedia.org/wiki/PDP-11#cite_note-6> The Nova was a major 
success, selling tens of thousands of units and launching what would 
become one of DEC's major competitors through the 1970s and 1980s"

Data general sold nearly 100,000 16 bit computers whereas DEC sold 
nearly 600,000 PDP-11's.
