Extended WSFN was an implementation created for the Atari 8-bit family of home computers by Harry Stewart, and published by the Atari Program Exchange [ [http://www.atariarchives.org/APX/showinfo.php?cat=20026 APX listing at atariarchives.org] ] in 1981 [ [http://library.stanford.edu/depts/hasrg/histsci/GamesE.htm Stanford University library "Games E" collection listing] ] .
