Gosling Emacs

Gosling Emacs (often shortened to "Gosmacs" or "gmacs") is a discontinued Emacs implementation written in 1981 by James Gosling in C.

Gosling initially allowed Gosling Emacs to be redistributed with no formal restrictions, as required by the "Emacs commune" since the 1970s, only asking for a letter acknowledging his authorship. Later, wishing to move on, he sold his version of Emacs to UniPress. The dispute between Richard Stallman and UniPress inspired the creation of the first formal license for Emacs, which later became the GPL, as Congress had introduced copyright for software in 1980.
