Stevie was a clone of Bill Joy's vi editor created by Tim Thompson for the Atari ST in 1987. It later became the basis for Vim, released in 1991. The name stood for "ST Editor for VI Enthusiasts".
Thompson posted his original C source code as free software to the comp.sys.atari.st newsgroup on June 28, 1987. Tony Andrews added features and ported it to Unix, OS/2 and Amiga, posting his version to the comp.sources.unix newsgroup as free source on June 6, 1988. In 1991, Bram Moolenaar released Vim, which he based on source for the Amiga port.
