The earliest version of Vim was developed on the Amiga by Bram Moolenaar in 1988. ... He based his new editor on Stevie, which he has said was the best Amiga-compatible vi clone at the time.

Archived fromthe original on January 7, 2016.Is VIM derivate of other VI clone or you started from scratch? I started with Stevie. This was a Vi clone for the Atari ST computer, ported to the Amiga. It had quite a lot of problems and could not do everything that Vi could, but since the source code was available I could fix that myself.
