IBM EasyWriter

EasyWriter is a word processing software released when the IBM PC was announced in 1981. It was written by John Draper's Cap'n Software, which also produced a version of Forth.

Draper wrote EasyWriter, the first word processor for the Apple II series, in 1979. According to the Wall Street Journal, he hand-wrote the code while serving nights in the Alameda County Jail, then entered the code later into a computer. However, another account had him writing the code as he served his four-month sentence at the Federal Correctional Institution, Lompoc, California.
