EasyWriter is a word processor released when the IBM PC was announced in 1981. It was written by Capn Software, which also produced a version of Forth — see Byte Magazine, January, 1982, p. 62.
EasyWriter was not received well and was soon replaced by better programs, such as WordStar, which was ported from CP/M. EasyWriter was probably hastily selected by IBM because of its rush to introduce the IBM PC.
