OMNIWRITER
OMNIWRITER is a word processor for the Commodore 64 home computer published by Jeff Minter's HESware. Called "Dean of Commodore 64 word-processing programs" in Stewart Brand's Whole Earth Software Catalog, OMNIWRITER sold at a list price of USD$79. It was specifically recommended for home business use.
The package included a reference card that fit around the Commodore's function keys, customizable colors, and scrolling 80-column width display. The maximum file size was 23 pages, but multiple files could be chained for printing. OMNIWRITER could import up to 240 columns of data from Microsoft Multiplan.
