Born on Data General: 1979; ported to DOS: 1982; still on life support
In 1979, Brigham Young University contracted a group of programmers to build a word processor for its Data General minicomputer. The programmers formed a company, Satellite Software International, and started selling SSI*WP for a mere $5,500 a pop.
WordPerfect 2.20, the first DOS version, appeared in 1982. By 1986, WordPerfect 4.2 was by far the best-selling word processor. With LAN support (1988), pull-down menus (1989), WYSIWYG mode, reveal codes, styles, diverse printer support, and macro language, WordPerfect ruled the roost.
Then Windows hit, WordPerfect didn’t jump soon enough, and Word for Windows ate its lunch.
WordPerfect for DOS Updated continues under the caring eye of über-guru Ed Mendelson.
