IBM Displaywriter

IBM's Office Products Division announced the Displaywriter in June 1980 as an easy-to-use, low-cost desktop text processing system. The Displaywriter System enabled operators to produce high quality documents while keying at rough draft speed. Users could automatically indent text, justify right margins, center and underscore. They could also store a document and recall it for review or revision, and could check the spelling of approximately 50,000 commonly used words. While these features are taken for granted in the post-PC era, they were novel for a time when most documents were created, formatted and revised on manual or electric typewriters.
