Zenith 100 Home Computer

Zenith Data Systems was founded in 1979 by Zenith Electronics Corporation, after acquiring Heathkit. The system runs both CPM and MS DOS, but was not yet the "PC compatible" machine.

The Zenith 100 Home Computer was developed in 1981 and the later, improved, the 100 uses a Z-80 processor chip and a 8088 chip. Introduced in 1979, it was bought out in late 1989 as Zenith exited the micro-computer market. This example was donated by Bob DiPippo of West Warwick, Rhode Island. Software includes the word processors Spellbinder from Lexisoft, Inc., and WordStar; the spreadsheet program Supercalc; Microsoft BASIC; and games, including Adventure and Zork.
