Corona PC and Corona Portable PC

Corona Data Systems was another contender in the early IBM PC compatibles market. The company was moderately successful at first, selling 5,000 desktop and portable PCs from December 1983 to January 1984. In 1985, South Korea’s Daewoo Group bought a controlling interest, later renaming the company Cordata in 1986.

The Corona PC and Portable PC were the company’s first IBM compatibles. They had fairly standard PC configurations and were true IBM compatibles. That fact drew the attention of IBM, which sued Corona (along with Eagle Computer) for copyright infringement on the BIOS. Corona ultimately settled by agreeing to use BIOS code that did not violate IBM’s copyright.
