History

Founded in 1982 by Robert Harp, who previously helped found Vector Graphic.[4]

The original Corona PC was released in 1983.[5]

By 1984, Corona employed 280 people.[4]

IBM Lawsuit

Corona claimed "Our systems run all software that conforms to IBM PC programming standards. And the most popular software does."[6] In early 1984, IBM sued Corona and Eagle Computer for copyright violation of the IBM PC BIOS. Corona settled with IBM by agreeing to cease infringement.[7]

Corona Portable PC Model PPC-400, arguably the most notable Corona computer, was introduced in 1984. The PPC-400 was remarkable for its elegant and clear screen fonts. The desktop version was the PC-400.[8]

Cordata

After Daewoo acquired a 70% share in the company, Corona Data Systems was renamed Cordata in 1986 in order to reflect diversification and to try to distance itself from identification as just a "PC clone" manufacturer.[1] Harp resigned in 1987, accusing Daewoo of transforming the company into a paper-only entity for the purpose of loss write-off. According to Harp, Cordata had posted $20M losses in the previous year despite the $40M investment made by Daewoo since 1985.[9]

Competitors

gollark: Tesla bad because repairability issues and accursedly proprietary software.
gollark: Sure, but I doubt it'll work well on the available RAM.
gollark: It had trouble generating chunks when I tested it.
gollark: I have a server which isn't doing much, but it only has 4GB of RAM.
gollark: Well, I'm on again now.
