Corona Data Systems, later renamed Cordata, was an American personal computer company. It was one of the earliest IBM PC compatible computer system companies. Manufacturing was primarily done by Daewoo of Korea, which became a major investor in the company and ultimately the owner.
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. When it is stored in a closet your would almost mistake is for a sewing machine :)
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. I guess today in 2020 they would also rename it, but for different reasons.
One thing you notice when you start the system is the monitor is very very sharp and text just pops out of it. It has 512K Memory installed and MS-DOS version 3.10. Althou they ended up in court with Microsoft because Corona claimed "Our systems run all software that conforms to IBM PC programming standards. And the most popular software does.". So 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
This system has a very simple IO or connections, One Parallel port, One Serial port and then just they keyboard plug at the front of the computer. It also has one HD and one 5 1⁄4-inch floppy disk drive to the left.
Super quality build and quite stylish in a retro kind a way. I would have on the kitchen table at all times if it was my decision alone to make : )
