The Corona microcomputer model # PPC-400 was introduced in 1983. Corona Data Systems Inc. built some of the earliest IBM PC compatible computers. PPC stood for portable pc and came with a built in carrying handle on the back. A carrying case with shoulder strap was also available. The base model, weighing 28 lbs., used an 8088 CPU, had 256mb of RAM, one 5 ¼ floppy disk drive, four expansion slots, integral 9-inch monochrome display screen, standard keyboard, RS-232C serial port and a parallel port. The display screen had 16 x16 pixel characters and super-resolution 640x325 pixel graphics – nearly twice the resolution of IBM PC models at that time. The retail price in 1983 was $2,395.
Corona Data Systems Inc. built and sold IBM compatible PCs under their name as well as under the names Olivetti, Sperry Univac, and Phillips.

Traveled from fl to Moffett field near SF lugging one of these and a Hayes modem & assorted accessories thru the air ports. I looked like a fiddler crab on one side from the schlep. Was doing a job for the Navy and was transferring messages via a BBS (pre-internet email) back to the office overnight. Nave was amazed that we had status reports before they did. All because of the Corona. We had upgraded it with a full load of RAM and the 8087 math coprocessor and we ran AutoCAD 2.x - a feat on any type of computer in the early 80's.
