The Apple III was announced in June 1980. It contained a Synertek 8-bit 6502A processor which could run at speeds up to 2 MHz. It contained 128K of RAM and a 4K ROM. It could run most Apple II programs through emulation, and came with a sophisticated new operating system. It was the first Apple to include a built-in 5.25" disk drive, and hi-res graphics built-in to the motherboard. It was designed to be Apple's business offering, but sold very poorly. It sold initially for between $4,340 and $7,800, depending on the configuration. The original Apple III had many problems, and was replaced by a revised model in mid 1981, which featured 256K RAM, updated system software, and a lower price ($3495). A 5 MB external hard disk was also made available. The Apple III sold very poorly and was replaced by the Apple IIIplus ($2995) in Late 1983. The Apple IIIplus was discontinued in 1985.

Here's another tidbit you might add: Rupert Lissner wrote a program for the Apple III, called 3-EZ Pieces (I might be spelling it wrong). It combined spreadsheet, database, and word processing -- and was probably the first "works" program. Of course, like the Apple III, it didn't sell well. However, when the Apple IIe was introduced, so was a new version of Lissner's (come to think of it, I might be spelling his name wrong, too) software, as AppleWorks. It became the biggest-selling software package of all time, and Rupert became rich. He bought a red Ferrari and a vanity licence plate reading "MIO POMO" (my apple). - John Huber, Apple employee 1982-1994
