"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 III+ ($2995) in Late 1983. The Apple III+ was discontinued in 1985."
