The Apple III computer was first introduced in 1980 and was intended to be aimed at busines users. It was the first Apple machine to incorporate a built-in 5.25 inch floppy disk drive and high-resolution graphics built into the motherboard. Unfortunately the machines suffered from numerous problems and sold poorly. An improved and lower-priced Apple III was launched in 1981, followed by a III+ in 1983, but the computers continued to be unpopular, and production ceased in 1985.
