Apple III computer and monitor, 1981. The Apple III computer was first introduced in 1980 and was intended to be aimed at business 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.
