The Apple III (often styled as Apple ///) is a business-oriented personal computer produced and released byApple Computer that was intended as the successor to the Apple II series, but was largely considered a failure in the market. Development work on the Apple III started in late 1978 under the guidance of Dr. Wendell Sander. It had the internal code name of "Sara", named after Sander's daughter. The machine was first announced and released on May 19, 1980, but due to serious stability issues that required a design overhaul and a recall of existing machines, it was formally reintroduced in the second half of 1981. Development stopped and the Apple III was discontinued on April 24, 1984, and its last successor—the III Plus, was dropped from the Apple product line in September 1985.
