engineer and a motivational factor for the Apple workforce. Return to Apple product development Starting in the mid-1980s, as the Macintosh experienced slow but steady growth, Apple's corporate leadership, including Steve Jobs, increasingly disrespected its flagship cash cow Apple II seriesand Wozniak along with it. The Apple II divisionother than Wozniakwas not invited to the Macintosh introduction event, and Wozniak was seen kicking the dirt in the parking lot. Although Apple II products provided about 85% of Apple's sales in early 1985, the company's January 1985 annual meeting did not mention the Apple II division or its employees, a typical situation that frustrated Wozniak. Final departure from Apple workforce Even with the success he had helped to create at Apple, Wozniak believed that the company was hindering him from being who he wanted to be, and that it was "the bane of his existence". He enjoyed engineering, not management, and said that he missed "the fun of the early days". As other talented engineers joined the growing company, he no longer believed he was needed there, and by early 1985, Wozniak left Apple again, stating that the company had "been going in the wrong direction for the last five years". He then sold most of his stock. The Apple II platform financially carried the company well into the Macintosh era of the late 1980s; it was made semi-portable with the Apple IIc of 1984, and was extended, with some input from Wozniak, by the 16-bit Apple IIGS of 1986, and was discontinued altogether when the Apple IIe was discontinued on November 15, 1993 (although the Apple IIe card, which allowed compatible Macintosh computers to run Apple II software and use certain Apple II peripherals, was produced until May 1995). Post-Apple After his career at Apple, Wozniak founded CL 9 in 1985, which developed and brought the first programmable universal remote control to market in 1987, called the "CORE". Beyond engineering, Wozniak's second lifelong goal had always been to teach elementary school because of the important role teachers play in students' lives. Eventually, he did teach computer classes to children from the fifth through ninth grades, and teachers as well. Unuson continued to support this, funding additional teachers and equipment. In 2001, Wozniak founded Wheels of Zeus (WOZ) to create wireless GPS technology to "help everyday people find everyday things much more easily". In 2002, he joined the board of directors
