Apple II
Apple II signed as Apple ][ was one of the first mass-produced 8-bit home computers to be successful around the world. Like Apple I, Model II was also designed by Steve Wozniak. It is worth noting that Steve Jobs also participated in the process of building the computer. He approved the development of work on the housing and computer power supply.
Apple II was presented by Jobs and Wozniak at the West Coast Computer Faire in 1977 and became a real hit. It also became the first consumer product sold by Apple Computer, Inc. The Apple II model was also the first Apple II series computer that was developed until November 1993.
The successor to Apple II was the modernized Apple II Plus model, which hit the market in June 1979.
