Apple ][

The Apple II (stylized as Apple ][) was an 8-bit home computer, one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak (Steve Jobs oversaw the development of the Apple II’s unusual case and Rod Holt developed the unique power supply). It was introduced in 1977 at the West Coast Computer Faire by Jobs and was the first consumer product sold by Apple Computer. It had a MOS Technology processor running at just 1MHz with 4KB of RAM. Today’s iPhones have processors running at 1,800 times the clock speed with 500,000 times more RAM. Photo: Ralph Morse/Time & Life Pictures/Getty Images.
