Apple II - starting the personal computer boom. In April 1977, the Apple II was introduced to the public at the West coast Computer Faire market, where Apple had rented the largest booth just opposite the entrance.
Wozniak s technological wonder was a great success and the first orders were already made. The Apple II was the first true personal computer. It was the first microcomputer able to generate color graphics and the first with BASIC in ROM and included a keyboard, power supply and an attractive lightweight and beige plastic case, which would become standard for subsequent PCs. The Apple II was more sophisticated than any microcomputer before, and represented a machine, which could be worked with effectively.
Steve Wozniak had put all his engineering savvy into it, and had created a computer he would like to own. The Apple II was given a rapturous welcome in the public. In 1977, the company sold more than 4,000 computers, which were priced at 1,300, and grew rapidly. Programs and data for the Apple II were stored on cassette tapes. But this common way of storage turned out to be quite unreliable and awkward.
Mike Markkula saw the future in floppy disks, which had been developed by IBM in the early 1970s, and asked Wozniak to design a disk drive for the Apple II. Woz took the challenge and finished in record time only one month. His final design was brilliant he developed a new technique self-sync and.
