History and development of Apple-1: In April 1976 three young entrepreneurs – Steve Jobs, Steve Wozniak and Ronald Wayne – founded the Apple Computer Co. to sell a new kit-form personal computer, which was nothing less than the first ready-to-use PC. Although the Apple-1 was not the earliest of the first generation PCs, it captured computer users' interest in an unprecedented way. From home-grown origins in the family garage, Apple Inc. has developed into the world's largest publicly traded corporation. The Apple-1 personal computer was its first and most iconic product. – Apple-1 was one of the first PCs with integrated graphics functionality and keyboard connection. As the computer did not have an operating system, but a so-called 'monitor program' that provided the interface between keyboard entry, memory and video display, more sophisticated software system such as Basic had to be loaded via cassette. – The cassette-interface card was offered by Apple as an optional extra. Peripheral equipment such as power pack and cassette recorder were supplied by the user. The redwood-mounted keyboard and rack-mount for the motherboard seen here are a typical indication of the way Apple's first users customized their machines. – The first fifty Apple-1 computers were supplied to the "Byte Shop", a pioneering computer retail chain opened by Paul Terrel of Mountview, California, in 1975. Terrel, who already knew of Steve Jobs through the "Homebrew Computer Club" in Silicon Valley, purchased a batch of 50 units for $ 500 a piece in April 1976. Terrel was quick to realize that the new breed of computer users desired a functioning computer and not simply a kit. – It was also said to be Terrel's suggestion of combining the image of an apple with the Byte Shop's first slogan "Byte into an Apple" that prompted Wozniak and Jobs to discontinue Ron Wayne's original pen-and-ink drawing of Sir Isaac Newton under an apple tree already early in 1977. The launch of the Apple II in June 1977 coincided with the introduction of Rob Janoff's instantly recognizable logo that is still in use today.
