The invention of the Personal Computer History
Model 5100 was succeeded by the 5110 and 5120 before IBM invented what we know as the IBM Personal Computer PC (Model 5150). Although the 5100 series was early series of the IBM PC, the older systems and the 5150 IBM PC had nothing in common things. The PC that IBM turned out was more closely related to the IBM System 23 Data Master, an office computer system introduced in 1980. In fact, many of the engineers who developed the IBM PC has basically worked on the DataMaster.
In 1976, The Apple company introduced the computer Apple-I, which originally sold for $666.66. The selling price was a free amount selected by one of Apple’s cofounders, Steve Jobs. This system was built of the main circuit board with a piece of plywood, a casing and power supply were not attached. Only 200 of these personal computers were made. Recent auctions of Apple-I computers have seen these uncommon systems selling for prices ranging from $387,750 to $905,000. The Apple-II, introduced in 1977, it helped to set the standard quality for nearly all of the important microcomputers to follow, including the IBM PC.
