Ethernet. From these inventions, Xerox PARC created the Xerox Alto in 1973, a small minicomputer similar to a modern workstation or personal computer. This machine can be considered the first true Personal Computer, given its versatile combination of a cathode-ray-type screen, mouse-type pointing device, and a QWERTY-type alphanumeric keyboard. But the Alto was never commercially sold, as Xerox itself could not see the sales potential of it. It was, however, installed in Xerox's own offices, worldwide and those of the US Government and military, who could see the potential. Within these sites the individual workstations were connected together by Xerox's own unique LAN, The Ethernet. Data was sent around this system of heavy, yellow, low loss coaxial cable using the packet data system. In addition, PARC also developed one of the earliest internetworking protocol suites, the PARC Universal Packet (PUP). In 1979, Steve Jobs made a deal with Xerox's venture capital division: He would let them invest $1 million in exchange for a look at the technology they were working on. Jobs and the others saw the commercial potential of the WIMP (Window, Icon, Menu, and Pointing device) system and redirected development of the Apple Lisa to incorporate these technologies. Jobs is quoted as saying, "They just had no idea what they had." In 1980, Jobs invited several key PARC researchers to join his company so that they could fully develop and implement their ideas. In 1981, Xerox released a system similar to the Alto, the Xerox Star. It was the first commercial system to incorporate technologies that have subsequently become commonplace in personal computers, such as a bitmapped display, window-based GUI, mouse, Ethernet networking, file servers, print servers and e-mail. The Xerox Star and its successor the Xerox Daybreak, despite their technological breakthroughs, did not sell well due to its high price, costing $16,000 per unit. A typical Xerox Star-based office, complete with network and printers, would have cost $100,000. In the mid-1980s, Apple considered buying Xerox; however, a deal was never reached. Apple instead bought rights to the Alto GUI and adapted it into a more affordable personal computer, aimed towards the business and education markets. The Apple Macintosh was released in 1984, and was the first personal computer to popularize the GUI and mouse among the public. In 2002, PARC was spun off into an independent wholly-owned subsidiary of Xerox. Chief executives Products and services Xerox manufactures
