a history of modern computing 2nd edition phần 5

các Sigma 7, chi phí khoảng $ 1 kết nối Huntsville của Palevsky phục vụ công ty của ông. Vào đầu những năm 1960 các cơ sở đã chuyển từ quân đội đến NASA, nơi, dưới sự lãnh đạo của Wernher von Braun, "tên lửa" đội được giao nhiệm vụ phát triển tên lửa đẩy sẽ mất người đàn ông mặt trăng và quay trở lại. | The Go-Go Years and the System 360 1961-1975 167 like the UNIVAC 1108 were the natural descendants of the IBM 7090. They were both sold and leased and prices ranged up to 250 000. In 1967 SDS announced a more powerful computer the Sigma 7 which cost around 1 Palevsky s Huntsville connections served his company well. By the early 1960s the facilities were transferred from the Army to NASA where under the leadership of Wernher von Braun the rocket team was charged with developing the boosters that would take men to the Moon and back. IBM hardware handled the bulk of the Center s chores but SDS computers were installed to do real-time simulations and tests of the rockets guidance systems. Drawing on a relationship established when Palevsky was working for Bendix Helmut Hoelzer and Charles Bradshaw chose to install SDS computers after becoming disillusioned with RCA machines they had initially ordered for that SDS s fortunes rose and fell with the Apollo program even as men were walking on the Moon in 1969 NASA was cutting back and having to plan for operations on smaller budgets. Xerox bought Palevsky s company at a value ten times its earnings expecting that SDS now the XDS division would grow. Some journalists claimed that Palevsky knew he was selling a company with no future but Palevsky stated under oath for the United States vs. IBM antitrust trial that he believed other The division did not grow and Xerox closed XDS in 1975. SDS had no adequate plan for expanding its products beyond the narrow niche it occupied again revealing the wisdom of IBM s System 360 philosophy. But Xerox must also shoulder the blame. The company had built up the finest research laboratory for computing in the world in Palo Alto California but it failed to fit these two pieces of its organization together much less fit both of them into its core business of selling copiers. Software Houses A final measure of how the System 360 redefined the computer industry
