[6] [7] The first machines were introduced on March 1, 1973, [8] and in limited production starting one decade before Xerox's designs inspired Apple to release the first mass-market GUI computers. The Alto is contained in a relatively small cabinet and uses a custom central processing unit (CPU) built from multiple SSI and MSI integrated circuits .
The first machines in the series are the 16-bit Sigma 2 and the 32-bit Sigma 7; the Sigma 7 was the first 32-bit computer released by SDS. At the time, the only competition for the Sigma 7 was the IBM 360. Memory size increments for all SDS/XDS/Xerox computers are stated in kwords, not kbytes.
Front of the Xerox Sigma 9. On display at the Living Computer Museum in Seattle, Washington. The Xerox Sigma 9, also known as the XDS Sigma 9, is a high-speed, general purpose computer. Xerox first became interested in office automation through computers in 1969 and purchased Scientific Data Systems or SDS.
The Xerox 500 series is a discontinued line of computers from Xerox Data Systems (XDS) introduced in the early 1970s as backward-compatible upgrades for the Sigma series machines. Although orders for the Xerox 530 were deemed "encouraging" as of January 1974, [ 1 ] the systems had failed to gain traction by the time Xerox sold its Data Systems ...
Xerox was founded in 1906 in Rochester, New York, as the Haloid Photographic Company. [11] It manufactured photographic paper and equipment. In 1938, Chester Carlson, a physicist working independently, invented a process for printing images using an electrically charged photoconductor-coated metal plate [12] and dry powder "toner".
The Xerox Star workstation, officially named Xerox Star 8010 Information System, is the first commercial personal computer to incorporate technologies that have since become standard in personal computers, including a bitmapped display, a window-based graphical user interface, icons, folders, mouse (two-button), Ethernet networking, file servers, print servers, and email.
The Xerox NoteTaker is a portable computer developed at Xerox PARC in Palo Alto, California, in 1978. Although it did not enter production, and only around ten prototypes were built, it strongly influenced the design of the later Osborne 1 and Compaq Portable computers.
[c] The winds, and hence, the blowing snow, eased somewhat on January 31, the sixth day since the first blizzard began, although all areas still experienced frigid temperatures approximating −15 °C (5 °F), taking into account the wind chill, plus received still more snow—4.8 centimetres (1.9 in) in London, 11.9 centimetres (4.7 in) in ...
