Unisys
Unisys Corporation is a global technology solutions company founded in 1986 and headquartered in Blue Bell, Pennsylvania. The company provides cloud, AI, digital workplace, logistics, and enterprise computing services. History Founding Unisys’ history dates back to 1873 with E. Remington & Sons and the introduction of the first commercially viable typewriter to use the QWERTY keyboard layout. Over a hundred years later, the company became known as Unisys in 1986 through the merger of Mainframe computer, mainframe corporations Sperry Corporation, Sperry and Burroughs Corporation, Burroughs, with Burroughs buying Sperry for $4.8 billion. The new company's name was chosen from over 31,000 submissions in an internal competition when Christian Machen submitted the word "Unisys", which was composed of parts of the words "united", "information", and "systems". The merger was the largest in the computer industry at the time and made Unisys the second-largest computer company wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burroughs MCP
The MCP (Master Control Program) is the operating system of the Burroughs B5000/B5500/B5700 and the B6500 and successors, including the Unisys Clearpath/MCP systems. MCP was originally written in 1961 in ESPOL (Executive Systems Problem Oriented Language). In the 1970s, MCP was converted to NEWP which was a better structured, more robust, and more secure form of ESPOL. The MCP was a leader in many areas, including: the first operating system to manage multiple processors, the first commercial implementation of virtual memory, and the first OS written exclusively in a high-level language. History In 1961, the MCP was the first OS written exclusively in a high-level language (HLL). The Burroughs Large System ( B5000 and successors) were unique in that they were designed with the expectation that all software, including system software, would be written in an HLL rather than in assembly language, which was a unique and innovative approach in 1961. Unlike IBM, which faced ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
