One Per Desk
The One Per Desk, or OPD, was an innovative hybrid personal computer/telecommunications terminal based on the hardware of the Sinclair QL. The One Per Desk was built by International Computers Limited (ICL) and launched in the UK in 1984. It was the result of a collaborative project between ICL, Sinclair Research and British Telecom begun in 1983, originally intended to incorporate Sinclair's flat-screen CRT technology. Rebadged versions of the OPD were sold in the United Kingdom as the Merlin Tonto and as the Computerphone by Telecom Australia and the New Zealand Post Office. The initial orders placed for the One Per Desk were worth £4.5 million (for 1500 units) from British Telecom and £8 million from Telecom Australia, with ICL focusing on telecommunications providers as the means to reach small- and medium-sized businesses. Hardware From the QL, the OPD borrowed the 68008 CPU, ZX8301/ 8302 ULAs, 128 KB of RAM and dual Microdrives (re-engineered by ICL fo ...

International Computers Limited
International Computers Limited (ICL) was a British computer hardware, computer software and computer services company that operated from 1968 until 2002. It was formed through a merger of International Computers and Tabulators (ICT), English Electric Computers (EEC) and Elliott Automation in 1968. The company's most successful product line was the ICL 2900 Series range of mainframe computers. In later years, ICL diversified its product line but the bulk of its profits always came from its mainframe customers. New ventures included marketing a range of powerful IBM clones made by Fujitsu, various minicomputer and personal computer ranges and (more successfully) a range of retail point-of-sale equipment and back-office software. Although it had significant sales overseas, ICL's mainframe business was dominated by large contracts from the UK public sector, including Post Office Ltd, the Inland Revenue, the Department for Work and Pensions and the Ministry of Defence. It also had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microcontroller
A microcontroller (MCU for ''microcontroller unit'', often also MC, UC, or μC) is a small computer on a single VLSI integrated circuit (IC) chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips. In modern terminology, a microcontroller is similar to, but less sophisticated than, a system on a chip (SoC). An SoC may connect the external microcontroller chips as the motherboard components, but an SoC usually integrates the advanced peripherals like graphics processing unit (GPU) and Wi-Fi interface controller as its internal microcontroller unit circuits. Microcontrollers are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bingo (UK)
Bingo is a game of probability in which players mark off numbers on cards as the numbers are drawn randomly by a caller, the winner being the first person to mark off all their numbers. Bingo, also previously known in the UK as Housey-Housey, became increasingly popular across the UK following the Betting and Gaming Act 1960 with more purpose-built bingo halls opened every year until 2005. Since 2005, bingo halls have seen a marked decline in revenues and the closure of many halls. The number of bingo clubs in Britain has dropped from nearly 600 in 2005 to under 400 as of January 2014. These closures are blamed on high taxes, the smoking ban, and the rise in online gambling, amongst other things. Bingo played in the UK (90-ball bingo) is not to be confused with bingo played in the US ( 75-ball bingo), as the tickets and the calling are slightly different. In Quebec, this game is called Kinzo. In India, it is known as Tambola. History The game itself, not originally called bin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Satellite Computing
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...
