BBC Computer
The BBC Microcomputer System, or BBC Micro, is a family of microcomputers developed and manufactured by Acorn Computers in the early 1980s as part of the BBC's Computer Literacy Project. Launched in December 1981, it was showcased across several educational BBC television programmes, such as ''The Computer Programme'' (1982), ''Making the Most of the Micro'' and ''Computers in Control'' (both 1983), and ''Micro Live'' (1985). Created in response to the BBC's call for bids for a microcomputer to complement its broadcasts and printed material, Acorn secured the contract with its rapidly prototyped “Proton” system, which was subsequently renamed the BBC Micro. Although it was announced towards the end of 1981, production issues initially delayed the fulfilment of many orders, causing deliveries to spill over into 1982. Nicknamed the “Beeb”, it soon became a fixture in British schools, advancing the BBC’s goal of improving computer literacy. Renowned for its strong build q ...

Motorola 6800
The 6800 ("''sixty-eight hundred''") is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System (later dubbed ''68xx'') that also included serial and parallel interface ICs, RAM, ROM and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year. "Motorola's M6800 microcomputer system, which can operate from a single 5-volt supply, is moving out of the sampling stage and into full production." The small-quantity price of the MC6800 is . The MC6820 PIA cost . American Microsystems was licensed as the second source. The 6800 has a 16-bit address bus that can directly access of memory and an 8-bit bi-directional data bus. It has 72 instructions with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

VOIP
Voice over Internet Protocol (VoIP), also known as IP telephony, is a set of technologies used primarily for voice communication sessions over Internet Protocol (IP) networks, such as the Internet. VoIP enables voice calls to be transmitted as data packets, facilitating various methods of voice communication, including traditional applications like Skype, Microsoft Teams, Google Voice, and VoIP phones. Regular telephones can also be used for VoIP by connecting them to the Internet via analog telephone adapters (ATAs), which convert traditional telephone signals into digital data packets that can be transmitted over IP networks. The broader terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the delivery of voice and other communication services, such as fax, SMS, and voice messaging, over the Internet, in contrast to the traditional public switched telephone network (PSTN), commonly known as plain old telephone service (POTS) ...

Short Message Service
Short Message Service, commonly abbreviated as SMS, is a text messaging service component of most telephone, Internet and mobile device systems. It uses standardized communication protocols that let mobile phones exchange short text messages, typically transmitted over cellular networks. Developed as part of the GSM standards, and based on the SS7 signalling protocol, SMS rolled out on digital cellular networks starting in 1993 and was originally intended for customers to receive alerts from their carrier/operator. The service allows users to send and receive text messages of up to 160 characters, originally to and from GSM phones and later also CDMA and Digital AMPS; it has since been defined and supported on newer networks, including present-day 5G ones. Using SMS gateways, messages can be transmitted over the Internet through an SMSC, allowing communication to computers, fixed landlines, and satellite. MMS was later introduced as an upgrade to SMS with "picture mess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Computer World
''Personal Computer World'' (''PCW'') (February 1978 - June 2009) was the first British computer magazine. Although for at least the last decade it contained a high proportion of Windows PC content (reflecting the state of the IT field), the magazine's title was not intended as a specific reference to this. At its inception in 1978 'personal computer' was still a generic term (the Apple II, Commodore PET, PET 2001 and TRS-80 had been launched as personal computers in 1977.) The magazine came out before the Wintel (or IBM PC compatible) platform existed; the original IBM PC itself was introduced in 1981. Similarly, the magazine was unrelated to the Amstrad PCW.

SWTPC 6800
The SWTPC 6800 Computer System, simply referred to as SWTPC 6800, is an early microcomputer developed by the Southwest Technical Products Corporation and introduced in 1975. It was built around the Motorola 6800 microprocessor, from which it gets its name. The SWTPC 6800 was one of the first microcomputers based around the Motorola 6800. The SWTPC 6800 is the progenitor of the widely used and broadly supported SS-50 bus. The SWTPC 6800 became one of the most popular 6800-based systems of its time, owing to its ease of use and ample documentation. Though rudimentary, the MIKBUG resident monitor built into ROM allows the immediate entry of program data after power-up, as opposed to other microcomputers of its day which required bootstrapping such software. Southwest Technical Products introduced the SWTPC 6800 in November 1975 for US$450 () in kit form only. Any contemporary ASCII terminal can be used to interface with the SWTPC 6800. SWTPC sold their own television-set-based te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printed Circuit Board
A printed circuit board (PCB), also called printed wiring board (PWB), is a Lamination, laminated sandwich structure of electrical conduction, conductive and Insulator (electricity), insulating layers, each with a pattern of traces, planes and other features (similar to wires on a flat surface) Chemical milling, etched from one or more sheet layers of copper laminated onto or between sheet layers of a non-conductive substrate. PCBs are used to connect or Electrical wiring, "wire" Electronic component, components to one another in an electronic circuit. Electrical components may be fixed to conductive pads on the outer layers, generally by soldering, which both electrically connects and mechanically fastens the components to the board. Another manufacturing process adds Via (electronics), vias, metal-lined drilled holes that enable electrical interconnections between conductive layers, to boards with more than a single side. Printed circuit boards are used in nearly all e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data General Nova
The Nova is a series of 16-bit computing, 16-bit minicomputers released by the American company Data General. The Nova family was very popular in the 1970s and ultimately sold tens of thousands of units. The first model, known simply as "Nova", was released in 1969. The Nova was packaged into a single Rack unit, 3U rack-mount case and had enough computing power to handle most simple tasks. The Nova became popular in science laboratories around the world. It was followed the next year by the SuperNOVA, which ran roughly four times as fast, making it the fastest mini for several years. Introduced during a period of rapid progress in integrated circuit (or "microchip") design, the line went through several upgrades over the next five years, introducing the 800 and 1200, the Nova 2, Nova 3, and ultimately the Nova 4. A single-chip implementation was also introduced as the microNOVA in 1977, but did not see widespread use as the market moved to new microprocessor designs. Fairchil ...

Hansard
''Hansard'' is the transcripts of parliamentary debates in Britain and many Commonwealth of Nations, Commonwealth countries. It is named after Thomas Curson Hansard (1776–1833), a London printer and publisher, who was the first official printer to the Parliament of the United Kingdom, Parliament at Westminster. Origins Though the history of the ''Hansard'' began in the British Parliament, each of Britain's colonies developed a separate and distinctive history. Before 1771, the British Parliament had long been a highly secretive body. The official record of the actions of the House was publicly available but there was no record of the debates. The publication of remarks made in the House became a breach of parliamentary privilege, punishable by the two Houses of Parliament (UK), Houses of Parliament. As the populace became interested in parliamentary debates, more independent newspapers began publishing unofficial accounts of them. The many penalties implemented by the governmen ...
