Magazines Established In 1913
A magazine is a periodical publication, print or digital, produced on a regular schedule, that contains any of a variety of subject-oriented textual and visual content forms. Magazines are generally financed by advertising, purchase price, prepaid subscriptions, or by a combination of the three. They are categorised by their frequency of publication (i.e., as weeklies, monthlies, quarterlies, etc.), their target audiences (e.g., women's and trade magazines), their subjects of focus (e.g., popular science and religious), and their tones or approach (e.g., works of satire or humor). Appearance on the cover of print magazines has historically been understood to convey a place of honor or distinction to an individual or event. Term origin and definition Origin The etymology of the word "magazine" suggests derivation from the Arabic (), the broken plural of () meaning "depot, storehouse" (originally military storehouse); that comes to English via Middle French and Italian .

Science And Technology Magazines Published In The United Kingdom
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into twoor threemajor branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Egypt and Mesopotamia (). Their contributions to mathematics, astronomy, and medicine entered and shaped the Greek natural philo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivor Catt
Ivor Catt (born 1935) is a British electronics engineer known principally for his alternative theories of electromagnetism. He received a B.A. degree from Cambridge University, and has won the ''Electronic Design'' magazine's "best product of the year" award on 26 October 1989, after £16 million funding.

PSI Comp 80 (computer)
The PSI Comp 80 was a home computer sold by Powertran starting in 1979. It was sold in the form of a kit of parts for a cased single-board home computer system. The system was based on a Z80 microprocessor addressing a mixture of 8 KB of system RAM and EPROM, plus 2 KB of video RAM. It used a National Semiconductor MM57109N as a mathematical co-processor to speed up calculations. History and specifications In 1979, the British magazine ''Wireless World'' published the technical details for a "Scientific Computer". Shortly afterward the British firm Powertran used this design for their implementation, which they called the PSI Comp 80. Ahead of its time, it incorporated a number crunching coprocessor and a novel language embedded in EPROM called Basic Using Reverse Polish - BURP. The monochrome Video Display Controller could simultaneously display combinations of 32 lines of 64 characters, and 128 x 64 resolution graphics by either displaying a normal character or a " pseudo ...

Nascom
The Nascom 1 and 2 were single-board computer kits issued in the United Kingdom in 1977 and 1979, respectively, based on the Zilog Z80 and including a keyboard and video interface, a serial port that could be used to store data on a tape cassette using the Kansas City standard, and two 8-bit parallel ports. At that time, including a full keyboard and video display interface was uncommon, as most microcomputer kits were then delivered with only a hexadecimal keypad and seven-segment display. To minimize cost, the buyer had to assemble a Nascom by hand-soldering about 3,000 joints on the single circuit board. Later on, a pre-built, cased machine named Nascom 3 was available; this used the Nascom 2 board. History The history of Nascom starts with the history of John A. Marshall. Marshall was the "& Son" of "A Marshall & Son (London) Ltd", an electronic component retailer whose adverts were a regular feature in hobby electronics magazines from as early as 1967. Marshall was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teletext
Teletext, or broadcast teletext, is a standard for displaying text and rudimentary graphics on suitably equipped television sets. Teletext sends data in the broadcast signal, hidden in the invisible vertical blanking interval area at the top and bottom of the screen. The teletext decoder in the television buffers this information as a series of "pages", each given a number. The user can display chosen pages using their remote control. In broad terms, it can be considered as Videotex, a system for the delivery of information to a user in a computer-like format, typically displayed on a television or a dumb terminal, but that designation is usually reserved for systems that provide bi-directional communication, such as Prestel or Minitel. Teletext was created in the United Kingdom in the early 1970s by John Adams, Philips' lead designer for video display units to provide closed captioning to television shows for the hearing impaired. Public teletext information services were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

EL84
The EL84 is a vacuum tube of the power pentode type. It is used in the power-output stages of audio amplifiers, most commonly now in guitar amplifiers, but originally in radios. The EL84 is smaller and more sensitive than the octal 6V6 that was widely used around the world until the 1960s. An interchangeable North American type is the ''6BQ5'' (the RETMA tube designation name for the EL84). The EL84 was developed to eliminate the need for a driver tube in radios, so it has rather more gain than is usual in a power pentode. Eliminating a preamplifier triode in radios made them cheaper. Manufacturers were quick to adopt it in general use, and they are found in many old European tube-radios and other audio equipment. A single EL84 was used in low-cost equipment, and a push–pull pair for lower distortion and higher power. In common with all 'E' prefix tubes, using the Mullard–Philips tube designation, it has a heater voltage of 6.3V. It can produce 17W output in Class AB1 i ...
