Tatung Einstein
The Tatung Einstein was an eight-bit home/personal computer produced by Taiwanese corporation Tatung, designed in Bradford, England at Tatung's research laboratories and assembled in Bridgnorth and Telford, England. It was aimed primarily at small businesses. History The Tatung Einstein TC-01 was released in the United Kingdom in the summer of 1984, and 5,000 were exported to Taipei later that year. A Tatung monitor (monochrome or colour) and dot matrix printer were also available as options, plus external disc drives and an 80 column display card. It was also capable of running ZX Spectrum software with the "Speculator" addon. More expensive than most of its rivals, the Einstein was popular with contemporary programmers as a development machine but was commercially unsuccessful. A later revised version, called the Tatung Einstein 256 and released in 1985, suffered a similar fate. Design The machine was physically large, with an option for one or two built-in three-inc ...

Bridgnorth
Bridgnorth is a town in Shropshire, England. The River Severn splits it into High Town and Low Town, the upper town on the right bank and the lower on the left bank of the River Severn. The population at the 2011 Census was 12,079. History Bridgnorth is named after a bridge over the River Severn, which was built further north than an earlier bridge at Quatford. The earliest historical reference to the town is in 895, when it is recorded that the Danes created a camp at ''Cwatbridge''; subsequently in 912, Æthelfleda constructed a mound on the west bank of the River Severn, or possibly on the site of Bridgnorth Castle, as part of an offensive against the Danes. Earliest names for Bridgnorth include Brigge, Brug and Bruges, all referring to its position on the Severn. After the Norman conquest, William I granted the manor of Bridgnorth to Roger de Montgomerie. The town itself was not created until 1101, when Robert of Bellême, 3rd Earl of Shrewsbury, the son of Roger de M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BASIC Programming Language
BASIC (Beginners' All-purpose Symbolic Instruction Code) is a family of General-purpose programming language, general-purpose, high-level programming languages designed for ease of use. Dartmouth BASIC, The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963. They wanted to enable students in non-scientific fields to use computers. At the time, nearly all computers required writing custom software, which only scientists and mathematicians tended to learn. In addition to the program language, Kemeny and Kurtz developed the Dartmouth Time Sharing System (DTSS), which allowed multiple users to edit and run BASIC programs simultaneously on remote terminals. This general model became very popular on minicomputer systems like the PDP-11 and Data General Nova in the late 1960s and early 1970s. Hewlett-Packard produced an entire computer line for this method of operation, introducing the HP2000 series in the late 1960s and continuing sales int ...

Torquay
Torquay ( ) is a seaside town in Devon, England, part of the unitary authority area of Torbay. It lies south of the county town of Exeter and east-north-east of Plymouth, on the north of Tor Bay, adjoining the neighbouring town of Paignton on the west of the bay and across from the fishing port of Brixham. The town's economy, like Brixham's, was initially based upon fishing and agriculture, but in the early 19th century it began to develop into a fashionable seaside resort. Later, as the town's fame spread, it was popular with Victorian society. Renowned for its mild climate, the town earned the nickname the English Riviera. The writer Agatha Christie was born in the town and lived at Ashfield in Torquay during her early years. There is an "Agatha Christie Mile", a tour with plaques dedicated to her life and work. The poet Elizabeth Barrett Browning lived in the town from 1837 to 1841 on the recommendation of her doctor in an attempt to cure her of a disease which is ...

Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...

Machine Code Monitor
A machine code monitor ( machine language monitor) is software that allows a user to enter commands to view and change memory locations on a computer, with options to load and save memory contents from/to secondary storage. Some full-featured machine code monitors provide detailed control ("single-stepping") of the execution of machine language programs (much like a debugger), and include absolute-address code assembly and disassembly capabilities. Motorola published the MIKBUG ROM monitor for the 6800 in 1973 and the BUFFALO ROM monitor for the 68HC11. Machine code monitors became popular during the home computer era of the 1970s and 1980s and were sometimes available as resident firmware in some computers (e.g., the built-in monitors in the Commodore 128, Heathkit H89 and Zenith laptops). Often, computer manufacturers rely on their ROM-resident monitors to permit users to reconfigure their computers following installation of upgrade hardware, such as expanded main memory, ...

Compact Audio Cassette
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge and reel ...

ZX Spectrum
The ZX Spectrum () is an 8-bit computing, 8-bit home computer that was developed by Sinclair Research. It was released in the United Kingdom on 23 April 1982, and became Britain's best-selling microcomputer. Referred to during development as the ''ZX81 Colour'' and ''ZX82'', it was launched as the ''ZX Spectrum'' to highlight the machine's colour display, which differed from the black and white display of its predecessor, the ZX81. The Spectrum was released as six different models, ranging from the entry level with 16 Kilobyte, KB RAM released in 1982 to the ZX Spectrum +3 with 128 KB RAM and built in floppy disk drive in 1987; altogether they sold over 5 million units worldwide (not counting List of ZX Spectrum clones, unofficial clones). The Spectrum was among the first home computers in the United Kingdom aimed at a mainstream audience, and it thus had similar significance to the Commodore 64 in the US and the Thomson MO5 in France. The introduction of the ZX Spect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disk Enclosure
A disk enclosure is a specialized casing designed to hold and power disk drives while providing a mechanism to allow them to communicate to one or more separate computers. Drive enclosures provide power to the drives therein and convert the data sent across their native data bus into a format usable by an external connection on the computer to which it is connected. In some cases, the conversion is as trivial as carrying a signal between different connector types. In others, it is complicated enough to require a separate embedded system to retransmit data over connector and signal of a different standard. Factory-assembled external hard disk drives, external DVD-ROM drives, and others consist of a storage device in a disk enclosure. Benefits Key benefits to using external disk enclosures include: *Adding additional storage space and media types to small form factor and laptop computers, as well as sealed embedded systems such as digital video recorders and video game con ...

Dot Matrix Printer
A dot matrix printer is an impact printer that prints using a fixed number of pins or wires. Typically the pins or wires are arranged in one or several vertical columns. The pins strike an ink-coated ribbon and force contact between the ribbon and the paper, so that each pin makes a small dot on the paper. The combination of these dots forms a dot matrix image. They were also known as serial dot matrix printers. While inkjet and laser printers technically exhibit dot matrix printing, they work differently than impact "dot matrix printers" and can deposit ink or toner at higher dot resolutions more quickly, with less inherent noise. The impact printer has the ability to make copies using multi-part forms, unlike an inkjet or laser printer. History In the 1970s and 1980s, dot matrix impact printers were generally considered the best combination of cost and versatility, and until the 1990s were by far the most common form of printer used with personal and home computers.

Monochrome
A monochrome or monochromatic image, object or palette is composed of one color (or values of one color). Images using only shades of grey are called grayscale (typically digital) or black-and-white (typically analog). In physics, monochromatic light refers to electromagnetic radiation that contains a narrow band of wavelengths, which is a distinct concept. Application Of an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-red. It may also refer to sepia displaying tones from light tan to dark brown or cyanotype ("blueprint") images, and early photographic methods such as daguerreotypes, ambrotypes, and tintypes, each of which may be used to produce a monochromatic image. In computing, monochrome has two meanings: *it may mean having only one color which is either on or off (also known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
