IBM Electric Typewriter
The IBM Electric were an early series of electric typewriters that IBM manufactured, starting in the mid-1930s. They used the conventional moving carriage and typebar mechanism, as opposed to the fixed carriage and type ball used in the IBM Selectric, introduced in 1961. After 1944, each model came in both "Standard" and "Executive" versions, the latter featuring proportional spacing. History The IBM Electromatic typewriter was the first electric typewriter to enjoy long-term commercial success. Unlike the later IBM Selectric typewriter, this typewriter model used a conventional moving carriage and typebar mechanism. The history of the Electromatic goes back to 1924, when the North East Electric Company received patent rights for the power roller from James Smathers. At that time, the company was selling electric motors, and wanted to get into the typewriter business. They reached an arrangement with Remington, securing a contract for 2,500 machines in 1925. N.

IBM Selectric Typewriter
The IBM Selectric (a portmanteau of "selective" and "electric") was a highly successful line of electric typewriters introduced by IBM on 31 July 1961. Instead of the "basket" of individual typebars that swung up to strike the ribbon and page in a typical typewriter of the period, the Selectric had a chrome-plated plastic "element" (frequently called a "typeball", or less formally, a "golf ball") that rotated and tilted to the correct position before striking the paper. The element could be easily interchanged to use different fonts within the same document typed on the same typewriter, resurrecting a capability which had been pioneered by typewriters such as the Hammond and Blickensderfer in the late 19th century. The Selectric also replaced the traditional typewriter's horizontally moving carriage with a roller (platen) that turned to advance the paper vertically while the typeball and ribbon mechanism moved horizontally across the paper. The Selectric mechanism was notable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JOHNNIAC
The JOHNNIAC was an early computer built in 1953 by the RAND Corporation (not Remington Rand, maker of the contemporaneous UNIVAC I computer) and based on the von Neumann architecture that had been pioneered on the IAS machine. It was named in honor of von Neumann, short for '' John von Neumann Numerical Integrator and Automatic Computer''. After being rescued from the scrap heap twice, the machine is currently at the Computer History Museum in Mountain View, California. Like the IAS machine, JOHNNIAC used 40-bit words, and included 1024 words of Selectron tube main memory, each holding 256 bits of data. Two instructions were stored in every word in 20-bit subwords consisting of an 8-bit instruction and a 12-bit address, the instructions being operated in series with the left subword running first. The initial machine had 83 instructions. A single register, named ''A'', supplied an accumulator and the machine also featured a register named ''Q'', for quotient. There was only one ...

Serif
In typography, a serif () is a small line or stroke regularly attached to the end of a larger stroke in a letter or symbol within a particular font or family of fonts. A typeface or "font family" making use of serifs is called a serif typeface (or serifed typeface), and a typeface that does not include them is sans-serif. Some typography sources refer to sans-serif typefaces as "grotesque" (in German language, German, ) or "Gothic" (although this often refers to blackletter type as well). In German usage, the term Antiqua (typeface class), Antiqua is used more broadly for serif types. Serif typefaces can be broadly classified into one of four subgroups: Serif#Old-style, Old-style, Serif#Transitional, Transitional, Serif#Didone, Didone, and Serif#Slab serif, Slab serif, in order of first emergence. Origins and etymology Serifs originated from the first official Greek writings on stone and in Latin alphabet with Roman square capitals, inscriptional lettering—words carved into s ...

Font
In metal typesetting, a font is a particular size, weight and style of a ''typeface'', defined as the set of fonts that share an overall design. For instance, the typeface Bauer Bodoni (shown in the figure) includes fonts " Roman" (or "regular"), "" and ""; each of these exists in a variety of sizes. In the digital description of fonts ( computer fonts), the terms "font" and "typeface" are often used interchangeably. For example, when used in computers, each style is stored in a separate digital font file. In both traditional typesetting and computing, the word "font" refers to the delivery mechanism of an instance of the typeface. In traditional typesetting, the font would be made from metal or wood type: to compose a page may require multiple fonts from the typeface or even multiple typefaces. Spelling and etymology The word ''font'' (US) or ''fount'' (traditional UK, CAN; in any case pronounced ) derives from Middle French ''fonte'', meaning "cast iron". The term re ...

Typesetting
Typesetting is the composition of text for publication, display, or distribution by means of arranging physical ''type'' (or ''sort'') in mechanical systems or '' glyphs'' in digital systems representing '' characters'' (letters and other symbols).Dictionary.com Unabridged. Random House, Inc. 23 December 2009Dictionary.reference.com/ref> Stored types are retrieved and ordered according to a language's orthography for visual display. Typesetting requires one or more fonts (which are widely but erroneously confused with and substituted for typefaces). One significant effect of typesetting was that authorship of works could be spotted more easily, making it difficult for copiers who have not gained permission. Pre-digital era Manual typesetting During much of the letterpress era, movable type was composed by hand for each page by workers called compositors. A tray with many dividers, called a case, contained cast metal '' sorts'', each with a single letter or symbol, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Justification (typesetting)
In typesetting and page layout, alignment or range is the setting of text flow or image placement relative to a page, column (measure), table cell, or tab (and often to an image above it or under it). The type alignment setting is sometimes referred to as text alignment, text justification, or type justification. The edge of a page or column is known as a ''margin'', and a gap between columns is known as a ''gutter''. Basic variations There are four basic typographic alignments: * flush left—the text is aligned along the left margin or gutter, also known as ''left-aligned'', ''ragged right'' or ''ranged left''; * flush right—the text is aligned along the right margin or gutter, also known as ''right-aligned'', ''ragged left'' or ''ranged right''; * justified—text is aligned along the left margin, with letter-spacing and word-spacing adjusted so that the text falls flush with both margins, also known as ''fully justified'' or ''full justification''; * centered—text is ali ...

Point (typography)
In typography, the point is the smallest unit of measure. It is used for measuring font size, leading, and other items on a printed page. The size of the point has varied throughout printing's history. Since the 18th century, the size of a point has been between 0.18 and 0.4 millimeters. Following the advent of desktop publishing in the 1980s and 1990s, digital printing has largely supplanted the letterpress printing and has established the desktop publishing (DTP) point as the ''de facto'' standard. The DTP point is defined as of an inch (or exactly 0.352 mm) and, as with earlier American point sizes, is considered to be of a pica. In metal type, the point size of a font describes the height of the metal body on which that font's characters were cast. In digital type, letters of a computer font are designed around an imaginary space called an '' em square''. When a point size of a font is specified, the font is scaled so that its em square has a side length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sentence Spacing
Sentence spacing concerns how Space (punctuation), spaces are inserted between sentences in typeset Written language, text and is a matter of typographical convention (norm), convention. Since the introduction of movable type, movable-type printing in Europe, various sentence spacing conventions have been used in languages with a Latin script, Latin alphabet. These include a normal word space (as between the words in a sentence), a single enlarged space, and two full spaces. Until the 20th century, publishing houses and printers in many countries used additional space between sentences. There were exceptions to this traditional spacing method—some printers used spacing between sentences that was no wider than word spacing. This was ''History of sentence spacing#French and English spacing, French spacing''—a term synonymous with single-space sentence spacing until the late 20th century. With the introduction of the typewriter in the late 19th century, typists used two spaces bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IBM 1130
The IBM 1130 Computing System, introduced in 1965, was IBM's least expensive computer at that time. A binary 16-bit machine, it was marketed to price-sensitive, computing-intensive technical markets, like education and engineering, succeeding the decimal IBM 1620 in that market segment. Typical installations included a 1 megabyte disk drive that stored the operating system, compilers and object programs, with program source generated and maintained on punched cards. Fortran was the most common programming language used, but several others, including APL, were available. The 1130 was also used as an intelligent front-end for attaching an IBM 2250 Graphics Display Unit, or as remote job entry (RJE) workstation, connected to a System/360 mainframe. Description The total production run of the 1130 has been estimated at 10,000. The 1130 holds a place in computing history because it (and its non-IBM clones) gave many people their first direct interaction with a computer. Its pric ...
