83-472: 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 an "element" (frequently called a "typeball", or less formally, a "golf ball") that rotated and pivoted to
166-442: A " stish " or a " starsh ", it would be a blend. Furthermore, when blends are formed by shortening established compounds or phrases, they can be considered clipped compounds , such as romcom for romantic comedy . Blends of two or more words may be classified from each of three viewpoints: morphotactic, morphonological, and morphosemantic. Blends may be classified morphotactically into two kinds: total and partial . In
249-412: A belt connected to a two-part shaft located roughly halfway through the machine. The cycle shaft on the left side powers the tilt and rotate mechanism. The operational shaft on the right side powers functions such as spacing, backspacing, and case shifting, as well as serving as a governor, limiting the left-to-right speed with which the carrier moves. A series of spring clutches power the cams which provide
332-485: A carrier wheel. Like the Varityper with which it competed, the original machine required that material be typed twice if the output was to be justified . The first time was to measure the length of the line and count the spaces, recording measurements read from a special dial on the right margin. The second time it was typed, the operator set the measurements into the dial to set justification for each line. The process
415-549: A complete set, but no user needed to; a publication that could use the somewhat bookish, academic Aldine Roman would probably not have much use for the Classified News or Copperplate Gothic (used most often for formal invitations and business cards). The following font families were available for the Composer: In contrast to the Selectric typewriter, only IBM made elements for the standard typefaces usually used with
498-535: A form suitable for carrying on horseback; (now esp.) one in the form of a stiff leather case hinged at the back to open into two equal parts". According to The American Heritage Dictionary of the English Language ( AHD ), the etymology of the word is the French porte-manteau , from porter , "to carry", and manteau , "cloak" (from Old French mantel , from Latin mantellum ). According to

As an example of an exocentric attributive blend, Fruitopia may metaphorically take the buyer to a fruity utopia (and not a utopian fruit); however, it is not a utopia but a drink. Coordinate blends (also called associative or portmanteau blends) combine two words having equal status, and have two heads. Thus brunch
664-414: A latch to disengage from a cam, allowing it to move an additional input into the whiffletree that subtracts five units of rotation from any negative logic inputs. An additional "low velocity" selector latch is also engaged by certain keys (e.g. period and underscore) which require a reduced striking force so as not to cut the paper; this selector latch engages the low velocity control cam follower, which pulls
747-770: A little-known variant of the MC/ST called the Mag Card Executive. Shortly after the introduction of the Selectric III, IBM introduced the IBM Personal Typewriter , a hybrid model that used the widely available 88-character “golfball” type elements and correction tape of the Selectric II, but used the newer Selectric III’s ribbon cartridges. Limited to a single fixed pitch (only 12 CPI, though either pica or elite type elements could be used),
830-421: A pigment designed to be easily removed from paper. There were two types of correction tapes: the transparent and slightly adhesive "Lift-Off" tape (for use with the correctable film ribbon), or the white "Cover-Up" tape (for cloth, Tech-3, and carbon film ribbons). The correction tape was changed independently from the typing ribbon. The correction key (an extra key at the bottom right of the keyboard) backspaced
913-403: A reduced cost. Italic and bold were available for some but not all font "families". Up to three point sizes existed for each style and variety. In contrast with the Selectric, a change of type style usually required purchase of a family of type balls, rather than just a single one. Just as in the days of metal type, no single printing shop had every typeface, it was also rare for a user to possess

#1732780728371996-486: A total blend, each of the words creating the blend is reduced to a mere splinter. Some linguists limit blends to these (perhaps with additional conditions): for example, Ingo Plag considers "proper blends" to be total blends that semantically are coordinate, the remainder being "shortened compounds". Commonly for English blends, the beginning of one word is followed by the end of another: Much less commonly in English,
1079-520: A toy typewriter produced earlier by Marx Toys . IBM bought the rights to the design. The element and carriage mechanism was similar to the design of the Teletype Model 26 and later, which used a rotating cylinder that moved along a fixed platen. The mechanism that positions the typing element ("ball") takes a binary input, and converts this to character offsets using two mechanical digital-to-analog converters, which are " whiffletree " linkages of
1162-459: A variety of font styles ranging from eight points to fourteen points. Material prepared on a properly-adjusted machine by a skillful operator and printed onto baryta ( barium sulfate -coated) paper "would take an expert to tell ...

For example, the term Việt Cộng is derived from the first syllables of "Việt Nam" (Vietnam) and "Cộng sản" (communist). Many corporate brand names , trademarks, and initiatives, as well as names of corporations and organizations themselves, are blends. For example, Wiktionary , one of Misplaced Pages 's sister projects,

The word portmanteau was introduced in this sense by Lewis Carroll in the book Through the Looking-Glass (1871), where Humpty Dumpty explains to Alice the coinage of unusual words used in " Jabberwocky ". Slithy means "slimy and lithe" and mimsy means "miserable and flimsy". Humpty Dumpty explains to Alice the practice of combining words in various ways, comparing it to

It can occur with three components: The phonological overlap need not also be orthographic: If the phonological but non-orthographic overlap encompasses
1577-699: Is neither a breakfasty lunch nor a lunchtime breakfast but instead some hybrid of breakfast and lunch; Oxbridge is equally Oxford and Cambridge universities. This too parallels (conventional, non-blend) compounds: an actor–director is equally an actor and a director. Two kinds of coordinate blends are particularly conspicuous: those that combine (near‑) synonyms: and those that combine (near‑) opposites: Blending can also apply to roots rather than words, for instance in Israeli Hebrew : "There are two possible etymological analyses for Israeli Hebrew כספר kaspár 'bank clerk, teller'. The first
1660-433: Is represented by various shorter substitutes – ‑otel ... – which I shall call splinters. Words containing splinters I shall call blends". Thus, at least one of the parts of a blend, strictly speaking, is not a complete morpheme , but instead a mere splinter or leftover word fragment. For instance, starfish is a compound, not a blend, of star and fish , as it includes both words in full. However, if it were called

The second is that it is a quasi- portmanteau word which blends כסף késef 'money' and (Hebrew>) Israeli ספר √spr 'count'. Israeli Hebrew כספר kaspár started as a brand name but soon entered the common language. Even if the second analysis is the correct one,

In modern French, a porte-manteau is a clothes valet , a coat-tree or similar article of furniture for hanging up jackets, hats, umbrellas and the like. An occasional synonym for "portmanteau word"
1909-536: The Selectric III , followed by several other Selectric models, some of them word processors or typesetters instead of typewriters, but by then the rest of the industry had caught up, and IBM's new models did not dominate the market the way the first Selectric had. This was to be expected, as by the late 1970s the Selectric typewriter's dominance was under assault from both 35–45 character per second proportional-spacing electronic typewriters with inbuilt memory, like

2075-555: The "Composer" equivalents. This allowed much of the time-consuming manual transcription work and proofreading to be performed on less-expensive equipment, while a final high-quality output could be printed on the Composer. For a number of years after its introduction, the Selectric Composer was considered a highly desirable, powerful desk-sized cold type setting system, affordable by small businesses and organizations. It
2158-497: The "MT/ST" and "MC/ST", respectively. The MC/ST was also available in a "communicating" version which could emulate an IBM 2741 terminal or run its native Correspondence Code. These featured electronically interfaced typing mechanisms and keyboards and a magnetic storage device (either tape in a cartridge, or a magnetic-coated card the same size as an 80-column punched card) for recording, editing, and replaying typed material at ca. 12–15 characters per second. These machines were among
2241-674: The 1980s by word processors and general-purpose computers. The Electronic Selectric Composer was released in January 1975 by the office division of IBM; it was an automated, direct impression composition unit with a built in memory of up to 8,000 characters. Other features included automatic justification with one keyboarding, automatic print out of columns in one play out and reformatting ease with capability of justified, “rag” right, flush left or virtually any configuration specified. It also had over 125 interchangeable printing fonts (type heads) in sizes from 3 to 12 points. In 1980, IBM introduced
2324-506: The 800 from Xerox based on Diablo's " daisywheels " and OEMs of Qume which had similar printwheel technology, and CRT-based systems from AES, Lexitron, Vydek, Wang and Xerox. In addition, IBM had already (c. 1977) brought to market the CRT-based Office System/6 and 5520 , both of which used the new 6640 inkjet printer capable of 96 characters per second with two paper trays and sophisticated envelope handling, and
2407-546: The 96-character keyboard was an optional feature. Fitting the additional keys onto the keyboard required shrinking the Return and Backspace keys. This was annoying to many typists, so it was not the default configuration. The keytops on Selectric III and Electronic Typewriters were larger and more square than those on earlier Selectrics. Some versions of the Electronic Typewriter, the original Model 50, and
2490-435: The Composer. GP, which made elements for the Selectric typewriter, did make one Composer element in an Old English typeface. In 1967, a " Magnetic Tape Selectric Composer " appeared, and in 1978, a "Magnetic Card Selectric Composer". The "Electronic Composer" (with approximately 5000 characters of internal memory, similar to the later Magnetic Card model but without external storage) was marketed from 1975. All these models used
2573-748: The IBM Mag Card II Typewriter was announced, providing space for up to 8,000 characters in electronic memory. IBM also sold a tape reader (IBM 2495) that could be connected to 360 series mainframes, and would read the MT/ST tapes. Thus a document typed on an MT/ST Selectric could also be entered into a mainframe data file. In 1966, IBM released the Selectric Composer for use in phototypesetting applications. This highly-modified (and much more-expensive) Selectric produced camera-ready justified copy using proportional fonts in

2656-479: The Selectric II, intended to eliminate the need for typists to use cover-up tape, "white-out" correction fluid, or typewriter erasers. The carriage on this machine held both the main typing ribbon cartridge and two small spools for a correction ribbon. A new ribbon type, the Correctable Film ribbon, was introduced at the same time. This produced typing quality equal to the carbon film ribbon, but with
2739-667: The Selectric line with the IBM Wheelwriter in 1984, and transferred its typewriter business to the newly formed Lexmark in 1991. The Selectric typewriter was introduced on 31 July 1961. Its industrial design is credited to influential American designer Eliot Noyes . Noyes had worked on a number of design projects for IBM ; prior to his work on the Selectric, he had been commissioned in 1956 by Thomas J. Watson Jr. to create IBM's first house style : these influential efforts, in which Noyes collaborated with Paul Rand , Marcel Breuer , and Charles Eames , have been referred to as
2822-618: The Selectric's 25th anniversary, in 1986, a total of more than 13 million machines had been made and sold. By the 1970s and 1980s, the typewriter market had matured under the market dominance of large companies in Europe and the United States. Eventually the Selectric would face direct major competition from electronic typewriters designed and manufactured in Asia, including Brother Industries and Silver Seiko Ltd. of Japan. IBM replaced
2905-606: The Selectric. The Wheelwriter featured a replaceable daisy wheel cartridge, had electronic memory, and offered many word processing features. The Selectric's keyboard layout put the underscore, hyphen, and single and double quote characters as pairs on their own keys – an arrangement which had already been used on many earlier electric typewriters , including IBM's own Model A onwards. The traditional layout of mechanical typewriters had offered these characters as shifts from digit keys. Electric typewriter designers had made this change because smaller characters need to hit

Information was intercepted by detecting the movements of metal bars inside the typewriter (the "latch interposers") by means of magnetometers . The data were then compressed and transmitted in bursts. The bugs were installed in Selectric II and III models. IBM introduced the IBM Wheelwriter in 1984 as a successor to
3071-502: The beginning of one word may be followed by the beginning of another: Some linguists do not regard beginning+beginning concatenations as blends, instead calling them complex clippings, clipping compounds or clipped compounds . Unusually in English, the end of one word may be followed by the end of another: A splinter of one word may replace part of another, as in three coined by Lewis Carroll in " Jabberwocky ": They are sometimes termed intercalative blends; these words are among
3154-423: The carriage by one space and also put the machine in a mode wherein the next character typed would use the correction tape instead of the normal ribbon, and furthermore would not advance the carriage. The typist would press (and release) the correction key and then re-type the erroneous character, either lifting it off the page or (if using other than the correctable ribbon) covering it with white-out powder, then type
3237-524: The clutch on the cycle shaft for one cycle, providing power to the filter shaft, whose lobes thrust the interposer towards the front (operator end) of the machine. When the interposer moves, each of its lugs engages one of a set of bars (selector bails) that run from left to right across the keyboard mechanism. In a machine with a North American keyboard, there are five "negative logic" selector bails (two for tilt and three for rotation), and one "positive logic" bail (called "minus five") for accessing characters in
3320-439: The correct character. Any number of mistakes could be corrected this way, but the process was entirely manual, as the machine had no memory of the typed characters. The Selectric II had been announced and was in production when a cam timing issue was identified. The type head ball would strike the character and leave small remnants of ink of the character that was meant to be erased. A lower level engineer, Joe L. Vaughan, overheard
3403-491: 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

3486-434: The desired character. Each interposer also has a tab that slots in between loose steel balls in a race, the size of balls and race selected precisely to leave a total gap barely larger than the width of the interposer tab, such that only one interposer tab can fit in the free space and thus only one letter can be selected at a time. When the interposer is depressed, it engages a metal bar (cycle clutch latch link) that connects
3569-418: The drive shaft (which is rotating) to move the ends of the links in the whiffletree linkage, which sums (adds together) the amounts ("weights") of movement corresponding to the selected bits. The sum of the weighted inputs is the required movement of the typing element. There are two sets of similar mechanisms, one for tilt, one for rotate. The typing element has four rows of 22 characters. By tilting and rotating
3652-420: The element by exactly half a turn. This is accomplished by moving the right-hand rotate pulley via the shift arm, using a cam mounted on the end of the operation shaft; the additional cable tension adds 180° to any rotation from the whiffletree. Portmanteau In linguistics , a blend —also known as a blend word , lexical blend , or portmanteau —is a word formed by combining the meanings, and parts of

The rotate pulley under the tilt ring is connected through a universal joint (called a "dog bone", which it resembles) to the center of the tilt ring. The element is spring-latched onto that central post. The element rotates counter-clockwise when
3818-453: The element to the location of a character, the element can be thrust against the ribbon and platen, leaving an imprint of the chosen character. Tilt and rotate movements are transferred to the carrier (the mechanism that supports the element), which moves across the page, by two taut metal tapes, one for tilt and one for rotate. The tilt and rotate tapes are both anchored to the right side of the carrier. They both wrap around separate pulleys at
3901-599: The final syllable ר- -ár apparently facilitated nativization since it was regarded as the Hebrew suffix ר- -år (probably of Persian pedigree), which usually refers to craftsmen and professionals, for instance as in Mendele Mocher Sforim 's coinage סמרטוטר smartutár 'rag-dealer'." Blending may occur with an error in lexical selection , the process by which a speaker uses his semantic knowledge to choose words. Lewis Carroll's explanation, which gave rise to
3984-674: The first "house style" program in American business. The Selectric remained unchanged until 1971 when the Selectric II was introduced. The original design was thereafter referred to as the Selectric I . These machines used the same 88-character typing elements. However they differed from each other in many respects: In 1973 the Correcting Selectric II was announced. It added an internal correction feature to
4067-415: The first to provide word processing capability in any form. They used the same elements as ordinary office Selectrics. In 1972, the "Mag Card Executive" was offered. Like IBM's earlier typebar-based "Executive" models this offered proportional spacing, but unlike them, based on multiples of a 1/60" unit size with up to seven units per character, instead of a unit size of 1/32", 1/36", or 1/45", depending on
4150-461: The gradual drifting together of words over time due to them commonly appearing together in sequence, such as do not naturally becoming don't (phonologically, / d uː n ɒ t / becoming / d oʊ n t / ). A blend also differs from a compound , which fully preserves the stems of the original words. The British lecturer Valerie Adams's 1973 Introduction to Modern English Word-Formation explains that "In words such as motel ..., hotel
4233-403: The ingredients is the head and the other is attributive. A porta-light is a portable light, not a 'light-emitting' or light portability; light is the head. A snobject is a snobbery-satisfying object and not an objective or other kind of snob; object is the head. As is also true for (conventional, non-blend) attributive compounds (among which bathroom , for example, is a kind of room, not

#17327807283714316-588: The later Model 65 and 85, could use 96-character elements with proportionally-spaced typestyles in addition to 10-pitch and 12-pitch typestyles. This proportional spacing was based on a unit of 1/60 of an inch, since 10-pitch characters took six such units, and 12-pitch characters took five such units. (Many daisywheel typewriters, offering similar capabilities, also had daisywheel elements for 15-pitch typing, using four units per character.) The proportional typestyles offered for these typewriters had previously been offered, along with some others, on 88-character elements for
4399-401: The low velocity cable connected to the cam in the carrier, causing the low velocity lobe to be used instead of the usual high velocity lobe. Additionally, punctuation marks are deliberately placed about the ball so the maximum amount of energy is used to position the element prior to striking, further reducing the impact. The selector latches that remain engaged with the latch bail cause cams on
4482-495: The morphemes or phonemes stay in the same position within the syllable. Some languages, like Japanese , encourage the shortening and merging of borrowed foreign words (as in gairaigo ), because they are long or difficult to pronounce in the target language. For example, karaoke , a combination of the Japanese word kara (meaning empty ) and the clipped form oke of the English loanword "orchestra" (J. ōkesutora , オーケストラ ),
4565-399: The motion needed to perform functions such as backspacing. When the typist presses a key, a pawl on the key lever depresses a matching metal bar (interposer) for that key. The interposer, which is oriented front to back in the machine, has one or more short projections (lugs) protruding from its bottom edge. Each interposer has a unique combination of lugs, corresponding to the binary code for
4648-486: The opposite direction of rotation. Each negative logic selector bail that is displaced by the interposer in turn pulls a latch interposer and link which causes a selector latch near the cycle shaft to be pulled away from the latch bail. The latches pulled away in this manner are disengaged for the rest of the cycle, while the remaining latches take part in character selection, hence the term "negative logic". The minus five selector bail pulls an interposer and link which causes
4731-495: The original "portmanteaus" for which this meaning of the word was created. In a partial blend, one entire word is concatenated with a splinter from another. Some linguists do not recognize these as blends. An entire word may be followed by a splinter: A splinter may be followed by an entire word: An entire word may replace part of another: These have also been called sandwich words, and classed among intercalative blends. (When two words are combined in their entirety,
4814-436: The paper vertically while the typeball and ribbon mechanism moved horizontally across the paper. The Selectric mechanism was notable for using internal mechanical binary coding and two mechanical digital-to-analog converters , called whiffletree linkages, to select the character to be typed. Selectrics and their descendants eventually captured 75 percent of the United States market for electric typewriters used in business. By
4897-511: The paper with less force than most, and pairing these characters in this way avoided the need to adjust the force based on shift state. About a decade later, this character pairing was formalized in the American Standards Association X4.14-1971 standard as typewriter pairing (colloquially a typewriter-paired keyboard ), along with bit-paired keyboards . Typewriter pairing became the only supported arrangement in
4980-453: The result is considered a compound word rather than a blend. For example, bagpipe is a compound, not a blend, of bag and pipe. ) Morphologically, blends fall into two kinds: overlapping and non-overlapping . Overlapping blends are those for which the ingredients' consonants, vowels or even syllables overlap to some extent. The overlap can be of different kinds. These are also called haplologic blends. There may be an overlap that

The tapes extend across the machine behind the carrier, and then wrap around two separate pulleys at the left side of the frame. The tilt tape is then anchored to a small, quarter-circle pulley which, through a link, tips the tilt ring (the device to which

#17327807283715146-434: The rotate tape is tightened. The spiral "clock" spring underneath the rotate pulley rotates the element in the clockwise direction. As the carrier moves across the page (such as when it returns), the tapes travel over their pulleys, but the spring-loaded pulleys on the ball carrier do not pivot or rotate. To position the ball, both of the pulleys on the left side of the frame are moved by their whiffletree linkages, actuated by
5229-462: The same Selectric Composer output (printing) mechanism. However, the magnetic or internal storage allowed these improved models to avoid the need to type in justified text twice, or to manually set the mechanism for justification of each line. Furthermore, tapes or cards originally recorded on the much less-expensive and easier-to-operate Selectric typewriter versions, the MT/ST or MC/ST, could be read by
5312-435: The same sentence, slowed work down and was a source of owner dissatisfaction. (In typical use, Selectric elements were changed infrequently.) The small plastic balls were themselves somewhat fragile and not designed to withstand frequent handling. Nevertheless, the Composer allowed much more flexible use of different typefonts, allowing small businesses and organizations to approach the capabilities of professional typesetters, at

When the tilt pulley is moved, it tips the tilt ring to the appropriate location. When it moves, the tape rotates the spring-loaded pulley on the ball carrier independent of the carrier's location on the page. Case is shifted from lowercase to uppercase (and associated shifted punctuation symbols) by rotating
5478-541: The size of the typestyle, with up to five units per character as was used on the original "Executive" typewriters. Unlike the various "Selectric Composer" models, there was no provision for setting the machine to vary the letter and word spacing to create justified copy. Some of the fonts originally offered with the Mag Card Executive would later be made available for the Model 50 electronic typewriter, which supported proportional spacing with 96-character elements. In April 1973,
5561-399: The sounds, of two or more words together. English examples include smog , coined by blending smoke and fog , as well as motel , from motor ( motorist ) and hotel . A blend is similar to a contraction . On the one hand, mainstream blends tend to be formed at a particular historical moment followed by a rapid rise in popularity. Contractions, on the other hand, are formed by
5644-497: The successor X4.23-1982 standard. The Selectric also added a dedicated key for 1 / ! . The typist no longer had to use a lowercase L , nor overstrike the single quote and period characters, as had been the practice on most earlier typewriters. These changes were later copied by the IBM Model D electric typewriter (1967), and later still by DEC 's VT52 terminal (1975) and the original IBM PC (1981). Typewriter pairing
5727-484: The then-common type of luggage , which opens into two equal parts: You see it's like a portmanteau—there are two meanings packed up into one word. In his introduction to his 1876 poem The Hunting of the Snark , Carroll again uses portmanteau when discussing lexical selection: Humpty Dumpty's theory, of two meanings packed into one word like a portmanteau, seems to me the right explanation for all. For instance, take

Tab stops could be positioned only at intervals of one-sixth of an inch, or one pica .

In addition to Univers, a Century , Times Roman -like font, and later an "Aldine" font ( Bembo ) were available, as was a Symbols font. However, the Composer, with its relatively small market, never had anything like

Parts were machined for a change to the cam mechanism without introducing any further delays to production, and the fix was a success. Vaughan was recognized for the accomplishment in 1974. In 1964 IBM introduced the " Magnetic Tape Selectric Typewriter " and in 1969, a "Magnetic Card Selectric Typewriter". These were sometimes referred to as
6059-413: The top plastic surface and the legend "96", which always appears along with the font name and pitch. The 96- and 88-character elements are mechanically incompatible with each other (they will not fit on each other's machines) and 96-character elements were not available in as many fonts as the older 88-character types. Most Selectric IIIs and Electronic Typewriters had keys only for 92 printable characters;
6142-462: The two words "fuming" and "furious". Make up your mind that you will say both words, but leave it unsettled which you will say first … if you have the rarest of gifts, a perfectly balanced mind, you will say "frumious". In then-contemporary English, a portmanteau was a suitcase that opened into two equal sections. According to the OED Online , a portmanteau is a "case or bag for carrying clothing and other belongings when travelling; (originally) one of
6225-451: The type used for adding and subtracting in linkage-type mechanical analog computers. (The nomenclature used by IBM Office Product Customer Engineers and in IBM maintenance publications for the machine's "whiffletrees" is "Rotate and Tilt Differentials".) Every character position on the element has a two-part binary code, one for tilt and one for rotate. The motor at the back of the machine drives
6308-571: The typewriter was significantly less expensive than either the Selectric II or Selectric III and targeted the home and consumer markets. There is at least one known case of the Selectric exploited as a covert listening device of the type known as a " keyboard logger ". In 1984, bugs were discovered in at least 16 Selectric typewriters in the U.S. Embassy in Moscow and the U.S. Consulate in Leningrad. The highly sophisticated devices were planted by
6391-406: The use of 'portmanteau' for such combinations, was: Humpty Dumpty's theory, of two meanings packed into one word like a portmanteau, seems to me the right explanation for all. For instance, take the two words "fuming" and "furious." Make up your mind that you will say both words ... you will say "frumious." The errors are based on similarity of meanings, rather than phonological similarities, and
6474-435: The variety of typefaces available as there were for the Selectric (see below). Each font required separate elements for italic and bold versions, and a separate set of roman/italic/bold balls was required for each font size. Not all typefaces were available in bold and italic in every size for every font. Bold italic, condensed, and light fonts were not available. The need to change elements frequently, sometimes multiple times in
6557-542: The whole of the shorter ingredient, as in then the effect depends on orthography alone. (They are also called orthographic blends. ) An orthographic overlap need not also be phonological: For some linguists, an overlap is a condition for a blend. Non-overlapping blends (also called substitution blends) have no overlap, whether phonological or orthographic: Morphosemantically, blends fall into two kinds: attributive and coordinate . Attributive blends (also called syntactic or telescope blends) are those in which one of
6640-609: Was about to introduce Qume-based printers for the existing System/6 range and the new Displaywriter launched in June 1980 and described by IBM as "not your father's Selectric". Nevertheless, IBM had a large installed base of Selectric typewriters and to retain customer loyalty it made sense to introduce updated models. The Selectric III featured a 96-character element vs. the previous 88-character element. IBM's series of "Electronic Typewriters" used this same 96-character element. The 96-character elements can be identified by yellow printing on
6723-484: Was seen on many other computer keyboards, particularly the influential Model M (1985). The new layout was not universal, however. Internationally, many layouts kept the bit-paired arrangement. This is easily visible in ⇧ Shift + 2 yielding " , as on the standard UK layout. The bit-paired symbols are also retained in the Japanese keyboard layout . Mechanically, the Selectric borrowed some design elements from
6806-456: Was tedious and slow, but did provide a way to get camera-ready, proportionally spaced, justified copy from a desk-sized, affordable machine. The elements for the Selectric Composer would physically fit on a Selectric and vice versa, but were not interchangeable because the characters were arranged and positioned differently around the element. Selectric Composer elements can be distinguished by their colored index arrow (the color indicated which of
6889-485: Was usually leased, including a service contract for the skilled labor required to fix and adjust it. The Selectric Composer was accorded respect and affection among small publishers, unrivaled until the appearance of the Apple Macintosh , laser printer , and desktop publishing software. Ultimately the system proved a transitional product, as it was displaced by cheaper and faster phototypesetting, and then in
