History.

TTL was invented in 1961 by James L. Buie of TRW, which declared it, "particularly suited to the newly developing integrated circuit design technology." The original name for TTL was "transistor-coupled transistor logic" (TCTL). The first commercial integrated-circuit TTL devices were manufactured by Sylvania in 1963, called the Sylvania Universal High-Level Logic family (SUHL). The Sylvania parts were used in the controls of the Phoenix missile. TTL became popular with electronic systems designers after Texas Instruments introduced the 5400 series of ICs, with military temperature range, in 1964 and the later 7400 series, specified over a narrower range and with inexpensive plastic packages, in 1966.  The Texas Instruments 7400 family became an industry standard. Compatible parts were made by Motorola, AMD, Fairchild, Intel, Intersil, Signetics, Mullard, Siemens, SGS-Thomson, Rifa, National Semiconductor, and many other companies, even in the Eastern Bloc (Soviet Union, GDR, Poland, Czechoslovakia, Hungary, Romania - for details see 7400 series). Not only did others make compatible TTL parts, but compatible parts were made using many other circuit technologies as well. At least one manufacturer, IBM, produced non-compatible TTL circuits for its own use; IBM used the technology in the IBM System/38, IBM 4300, and IBM 3081.  The term "TTL" is applied to many successive generations of bipolar logic, with gradual improvements in speed and power consumption over about two decades. The most recently introduced family 74Fxx is still sold today (as of 2019), and was widely used into the late 90s. 74AS/ALS Advanced Schottky was introduced in 1985. As of 2008, Texas Instruments continues to supply the more general-purpose chips in numerous obsolete technology families, albeit at increased prices. Typically, TTL chips integrate no more than a few hundred transistors each. Functions within a single package generally range from a few logic gates to a microprocessor bit-slice. TTL also became important because its low cost made digital techniques economically practical for tasks previously done by analog methods.  The Kenbak-1, ancestor of the first personal computers, used TTL for its CPU instead of a microprocessor chip, which was not available in 1971. The Datapoint 2200 from 1970 used TTL components for its CPU and was the basis for the 8008 and later the x86 instruction set. The 1973 Xerox Alto and 1981 Star workstations, which introduced the graphical user interface, used TTL circuits integrated at the level of Arithmetic logic units (ALUs) and bitslices, respectively. Most computers used TTL-compatible "glue logic" between larger chips well into the 1990s. Until the advent of programmable logic, discrete bipolar logic was used to prototype and emulate microarchitectures under development.

Implementation.

Fundamental TTL gate.

TTL inputs are the emitters of bipolar transistors. In the case of NAND inputs, the inputs are the emitters of multiple-emitter transistors, functionally equivalent to multiple transistors where the bases and collectors are tied together. The output is buffered by a common emitter amplifier.  Inputs both logical ones. When all the inputs are held at high voltage, the base–emitter junctions of the multiple-emitter transistor are reverse-biased. Unlike DTL, a small “collector” current (approximately 10μA) is drawn by each of the inputs. This is because the transistor is in reverse-active mode. An approximately constant current flows from the positive rail, through the resistor and into the base of the multiple emitter transistor. This current passes through the base–emitter junction of the output transistor, allowing it to conduct and pulling the output voltage low (logical zero).  An input logical zero. Note that the base–collector junction of the multiple-emitter transistor and the base–emitter junction of the output transistor are in series between the bottom of the resistor and ground. If one input voltage becomes zero, the corresponding base–emitter junction of the multiple-emitter transistor is in parallel with these two junctions. A phenomenon called current steering means that when two voltage-stable elements with different threshold voltages are connected in parallel, the current flows through the path with the smaller threshold voltage. That is, current flows out of this input and into the zero (low) voltage source. As a result, no current flows through the base of the output transistor, causing it to stop conducting and the output voltage becomes high (logical one). During the transition the input transistor is briefly in its active region; so it draws a large current away from the base of the output transistor and thus quickly discharges its base. This is a critical advantage of TTL over DTL that speeds up the transition over a diode input structure.  The main disadvantage of TTL with a simple output stage is the relatively high output resistance at output logical "1" that is completely determined by the output collector resistor. It limits the number of inputs that can be connected (the fanout). Some advantage of the simple output stage is the high voltage level (up to V) of the output logical "1" when the output is not loaded.  A common variation omits the collector resistor of the output transistor, making an open-collector output. This allows the designer to fabricate logic by connecting the open-collector outputs of several logic gates together and providing a single external pull-up resistor. If any of the logic gates becomes logic low (transistor conducting), the combined output will be low. Examples of this type of gate are the 7401 and 7403 series. Open-collector outputs of some gates have a higher maximum voltage, such as 15 V for the 7426, useful when driving other than TTL loads.

TTL with a "totem-pole" output stage.

To solve the problem with the high output resistance of the simple output stage the second schematic adds to this a "totem-pole" ("push–pull") output. It consists of the two n-p-n transistors V and V, the "lifting" diode V and the current-limiting resistor R (see the figure on the right). It is driven by applying the same "current steering" idea as above.  When V is "off", V is "off" as well and V operates in active region as a voltage follower producing high output voltage (logical "1").  When V is "on", it activates V, driving low voltage (logical "0") to the output. Again there is a current-steering effect: the series combination of V's C-E junction and V's B-E junction is in parallel with the series of V B-E, V's anode-cathode junction, and V C-E. The second series combination has the higher threshold voltage, so no current flows through it, i.e. V base current is deprived. Transistor V turns "off" and it does not impact on the output.  In the middle of the transition, the resistor R limits the current flowing directly through the series connected transistor V, diode V and transistor V that are all conducting. It also limits the output current in the case of output logical "1" and short connection to the ground. The strength of the gate may be increased without proportionally affecting the power consumption by removing the pull-up and pull-down resistors from the output stage.  The main advantage of TTL with a "totem-pole" output stage is the low output resistance at output logical "1". It is determined by the upper output transistor V operating in active region as an emitter follower. The resistor R does not increase the output resistance since it is connected in the V collector and its influence is compensated by the negative feedback. A disadvantage of the "totem-pole" output stage is the decreased voltage level (no more than 3.5 V) of the output logical "1" (even if the output is unloaded). The reason of this reduction are the voltage drops across the V base–emitter and V anode–cathode junctions.

Interfacing considerations.

Like DTL, TTL is a "current-sinking logic" since a current must be drawn from inputs to bring them to a logic 0 voltage level. The driving stage must absorb up to 1.6 mA from a standard TTL input while not allowing the voltage to rise to more than 0.4 volts.. The output stage of the most common TTL gates is specified to function correctly when driving up to 10 standard input stages (a fanout of 10). TTL inputs are sometimes simply left floating to provide a logical "1", though this usage is not recommended.  Standard TTL circuits operate with a 5-volt power supply. A TTL input signal is defined as "low" when between 0 V and 0.8 V with respect to the ground terminal, and "high" when between 2 V and V (5 V), and if a voltage signal ranging between 0.8 V and 2.0 V is sent into the input of a TTL gate, there is no certain response from the gate and therefore it is considered "uncertain" (precise logic levels vary slightly between sub-types and by temperature). TTL outputs are typically restricted to narrower limits of between 0.0 V and 0.4 V for a "low" and between 2.4 V and V for a "high", providing at least 0.4 V of noise immunity. Standardization of the TTL levels is so ubiquitous that complex circuit boards often contain TTL chips made by many different manufacturers selected for availability and cost, compatibility being assured. Two circuit board units off the same assembly line on different successive days or weeks might have a different mix of brands of chips in the same positions on the board; repair is possible with chips manufactured years later than original components. Within usefully broad limits, logic gates can be treated as ideal Boolean devices without concern for electrical limitations. The 0.4V noise margins are adequate because of the low output impedance of the driver stage, that is, a large amount of noise power superimposed on the output is needed to drive an input into an undefined region.  In some cases (e.g., when the output of a TTL logic gate needs to be used for driving the input of a CMOS gate), the voltage level of the "totem-pole" output stage at output logical "1" can be increased closer to V by connecting an external resistor between the V collector and the positive rail. It pulls up the V cathode and cuts-off the diode. However, this technique actually converts the sophisticated "totem-pole" output into a simple output stage having significant output resistance when driving a high level (determined by the external resistor).

Packaging.

Like most integrated circuits of the period 1963–1990, commercial TTL devices are usually packaged in dual in-line packages (DIPs), usually with 14 to 24 pins, for through-hole or socket mounting. Epoxy plastic (PDIP) packages were often used for commercial temperature range components, while ceramic packages (CDIP) were used for military temperature range parts.  Beam-lead chip dies without packages were made for assembly into larger arrays as hybrid integrated circuits. Parts for military and aerospace applications were packaged in flatpacks, a form of surface-mount package, with leads suitable for welding or soldering to printed circuit boards. Today, many TTL-compatible devices are available in surface-mount packages, which are available in a wider array of types than through-hole packages.  TTL is particularly well suited to bipolar integrated circuits because additional inputs to a gate merely required additional emitters on a shared base region of the input transistor. If individually packaged transistors were used, the cost of all the transistors would discourage one from using such an input structure. But in an integrated circuit, the additional emitters for extra gate inputs add only a small area.  At least one computer manufacturer, IBM, built its own flip chip integrated circuits with TTL; these chips were mounted on ceramic multi-chip modules.

Comparison with other logic families.

TTL devices consume substantially more power than equivalent CMOS devices at rest, but power consumption does not increase with clock speed as rapidly as for CMOS devices. Compared to contemporary ECL circuits, TTL uses less power and has easier design rules but is substantially slower. Designers can combine ECL and TTL devices in the same system to achieve best overall performance and economy, but level-shifting devices are required between the two logic families. TTL is less sensitive to damage from electrostatic discharge than early CMOS devices.  Due to the output structure of TTL devices, the output impedance is asymmetrical between the high and low state, making them unsuitable for driving transmission lines. This drawback is usually overcome by buffering the outputs with special line-driver devices where signals need to be sent through cables. ECL, by virtue of its symmetric low-impedance output structure, does not have this drawback.  The TTL "totem-pole" output structure often has a momentary overlap when both the upper and lower transistors are conducting, resulting in a substantial pulse of current drawn from the power supply. These pulses can couple in unexpected ways between multiple integrated circuit packages, resulting in reduced noise margin and lower performance. TTL systems usually have a decoupling capacitor for every one or two IC packages, so that a current pulse from one TTL chip does not momentarily reduce the supply voltage to another.  Several manufacturers now supply CMOS logic equivalents with TTL-compatible input and output levels, usually bearing part numbers similar to the equivalent TTL component and with the same pinouts. For example, the 74HCT00 series provides many drop-in replacements for bipolar 7400 series parts, but uses CMOS technology.

Sub-types.

Successive generations of technology produced compatible parts with improved power consumption or switching speed, or both. Although vendors uniformly marketed these various product lines as TTL with Schottky diodes, some of the underlying circuits, such as used in the LS family, could rather be considered DTL.  Variations of and successors to the basic TTL family, which has a typical gate propagation delay of 10ns and a power dissipation of 10 mW per gate, for a power–delay product (PDP) or switching energy of about 100 pJ, include:  Most manufacturers offer commercial and extended temperature ranges: for example Texas Instruments 7400 series parts are rated from 0 to 70 °C, and 5400 series devices over the military-specification temperature range of −55 to +125 °C.  Special quality levels and high-reliability parts are available for military and aerospace applications.  Radiation-hardened devices (for example from the SNJ54 series) are offered for space applications.

Applications.

Before the advent of VLSI devices, TTL integrated circuits were a standard method of construction for the processors of minicomputer and mainframe computers; such as the DEC VAX and Data General Eclipse, and for equipment such as machine tool numerical controls, printers and video display terminals. As microprocessors became more functional, TTL devices became important for "glue logic" applications, such as fast bus drivers on a motherboard, which tie together the function blocks realized in VLSI elements.

Analog applications.

While originally designed to handle logic-level digital signals, a TTL inverter can be biased as an analog amplifier. Connecting a resistor between the output and the input biases the TTL element as a negative feedback amplifier. Such amplifiers may be useful to convert analog signals to the digital domain but would not ordinarily be used where analog amplification is the primary purpose. TTL inverters can also be used in crystal oscillators where their analog amplification ability is significant.  A TTL gate may operate inadvertently as an analog amplifier if the input is connected to a slowly changing input signal that traverses the unspecified region from 0.8 V to 2 V. The output can be erratic when the input is in this range. A slowly changing input like this can also cause excess power dissipation in the output circuit. If such an analog input must be used, there are specialized TTL parts with Schmitt trigger inputs available that will reliably convert the analog input to a digital value, effectively operating as a one bit A to D converter.

Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function (the first "transistor") and the amplifying function (the second "transistor"); it is the same naming convention used in resistor–transistor logic (RTL) and diode–transistor logic (DTL).

Transistor-Transistor Logic ou TTL est une famille de circuits logiques utilisée en électronique inventée dans les années 1960. Cette famille est réalisée avec la technologie du transistor bipolaire et tend à disparaître du fait de sa consommation énergétique élevée (comparativement aux circuits CMOS).


Early life.

Gephardt was born in St. Louis, Missouri, the son of Loreen Estelle (née Cassell) and Louis Andrew Gephardt, a Teamster milkman; part of his ancestry is German. He graduated from the former Southwest High School in 1958. Gephardt is an Eagle Scout and recipient of the Distinguished Eagle Scout Award from the Boy Scouts of America. He earned his B.S. at Northwestern University in 1962 where he was president of Beta Theta Pi, the student senate, and his freshman class. He earned his J.D. at the University of Michigan Law School in 1965.  In 1965, he was admitted to the Missouri Bar. He then entered the Missouri Air National Guard, where he served until 1971.  He and his wife Jane have three grown children, Matt, Katie, and Chrissy. His brother, Donald L. Gephardt, was the Dean of The College of Fine and Performing Arts at Rowan University in Glassboro, New Jersey.

Political career.

Gephardt was Democratic committeeman for the 14th ward in St. Louis from 1968 to 1971, moving up to become 14th ward alderman from 1971 to 1976, as part of a group of young aldermen known informally as "The Young Turks."

House of Representatives.

In 1976, Gephardt was elected to Congress from the St. Louis-based 3rd District, succeeding 24-year incumbent Leonor Sullivan. He was elected 13 more times, opting not to run for reelection in 2004. For most of his Congressional career, Gephardt's National Political Director was St. Louis-based political consultant Joyce Aboussie. Gephardt voted in favor of the bill establishing Martin Luther King Jr. Day as a federal holiday in August 1983 but did not vote on the Civil Rights Restoration Act of 1987 (or the vote to override President Reagan's veto in March 1988).

1988 presidential campaign.

Gephardt was an unsuccessful candidate for the Democratic nomination in the 1988 presidential election. Gephardt formally announced his candidacy in February 1987—one of the first to do so—and campaigned hard in Iowa, ultimately spending over 100 days in the state. He was stuck in low double digits in polls, but began moving ahead in Iowa in late December 1987 after running an ad that criticized trade barriers by Korea and Japan as unfair- known as the "Hyundai Ad." Gephardt won the Iowa caucuses and South Dakota primary in February while finishing a strong second in New Hampshire, making him a serious contender for the nomination.  Gephardt's early victories did not translate into support in other states, though, and he was not able to raise adequate funds to compete in the Southern primaries. His campaign ran out of money after losing badly in the March "Super Tuesday" primaries, when he won only the Missouri primary. An ad aired by Governor Michael Dukakis's campaign focused on Gephardt's "flip-flopping" voting record and showed a Gephardt look-alike doing forward and backward flips for the camera. Many felt the ad killed any chance Gephardt had of winning the nomination. Gephardt dropped out after winning only 13% in Michigan, despite support from the United Auto Workers. Dukakis considered selecting Gephardt as his vice presidential running mate but instead chose Texas Senator Lloyd Bentsen.

House leadership.

In part due to the visibility gained from his 1988 presidential bid, Gephardt was elected majority leader by his House colleagues in June 1989, making him the second-ranking Democrat in the House, behind then-Speaker Tom Foley. Gephardt served in that position until January 1995.  After Foley was unseated in the Republican landslide of 1994 that gave the Republicans a 52-seat majority, Gephardt became the leader of the House Democrats, as minority leader, initially opposite Newt Gingrich and then, from 1999 onward, Dennis Hastert. When Gingrich faced a coup within his own party in 1997, Gephardt could have become Speaker if there had been a floor vote and he gained the support of Republican members dissatisfied with Gingrich, but Gingrich refused to resign and no vote occurred. In the 1996, 1998, and 2000 elections, Gephardt led the Democrats to gains in the House, although they did not retake the majority until 2006, after Gephardt had left Congress.  Gephardt became a prolific financial supporter of Democrats around the country in the early 1990s, assembling a team of top fundraising staff who helped him support hundreds of candidates for local and federal office. Although Gephardt worked hard for many of President Bill Clinton's programs, he and his union supporters strongly opposed NAFTA and other "free trade" programs, so Clinton relied on Republican support to pass those initiatives. During the impeachment proceedings of President Clinton, Gephardt led a walkout in the House after a censure motion was ruled irrelevant to the impeachment debate. In 2000, Vice President and Democratic presidential nominee Al Gore named Gephardt to his short list of possible vice presidential candidates. The other names on the short list were Indiana Senator Evan Bayh, North Carolina Senator John Edwards, Massachusetts Senator John Kerry, Connecticut Senator Joe Lieberman, and New Hampshire Governor Jeanne Shaheen. Gore eventually selected Lieberman.  In the 2002 Congressional midterm elections, Gephardt campaigned on the economy and Social Security, but the continuing resonance of the September 11 attacks, the momentum for military action against Iraq, and President George W. Bush's popularity lead to Republican gains, with the Democrats losing four House seats. Harold Ford of Tennessee called the results an "absolute blowout" and called upon Gephardt to step down, saying that it was time for "new ideas and new faces". Due to his previous success, it has been said that Gephardt would have been easily returned as Minority Leader if he had decided to stay on. However, Gephardt, who was planning to run for president in 2004, did not run for reelection as House Minority Leader, stepping down in January 2003. His leadership position was contested by the centrist Martin Frost, the outgoing Democratic Caucus Chair, and the liberal Nancy Pelosi, the Minority Whip, who was elected as Gephardt's successor. No longer having Congressional leadership duties freed Gephardt up to concentrate on a 2004 presidential bid.

2004 campaign for president.

Gephardt announced his second run for president on January 5, 2003. His successor as Minority Leader, Nancy Pelosi, endorsed him. His campaign was notable for the high-profile coming out of his daughter Chrissy in "People" magazine, while she was helping him on the campaign trail, a subject they also discussed in interviews for the 2007 documentary film "For the Bible Tells Me So"; he has continued to be an outspoken advocate for gay rights since the campaign.  Although Republicans considered him a formidable candidate, Gephardt was seen by many as too old-fashioned and unelectable. His fundraising efforts were behind those of former Vermont Governor Howard Dean and Senators John Kerry and John Edwards, and tied with Joe Lieberman. Gephardt's support of the Iraq War resolution hurt him among liberal activists. He promoted a form of universal health care, and was backed by 21 labor unions, but did not have enough support to receive the AFL-CIO's endorsement. Throughout early 2003, Gephardt was ahead in polling for the Iowa caucus, but by August Dean had taken the lead, his campaign fueled by antiwar activists. The Gephardt campaign was embarrassed by an early August "St Louis Post-Dispatch" article that revealed that 11 of the 33 "Gephardt team leaders" listed on his Iowa campaign's website actually supported other candidates or were neutral.  The race between Gephardt and Dean became negative, and took an ugly turn in October when a Gephardt staffer reportedly pushed a Dean staffer out of a meeting while calling him a "faggot". Many press at the event claimed the Dean staffer was picking a fight and that the Gephardt staffer did not make the hurtful comment. Dean chairman Joe Trippi (who worked for Gephardt in 1988) and Gephardt chairman Steve Murphy became involved in a war of words over the incident, as well as Murphy's allegation that the Dean campaign was bringing in out-of-state non-residents to participate in the caucus. In the final days of the Iowa campaign, both Dean and Gephardt faded, and they finished third and fourth, respectively. Gephardt ended his presidential campaign after that disappointing result.  After he dropped out of the presidential race, Gephardt was mentioned as a possible running mate for John Kerry. On March 7, 2004, New Mexico Governor Bill Richardson, also seen as a strong contender for the position, endorsed Gephardt for Vice President. "I think he's the best candidate," Richardson said of Gephardt in an interview with the Associated Press. "There's a good regional balance with Kerry and Gephardt." Kerry announced on July 6, 2004, that he had chosen John Edwards as his running mate. On the same day, the "New York Post" published a headline stating that Gephardt had become Kerry's running mate. The headline was compared to the 1948 "Dewey defeats Truman" headline in the "Chicago Tribune" that incorrectly reported the presidential election results that year. In 2007, it was revealed in Kerry campaign adviser Bob Shrum's book "No Excuses: Concessions of a Serial Campaigner" that Kerry wanted to choose Gephardt but was convinced by Shrum and others to choose Edwards.

Political views.

After his election to the U.S. House in 1976, Gephardt's political views gradually moved to the left. Originally, Gephardt was strongly anti-abortion and was viewed as a social conservative. He was initially extremely critical of the Supreme Court's landmark "Roe v. Wade" ruling that legalized abortion. He wrote on the subject in 1984: In 1987, when Gephardt decided to run for president, he announced that he would no longer support legislation to restrict abortion rights. He told the National Right to Life Committee; "I now do not support any Constitutional amendment pertaining to the legality of abortion."  Gephardt's views on economic policy also changed over the years. He voted for Ronald Reagan's tax cuts in 1981; in the 2000s, however, he became a staunch opponent of similar tax cuts by President George W. Bush, saying that the enormous surplus created during the administration of Bill Clinton should have been spent on health care instead. Gephardt is widely viewed as an economic populist. He supports universal health coverage, fair trade, and progressive taxation. Although he once chaired the centrist Democratic Leadership Council, Gephardt in his later years in Congress distanced himself from the organization, finding his pro-labor views at odds with the DLC's pro-business positions.  On October 10, 2002, Gephardt was among the 81 House Democrats who voted in favor of authorizing the invasion of Iraq. He was an early supporter of the war, and cosponsor of the authorization resolution. However, three years later Gephardt said of his support for the war that "It was a mistake... I was wrong."

Post-congressional career.

On January 3, 2005, Gephardt's three-decade political career ended with the expiration of his 14th term in the House of Representatives. That month, Gephardt started a consulting and lobbying firm, Gephardt Group, of which he is president and CEO. Gephardt also joined the international law firm DLA Piper as strategic advisor in the government affairs practice group from June 2005 to December 2009.  In his new role as a Washington lobbyist, Gephardt, on behalf of the Republic of Turkey, has been actively lobbying against the House resolution condemning the Armenian genocide of 1915 in the Ottoman Empire. While supportive of the resolution while in Congress, he now contends that facts need to be better known before any position is taken on this historical controversy.  Gephardt served on the board of directors of the Embarq Corporation from June 2007 to July 1, 2009, when he became a member of the board of directors of CenturyLink, Embarq's successor corporation. Gephardt also serves as a director of Centene Corporation, Ford Motor Company, Spirit Aerosystems Holdings, Inc., and United States Steel Corporation. He joined Ford's board in 2009.  In July 2007, Gephardt endorsed Hillary Clinton for president, leading some to speculate that he was interested in running for vice president in 2008. DLA Piper become a major donor to Clinton's campaign, donating about $190,000. Gephardt was mentioned during the summer of 2008 as a possible vice-presidential choice for eventual nominee Senator Barack Obama.  A collection of Gephardt's congressional documents, dating from 1994 to 2004, was processed from 2006 to 2007 by the Missouri Historical Society for academic use, with a grant through the Institute of Museum and Library Services. In 2005, Washington University in St. Louis inaugurated the Richard A. Gephardt Institute of Public Service, which promotes volunteerism and community activism. Since 2005, Gephardt has been a consultant to Goldman Sachs and DLA Piper. Since 2007 he has been a consultant to FTI Consulting.  In 2007, Gephardt began serving on the advisory board of the Extend Health insurance company, and then became a member of its board of directors. In 2009, Gephardt advised UnitedHealth Group, one of America's largest private insurers, in waging a strong campaign against a public option for national health care.  In 2010, Gephardt was elected chair of the Board of Trustees of The Scripps Research Institute, a nonprofit institute focusing on biomedical research.  Gephardt has also been significantly involved with the pharmaceutical industry. In addition to a large lobbying contract with the Medicines Company, he serves as chair of the Council for American Medical Innovation (CAMI), formed by and affiliated with PhRMA. In this capacity he hired his own firm to lobby for the organization, to push to extend patents and block generic drugs from the market.  Gephardt has also served as a lobbyist for Boeing. He is a labor consultant for Spirit Aerosystems and sits on its board of directors. In these roles, Gephardt has presided over an aggressive anti-union campaign that has bewildered many of his traditional political allies. In July 2011, Spirit Aerosystems walked out of negotiations with the union that represents its engineering, technical and professional workforce. The union subsequently voted down the company's last contract offer, with 96.5% voting no. The company did not change its contract offer significantly after this rejection and relations with its workforce have been contentious ever since. With negotiations at a standstill, production schedules for 2011 and 2012 were threatened.

Richard Andrew Gephardt (born January 31, 1941) is an American politician who served as a United States Representative from Missouri from 1977 to 2005. A member of the Democratic Party, he was House Majority Leader from 1989 to 1995 and Minority Leader from 1995 to 2003. He ran unsuccessfully for the Democratic nomination for President of the United States in 1988 and 2004. Gephardt was mentioned as a possible vice presidential nominee in 1988, 1992, 2000, 2004, and 2008.

Richard Andrew Gephardt, né le à Saint-Louis (Missouri), est un homme politique américain, membre du Parti démocrate et représentant du 3 district du Missouri à la Chambre des représentants des États-Unis de 1977 à 2005. Il est par ailleurs chef des démocrates à la Chambre entre 1989 et 2003, et à ce titre chef de la majorité entre 1989 et 1995 et de la minorité entre 1995 et 2003.


Process of open market operations.

The central bank maintains loro accounts for a group of commercial banks, the so-called direct payment banks. A balance on such a loro account (it is a nostro account in the view of the commercial bank) represents central bank money in the regarded currency. Since central bank money currently exists mainly in the form of electronic records (electronic money) rather than in the form of paper or coins (physical money), open market operations can be conducted by simply increasing or decreasing ("crediting" or "debiting") the amount of electronic money that a bank has in its reserve account at the central bank. This does not require the creation of new physical currency, unless a direct payment bank demands to exchange a part of its electronic money against banknotes or coins.  In most developed countries, central banks are not allowed to give loans without requiring suitable assets as collateral. Therefore, most central banks describe which assets are eligible for open market transactions. Technically, the central bank makes the loan and synchronously takes an equivalent amount of an eligible asset supplied by the borrowing commercial bank.

Theoretical relationship to interest rates.

Classical economic theory postulates a distinctive relationship between the supply of central bank money and short-term interest rates: like for a commodity, a higher demand for central bank money would increase its price, the interest rate. When there is an increased demand for base money, the central bank must act if it wishes to maintain the short-term interest rate. It does this by increasing the supply of base money: it goes to the open market to buy a financial asset, such as government bonds. To pay for these assets, new central bank money is generated in the seller's loro account, increasing the total amount of base money in the economy. Conversely, if the central bank sells these assets in the open market, the base money is reduced.  Technically, the process works because the central bank has the authority to bring money in and out of existence. It is the only point in the whole system with the unlimited ability to produce money. Another organization may be able to influence the open market for a period of time, but the central bank will always be able to overpower their influence with an infinite supply of money.  Side note: Countries that have a free floating currency not pegged to any commodity or other currency have a similar capacity to produce an unlimited amount of net financial assets (bonds). Understandably, governments would like to utilize this capacity to meet other political ends like unemployment rate targeting, or relative size of various public services (military, education, health etc.), rather than any specific interest rate. Mostly, however the central bank is prevented by law or convention from giving way to such demands, being required to only generate central bank money in exchange for eligible assets (see above).

How open market operations are conducted.

United States.

In the United States, as of 2006, the Federal Reserve sets an interest rate target for the federal funds ("overnight bank reserves") market. When the actual federal funds rate is higher than the target, the Federal Reserve Bank of New York will usually increase the money supply via a repurchase agreement (or repo), in which the Fed "lends" money to commercial banks. When the actual federal funds rate is less than the target, the Fed will usually decrease the money supply via a reverse repo, in which the banks purchase securities from the Fed. The Federal Reserve conducts open market operations with the objective of controlling short-term interest rates and the money supply. These operations fall into 2 categories: Dynamic open market operations are intended to change the level of reserves and the monetary base, and defensive open market operations are intended to offset movements in other factors that affect reserves and the monetary base, such as changes in Treasury deposits with the Fed or changes in float. In the United States, the Federal Reserve most commonly uses overnight repurchase agreements (repos) to temporarily create money, or reverse repos to temporarily destroy money, which offset temporary changes in the level of bank reserves. The Federal Reserve also makes outright purchases and sales of securities through the System Open Market Account (SOMA) with its manager over the Trading Desk at the New York Reserve Bank. The trade of securities in the SOMA changes the balance of bank reserves, which also affects short-term interest rates. The SOMA manager is responsible for trades that result in a short-term interest rate near the target rate set by the Federal Open Market Committee ("FOMC"), or create money by the outright purchase of securities. More rarely will it permanently destroy money by the outright sale of securities. These trades are made with a group of about 22 banks and bond dealers called primary dealers.  Money is created or destroyed by changing the reserve account of the bank with the Federal Reserve. The Federal Reserve has conducted open market operations in this manner since the 1920s, through the Open Market Desk at the Federal Reserve Bank of New York, under the direction of the Federal Open Market Committee. OMOs also control inflation because when treasury bills are sold to commercial banks, it decreases the money supply.

Eurozone.

The European Central Bank has similar mechanisms for their operations; it describes its methods as a four-tiered approach with different goals: beside its main goal of steering and smoothing Eurozone interest rates while managing the liquidity situation in the market the ECB also has the aim of signalling the stance of monetary policy with its operations.  Broadly speaking, the ECB controls liquidity in the banking system via refinancing operations, which are basically repurchase agreements, i.e. banks put up acceptable collateral with the ECB and receive a cash loan in return. These are the following main categories of refinancing operations that can be employed depending on the desired outcome:  Refinancing operations are conducted via an auction mechanism. The ECB specifies the amount of liquidity it wishes to auction (called the allotted amount) and asks banks for expressions of interest. In a fixed rate tender the ECB also specifies the interest rate at which it is willing to lend money; alternatively, in a variable rate tender the interest rate is not specified and banks bid against each other (subject to a minimum bid rate specified by the ECB) to access the available liquidity.  MRO auctions are held on Mondays, with settlement (i.e., disbursal of the funds) occurring the following Wednesday. For example, at its auction on 6 October 2008, the ECB made available 250 million in EUR on 8 October at a minimum rate of 4.25%. It received 271 million in bids, and the allotted amount (250) was awarded at an average weighted rate of 4.99%.  Since mid-October 2008, however, the ECB has been following a different procedure on a temporary basis, the fixed rate MRO with "full allotment". In this case the ECB specifies the rate but not the amount of credit made available, and banks can request as much as they wish (subject as always to being able to provide sufficient collateral). This procedure was made necessary by the financial crisis of 2008 and is expected to end at some time in the future.  Though the ECB's main refinancing operations ("MRO") are from repo auctions with a (bi)weekly maturity and monthly maturation, Longer-Term Refinancing Operations (LTROs) are also issued, which traditionally mature after three months; since 2008, tenders are now offered for six months, 12 months and 36 months.

Switzerland.

The Swiss National Bank (SNB) currently targets the three-month Swiss franc LIBOR rate. The primary way the SNB influences the three-month Swiss franc LIBOR rate is through open market operations, with the most important monetary policy instrument being repo transactions.

India.

India's Open Market Operation is much influenced by the fact that it is a developing country and that the capital flows are very different from those in developed countries. Thus India's central bank, the Reserve Bank of India (RBI), has to make policies and use instruments accordingly. Prior to the 1991 financial reforms, RBI's major source of funding and control over credit and interest rates was the cash reserve ratio (CRR) and the SLR (Statutory Liquidity Ratio). But after the reforms, the use of CRR as an effective tool was deemphasized and the use of open market operations increased. OMOs are more effective in adjusting [market liquidity].  The two type of OMOs used by RBI:  However, even after sidelining CRR as an instrument, there was still less liquidity and skewedness in the market. And thus, on the recommendations of the Narsimham Committee Report (1998), The RBI brought together a Liquidity Adjustment Facility (LAF). It commenced in June, 2000, and it was set up to oversee liquidity on a daily basis and to monitor market interest rates. For the LAF, two rates are set by the RBI: repo rate and reverse repo rate. The repo rate is applicable while selling securities to RBI (daily injection of liquidity), while the reverse repo rate is applicable when banks buy back those securities (daily absorption of liquidity). Also, these interest rates fixed by the RBI also help in determining other market interest rates.  India experiences large capital inflows every day, and even though the OMO and the LAF policies were able to withhold the inflows, another instrument was needed to keep the liquidity intact. Thus, on the recommendations of the Working Group of RBI on instruments of sterilization (December, 2003), a new scheme known as the market stabilization scheme (MSS) was set up. The LAF and the OMO's were dealing with day-to-day liquidity management, whereas the MSS was set up to sterilize the liquidity absorption and make it more enduring.  According to this scheme, the RBI issues additional T-bills and securities to absorb the liquidity. And the money goes into the Market Stabilization scheme Account ("MSSA"). The RBI cannot use this account for paying any interest or discounts and cannot credit any premiums to this account. The government, in collaboration with the RBI, fixes a ceiling amount on the issue of these instruments.

An open market operation (OMO) is an activity by a central bank to give (or take) liquidity in its currency to (or from) a bank or a group of banks. The central bank can either buy or sell government bonds in the open market (this is where the name was historically derived from) or, in what is now mostly the preferred solution, enter into a repo or secured lending transaction with a commercial bank: the central bank gives the money as a deposit for a defined period and synchronously takes an eligible asset as collateral. A central bank uses OMO as the primary means of implementing monetary policy. The usual aim of open market operations is—aside from supplying commercial banks with liquidity and sometimes taking surplus liquidity from commercial banks—to manipulate the short-term interest rate and the supply of base money in an economy, and thus indirectly control the total money supply, in effect expanding money or contracting the money supply. This involves meeting the demand of base money at the target interest rate by buying and selling government securities, or other financial instruments. Monetary targets, such as inflation, interest rates, or exchange rates, are used to guide this implementation.

Background and preparations.

Three nations bid for host duties: United States, Brazil, and Morocco. The vote was held in Zurich on July 4, 1988, and only took one round with the United States bid receiving a little over half of the votes by the Exco members. FIFA hoped that by staging the world's most prestigious tournament there, it would lead to a growth of interest in the sport. An inspection committee also found that the proposed Brazilian stadiums were deficient, while the Moroccan bid relied on the construction of nine new stadiums. The U.S. bid was seen as the favorite and was prepared in response to losing the right to be the replacement host for the 1986 tournament following Colombia's withdrawal.  One condition FIFA imposed was the creation of a professional football league—Major League Soccer was founded in 1993 and began operating in 1996. There was some initial controversy about awarding the World Cup to a country where football was not a nationally popular sport, and at the time, in 1988, the U.S. did not have a professional league of its own anymore; the North American Soccer League, set up in the 1970s, had folded in 1984 after attendance faded. The success of the 1984 Summer Olympics, particularly the soccer tournament, also contributed to FIFA's decision.

Mascot.

The official mascot of this World Cup was "Striker, the World Cup Pup", a dog wearing a red, white and blue soccer uniform with a ball. Striker was designed by the Warner Bros. animation team. A dog was picked as the mascot because dogs are a common pet in the United States.

Sponsorship.

The sponsors of the 1994 FIFA World Cup are divided into two categories: FIFA World Cup Sponsors and USA Supporters.  The official game ball was the Adidas Questra.

Venues.

The games were played in nine cities across the United States. All stadiums had a capacity of at least 53,000, and their usual tenants were professional or college American football teams. Other considered venues in Atlanta, Denver, Kansas City, Las Vegas, Miami, Minneapolis, New Orleans, Philadelphia, Seattle and Tampa were not used, as well as venues in smaller towns such as Annapolis, Maryland; Columbus, Ohio; Corvallis, Oregon; and New Haven, Connecticut. Several modern venues, including Joe Robbie Stadium in Miami and Candlestick Park in San Francisco were rejected because of conflicts with Major League Baseball, so Stanford Stadium, another venue in the Bay Area southeast of San Francisco was used, and the Citrus Bowl, a venue in Orlando was picked over Miami's two submitted venues, much to the world media's surprise (the other Miami venue was the Orange Bowl). The venue used most was the Rose Bowl in Pasadena, with eight games, among them one round of 16 match, a semi-final, the third-place game, and the final. Giants Stadium near New York hosted seven matches including a semi-final; Boston (Foxborough), San Francisco (Stanford) and Dallas hosted six matches each and Chicago, Washington and Orlando each hosted five matches. The least used was the Pontiac Silverdome near Detroit, the first indoor stadium used in a World Cup, with four group stage games. The Pontiac Silverdome was also the only venue of the nine used that did not host any knockout round matches.  Because of the large area of the continental United States, the match locations were often far apart. Some teams in Groups A and B had to travel from Los Angeles or San Francisco all the way to Detroit and back again, covering and three time zones one way. The teams in Groups C and D only played in Foxborough (Boston), Chicago and Dallas – a trip from Boston to Dallas is, but only covers two time zones; Chicago is in the same time zone as Dallas but is still away from both Dallas and Boston. The teams in Groups E and F had it a bit easier – they played exclusively in East Rutherford (New York City), Washington and Orlando, which while far apart are at least all in the same time zone. A few teams, such as Cameroon and Italy, did not have to travel great distances to cities to play matches.  The variety of climate in different cities all over the United States also made playing conditions challenging. Aside from the oceanic coolness of Boston (Foxborough), the Mediterranean climate of San Francisco (Stanford) and occasionally the coolness of Chicago, as they had been in Mexico in 1970 and 1986 most matches were played in hot and/or humid conditions, thanks to nearly all of the matches being scheduled to be played during the day instead of at night in order to suit a time difference compromise for television in Europe, Africa, and the Middle East; this had always been done every time a World Cup was held in the Americas. Although playing in the mostly dry heat and smoggy conditions of Los Angeles (Pasadena) and the mixture of heat and humidity of Washington and New York City (East Rutherford) proved to be difficult, the cities with the most oppressive conditions were the southern cities of Orlando and Dallas because of the combination of heat and extreme humidity. The Floridian tropical climate of Orlando meant all matches there were played in temperatures of or above with humidity at 70% or more (the temperature there during the group stage match between Mexico and Ireland was ) thanks to the mid-day start times. Dallas was not much different: in the semi-arid heat of a Texas summer, temperatures exceeded during mid-day, when matches there were staged in the open-type Cotton Bowl meant that conditions were just as oppressive there as they were in Orlando. Detroit also proved to be difficult: the Pontiac Silverdome did not have a working cooling system and because it was an interior dome-shaped stadium, the air could not escape through circulation, so temperatures inside the stadium would climb past with 40% humidity. United States midfielder Thomas Dooley described the Silverdome as "the worst place I have ever played at".

Participating teams and officials.

Qualification.

Three teams, one African, one Asian, and one European, made their debuts at the 1994 tournament. Nigeria qualified from the African zone alongside Cameroon and Morocco as CAF was granted three spots as a result of the strong performances by African teams in 1990. In the Asian zone, Saudi Arabia qualified for the first time by topping the final round group ahead of South Korea as both edged out Japan, who were close to making their own World Cup debut, but were denied by Iraq in what became known as the "Agony of Doha". The Japanese would not have to wait long though, debuting in the 1998 tournament. In the European zone, Greece made their first World Cup appearance after topping a group from which Russia also qualified, competing independently for the first time after the dissolution of the Soviet Union.  The defending champions West Germany were united with their East German counterparts, representing the unified Germany for the first time since the 1938 World Cup. Norway qualified for the first time since 1938, Bolivia for the first time since 1950, and Switzerland for the first time since 1966. Norway's 56-year gap between appearances in the final tournament equaled Egypt's record in the previous tournament as the longest. Mexico had its first successful qualification campaign since 1978, failing to qualify in 1982, qualifying as hosts in 1986 and being banned for the Cachirules scandal in 1990.  The qualification campaigns of both Czechoslovakia and Yugoslavia were affected by political events. The nation of Czechoslovakia dissolved in 1993, completing its qualifying group under the name "Representation of Czechs and Slovaks" (RCS), but failed to qualify for the finals, having been edged out by Romania and Belgium in Group 4. Yugoslavia (which was supposed to play in Group 5) was suspended from international competition in 1992 as part of United Nations sanctions against the country as a result of the Yugoslav Wars. The sanctions were not lifted until 1994, by which time it was no longer possible for the team to qualify. Chile's suspension from the 1990 FIFA World Cup, following the forced interruption of their qualification game against Brazil, extended to the 1994 qualifiers as well.  This was the first World Cup since World War II in which none of the Home Nations of England, Scotland, Northern Ireland and Wales qualified (they withdrew their FIFA memberships between 1928–1946, during the first three tournaments), with England (finishing third behind Norway and Netherlands in Group 2) missing out after having finished fourth in the 1990 tournament, and Scotland (who finished fourth in Group 1) failing to qualify for the first time since 1970. France, who had been already designated as hosts of the 1998 tournament, also missed out following surprise home losses to Israel and Bulgaria. This was the second World Cup in a row for which France had failed to qualify, and the last one to date to not feature England, France, and Japan. Other notable absentees were 1990 Round of 16 participants Uruguay, UEFA Euro 1992 champions Denmark, Poland, Portugal and Hungary.

List of qualified teams.

The following 24 teams, shown with final pre-tournament rankings, qualified for the final tournamentː

Squads.

Teams were selected following usual FIFA rules with 22 players. Greece, Italy, Saudi Arabia, and Spain were the only countries that had all their players coming from domestic teams, while the Republic of Ireland and Nigeria had no players from domestic teams. Saudi Arabia was the only team with no players from European teams.

Seeding and draw.

The composition of the four pots was based on the FIFA World Ranking (established in 1993) and on the qualified teams' results in the three previous World Cups. The teams' pre-tournament rankings are shown in parenthesis. The principle of the draw was that each group must have at least two European teams, USA and Mexico could not be drawn in the same group, and Brazil and Argentina could not be drawn with another South American team.  The draw for the tournament took place at the Las Vegas Convention Center on December 19, 1993, officiated by general-secretary Sepp Blatter. Teams were drawn by German legend Franz Beckenbauer, heavyweight boxing champion Evander Holyfield and comedian and actor Robin Williams. Numbers for placement in the group were drawn by actor Beau Bridges, Women's World Cup champion Michelle Akers, model Carol Alt, artist Peter Max, racecar driver Mario Andretti and Olympic gold medalist in gymnastics Mary Lou Retton.

Summary.

Despite the controversy, the U.S. staged a hugely successful tournament, with an average attendance of nearly 70,000 breaking a record that surpassed the 1966 FIFA World Cup average attendance of 51,000, thanks to the large seating capacities the stadiums in the United States provided for the spectators in comparison to the smaller venues of Europe and Latin America. To this day, the total attendance for the final tournament of nearly 3.6 million remains the highest in World Cup history, despite the expansion of the competition from 24 to 32 teams at the 1998 World Cup in France. Germany, Brazil, Argentina, Belgium, Italy, and the United States were seeded for the final draw, which took place in Las Vegas on December 19, 1993.  The format of the competition stayed the same as in the 1990 World Cup: 24 teams qualified, divided into six groups of four. Sixteen teams would qualify for the knockout phase: the six group winners, the six group runners-up, and the four third-placed teams with the best records. This was the last time this format was used, due to the expansion of the finals tournament in 1998 to 32 teams. This World Cup was the first in which three points were awarded for a win instead of two. FIFA instituted this feature to encourage attacking soccer after the defensive display of many teams at Italia '90.  The tournament saw the end of Diego Maradona's World Cup career, having played in the 1982, 1986, and 1990 World Cups, and leading Argentina to the 1986 World Cup title and the final of the 1990 World Cup. Maradona was expelled from the tournament after he failed a drug test which uncovered ephedrine, a weight-loss drug, in his blood. Colombia, despite high expectations due to their style and impressive qualifying campaign, failed to advance from the round robin. The team was supposedly dogged by influence from betting syndicates and drug cartels, with coach Francisco Maturana receiving death threats over squad selection. Defender Andrés Escobar was a tragic figure of this tournament, as in the group stage game against the United States, he scored an own goal that eliminated his team. Escobar was shot to death outside a bar in a Medellín suburb only 10 days later, apparently in retaliation for the own goal. On the field, Bulgaria was one of the biggest surprises of the tournament. The Bulgarians had never won a game in five previous World Cup finals but, led by Hristo Stoichkov who eventually shared the tournament lead in scoring, they made a surprising run; Bulgaria won two of their three group games to qualify for the second round, where they advanced with a 3–1 penalty shoot-out win over Mexico. Bulgaria then faced the reigning world champions, Germany, in the quarter-finals, where goals from Stoichkov and Yordan Letchkov gave them a 2–1 victory. Bulgaria went on to finish in fourth place after losing to Italy and Sweden, in the semi-finals and third-place game, respectively.  The United States, relatively new to professional football, advanced to the second round as one of the best third-place teams. They played Brazil on Independence Day and, despite a 1–0 defeat, the United States' performance was considered a great success in their football history.  Brazil's win over the hosts helped take them to the final against Italy. Brazil's path was relatively smooth though not easy, as they defeated the Netherlands in the quarter-finals and Sweden in the semis. The Italians meanwhile had made hard work of reaching the final. During the group stage, Italy struggled and narrowly advanced to the next round, despite losing 1–0 to the Republic of Ireland. Italian playmaker Roberto Baggio, who as the reigning FIFA World Player of the Year and Ballon D'Or holder, was expected to be one of the stars of the tournament, had not yet scored a goal. During the Round of 16 games against Nigeria, Italy was trailing 1–0 in the dying minutes when Baggio scored the tying goal, forcing the game into extra time. He scored again with a penalty kick to send Italy through. Baggio carried the Italians from there, scoring the game-winning goal in the quarter-final against Spain, and both goals in Italy's semi-final victory over Bulgaria.  The third-place playoff was set between Bulgaria and Sweden, the team which scored more goals than any other in this World Cup. These teams had also previously met in the qualifying group. Sweden won, 4–0. Swedish forward Tomas Brolin was named to the All-star team.  The final game at the Rose Bowl was tense but devoid of scoring chances. It was the second time in 24 years that the two nations had met in a final. Despite the strategies implemented by FIFA to promote offensive play, both teams failed to produce a goal. After 120 goalless minutes, the World Cup was decided for the first time by a penalty shoot-out. After four rounds, Brazil led 3–2, and Baggio, playing injured, had to score to keep Italy's hopes alive. He missed by shooting it over the crossbar, and the Brazilians were crowned champions for the fourth time. After the game ended, then-Vice-President Al Gore hosted the awarding ceremony by handing Brazilian captain Dunga the prestigious trophy; the Brazilian national team dedicated the title to the deceased Formula One motor racing champion and countryman Ayrton Senna, who had died two and a half months prior.  The tournament's Golden Boot went jointly to Bulgaria's Stoichkov and Oleg Salenko of Russia, the latter becoming the first player to score five goals in a game, coming in a 6–1 victory against Cameroon. Both players scored six goals in the tournament. Brazilian striker Romário, with five goals, won the Golden Ball as the tournament's best player.

Opening ceremony.

The opening ceremony of the World Cup was held on June 17 at Chicago's Soldier Field. The ceremony was emceed by Oprah Winfrey, who fell off the dais in introducing Diana Ross, who gave a musical performance. Ross was also supposed to kick a football into the goal from the penalty spot at the beginning of her performance, with the goal then splitting in two as part of a pre-orchestrated stunt. She kicked the ball wide to the left, missing the goal, but the goalposts were collapsed anyway in accordance with the stunt plans. In addition, Daryl Hall and Jon Secada also gave musical performances.

Group stage.

"Times are Eastern Daylight Time () (East Rutherford, Foxborough, Orlando, Pontiac and Washington), Central Daylight Time () (Chicago and Dallas), and Pacific Daylight Time () (Pasadena and Stanford)." In the following tables:

Group A.

The Group A game between the United States and Switzerland was the first to take place indoors, played under the roof at the Pontiac Silverdome.  Following the tournament, Colombian defender Andrés Escobar was shot dead on his return to Colombia, after his own goal had contributed to his country's elimination.  Victories against Colombia and the United States (in front of a crowd of 93,869) were enough to see Romania through as group winners, despite a 4–1 hammering by Switzerland in between. The magnitude of that victory allowed Switzerland to move ahead of the United States on goal difference, although the hosts qualified for the second round as one of the best third-placed teams.  Switzerland's 4–1 victory over Romania came nearly 40 years to the date of Switzerland's last World Cup victory, also a 4–1 victory, on that occasion over Italy. The United States' 2–1 victory over Colombia was its first World Cup victory since June 29, 1950 when it upset England 1–0 in the 1950 World Cup.

Group B.

Group B produced two of the four semi-finalists of this World Cup, and was also one of the two groups in which two, rather than three, sides would progress to the second round. Brazil and Sweden proved to be far stronger than Cameroon and Russia in every department. The game between the latter two broke two World Cup records. Oleg Salenko of Russia became the first – and remains the only – man to score five goals in a single World Cup game as Russia ran out 6–1 winners against their African opponents. The goals also ensured that Salenko finished the tournament joint-top scorer with six goals, having previously bagged one against Sweden. Cameroon left a mark too as Roger Milla, at the age of 42, became the oldest World Cup goalscorer of all time as he grabbed his side's consolation goal in the game. The result was not enough to take Russia through following heavy defeats at the hands of both Brazil and Sweden. Brazil overcame Cameroon with similar ease before a draw with Sweden confirmed top spot.  The Swedes also progressed, finishing in second place with five points. Sweden's 3–1 victory over Russia was the nation's first World Cup victory, in a knockout stage game, since July 3, 1974. Russia failed to progress to the second round for the second time, while Cameroon failed to repeat their surprise performance from the previous tournament.

Group C.

As was the case with Group B, Group C would only send two teams into the Round of 16 as Spain and defending champions Germany progressed to round two. Coming from two goals down with four minutes left to snatch a 2–2 draw against Spain, the South Koreans very nearly eclipsed that feat against Germany when they came from 3–0 down to lose narrowly 3–2. In spite of these comebacks, South Korea was held to a 0–0 draw against Bolivia in their other group game when a win would have seen them through. Spain's late implosion against the South Koreans effectively decided that it would be Germany who won the group and not them.  Germany, who defeated Bolivia 1–0 in the tournament's opening game, finished with seven points. Spain had to settle for second place despite leading in all three games.  Despite Bolivia finishing last in the group, Erwin Sanchez made team history after scoring the nation's first World Cup goal in a 3–1 loss to Spain. Prior to 1994, Bolivia had never scored in either of their previous appearances at the 1930 and 1950 World Cups.

Group D.

Tournament favorites Argentina led by Diego Maradona collected a maximum of six points from their opening two games after dominating Greece 4–0 in Foxboro with a Gabriel Batistuta hattrick before winning a close match against a formidable Nigeria with a 2–1 victory on the same field four days later; despite this Argentina finished third in the group. Nigeria had been very impressive on their World Cup debut, and despite the narrow loss to Argentina, had emerged as group winners following victories against Bulgaria and Greece, the latter in which Nigeria doubled its lead late on a goal from Daniel Amokachi – a goal that would allow Nigeria to top its group. Maradona only played with Argentina during their first two games, both in Foxborough (playing Greece and Nigeria and scoring his last ever World Cup goal against the former); he was thrown out of the tournament after testing positive for ephedrine.  Having qualified for the tournament through a last-gasp goal against France, Bulgaria surprised many people, as the nation had never even won a game at the World Cup finals prior to this tournament. Despite losing its opening game 3–0 to Nigeria, Bulgaria came back in style with a 4–0 win over Greece (who had suffered exactly the same fate five days earlier against Argentina), and a 2–0 win against Argentina saw them advance. Argentina had actually been winning the group going into injury time, while Bulgaria played the last 25 minutes with 10 men; however, a 91st-minute header from Nasko Sirakov meant that Argentina dropped two places and finished third. Nigeria won the group on goal difference. Bulgaria's victory over Argentina earned them second place.

Group E.

Group E remains the only group in World Cup history in which all four teams finished with the same points and same goal difference. It began at Giants Stadium where Ray Houghton's chip ensured a shock Irish victory over the then-three-time champions Italy by 1–0, as well as gaining a measure of revenge for the previous World Cup, in which Italy both hosted and eliminated Ireland at quarter-finals. The next day in Washington, Norway played its first World Cup game since 1938 and Kjetil Rekdal's goal five minutes from time proved decisive in an equally tense encounter as Norway beat Mexico.  In the second round of group play, the tropical weather of Orlando played a key factor for Mexico in their next game against Ireland. The match was held in record-breaking heat and humidity, temperatures in which the Mexicans were accustomed to but visibly uncomforted the Irish. Luis García's double had them 2–0 up and in control of the game before a disagreement on the touchline resulted in fines for both Republic of Ireland's manager, Jack Charlton, and their striker John Aldridge. Aldridge was able to regain concentration in time to score six minutes from the end of the game to make it 2–1. Despite their loss, Aldridge's goal proved crucial to Ireland in the final group standings.  During the previous day at Giants Stadium in New Jersey, Italy's World Cup hopes seemed to be diminishing fast as goalkeeper Gianluca Pagliuca was sent off with the game still at 0–0. Yet despite this, Italy was still able to salvage an important 1–0 victory. Norway would ultimately pay a price for their inability to take advantage of Pagliuca's dismissal. With the four teams level on points, the final two group games would each have to finish as draws for things to stay that way. Republic of Ireland made it through after a dreary 0–0 draw with Norway; midfielders Massaro and Bernal traded strikes as Italy and Mexico played to a 1–1 draw.  Those results meant that Mexico won the group on goals scored, with three in the group. With Ireland and Italy also progressing having finished with identical records, the Irish team qualified as second place as a result of their victory against the Italians. Norway's shortcomings in attack ultimately let them down, and they exited the tournament with only one goal.

Group F.

Just as happened to Argentina in Group D, Belgium endured the same fate in Group F. Despite winning both of its first two matches 1–0 against Morocco and neighbors Netherlands, Belgium finished third as, in an upset, it lost to tournament newcomers Saudi Arabia 1–0 in the third game. During that game, Saudi player Saaed Al-Owairian ran from his own half through a maze of Belgian players to score the game's only goal.  Saudi Arabia advanced through to the Round of 16 as well, having also defeated Morocco 2–1. The Netherlands endured a somewhat nervier experience. The opening 2–1 victory against Saudi Arabia was followed by the 1–0 loss against Belgium before another 2–1 victory against Morocco, with Bryan Roy scoring the winner a mere 12 minutes from time, saw the Dutch win the group because of having scored more goals against Belgium and Saudi Arabia. Morocco, despite losing all three of their group games, did not leave without a fight, as each of their losses were by just a single goal, 1–0 to Belgium, 2–1 to Saudi Arabia, and 2–1 to the Netherlands.

Statistics.

Goalscorers.

Hristo Stoichkov and Oleg Salenko received the Golden Boot for scoring six goals. In total, 141 goals were scored by 81 players, with only one of them credited as an own goal.

All-star team.

The All-star team is a squad consisting of the eleven most impressive players at the 1994 World Cup, as selected by FIFA's Technical Study Group.

Final standings.

After the tournament, FIFA published a ranking of all teams that competed in the 1994 World Cup finals based on progress in the competition, overall results and quality of the opposition.

The 1994 FIFA World Cup was the 15th FIFA World Cup, the world championship for men's national soccer teams. It was hosted by the United States and took place from June 17 to July 17, 1994, at nine venues across the country. The United States was chosen as the host by FIFA on July 4, 1988. Despite the host nation's lack of soccer tradition, the tournament was the most financially successful in World Cup history; aided by the high-capacity stadiums in the United States, it broke the World Cup average attendance record with more than 69,000 spectators per game, a mark that still stands. The total attendance of nearly 3.6 million for the final tournament remains the highest in World Cup history, despite the later expansion of the competition from 24 to 32 teams (and from 52 to 64 games), which was first introduced at the 1998 World Cup and is the current format.

La Coupe du monde de football de 1994 est organisée pour la première fois aux États-Unis. Du 17 juin au 17 juillet, la FIFA espère ainsi y implanter durablement le "soccer". Dans la foulée, il est d'ailleurs prévu de relancer un championnat professionnel dans le pays : ce sera la Major League Soccer qui aura du succès à ses débuts.


Description.

"Sedum" is a genus that includes annual, biennial, and perennial herbs. They are characterised by succulent leaves and stems. The extent of morphological diversity and homoplasy make it impossible to characterise "Sedum" phenotypicaly.

Taxonomy.

"Sedum" was first formally described by Carl Linnaeus in 1753. Of the genera encompassed by the Crassulaceae family, "Sedum" is the most species rich, the most morphologically diverse and most complex taxonomically. Historically it was placed in the subfamily Sedoideae, of which it was the type genus. Of the three modern subfamilies of the Crassulaceae, based on molecular phylogenetics "Sedum" is placed in the subfamily Sempervivoideae. Although the genus has been greatly reduced, from about 600 to 420–470 species, by forming up to 32 segregate genera, it still constitutes a third of the family and is polyphyletic.  "Sedum" species are found in four of six major crown clades wthin subfamily Sempervivoideae of Crassulaceae and are allocated to tribes, as follows: In addition at least nine other distinct genera appear to be nested within "Sedum". However the number of species found outside of the first two clades (Tribe Sedeae) are only a small fraction of the whole genus. Therefore the current circumscription, which is somewhat artificial and catch-all must be considered unstable. The relationships between the tribes of Sempervivoideae is shown in the cladogram. There are now thought to be approximately 55 European species. "Sedum" demonstrates a wide variation in chromosome numbers, and polyploidy is common. Chromosome number is considered an important taxonomic feature.

Subdivision.

Linnaeus originally described 15 species, characterised by pentamerous flowers, dividing them into two groups; Planifolia and Teretifolia, based on leaf morphology. with 15 species, and hence bears his name as the botanical authority (L.). By 1828, de Candolle recognized 88 species, in six informal groups. Various attempts have been made to subdivide this large genus, in addition to segregating separate genera, including creation of informal groups, sections, series and subgenera. For an extensive history of subfamily Sedoideae, see.  Gray (1821) divided the 13 species known in Britain at that time into five sections; "Rhodiola", "Telephium", "Sedum", (unnamed) and "Aizoon". In 1921 Praeger established ten sections; "Rhodiola", "Pseudorhodiola", "Giraldiina", "Telephium", "Aizoon", "Mexicana", "Seda Genuina", "Sempervivoides", "Epeteium" and "Telmissa". This was later revised in what is the best known system, that of Berger (1930), who defined 22 subdivisions, which he called "Reihe" (sections or series). Berger's sections were:  A number of these, he further subdivided. In contrast, Fröderströmm (1935) adopted a much broader circumscription of the genus, accepting only "Sedum" and "Pseudosedum" within the Sedoideae, dividing the former into 9 sections. Although this was followed by numerous other systems, the most widely accepted infrageneric classification following Berger, was by Ohba (1978). Prior to this most species in Sedoideae were placed in genus "Sedum". Of these systems, it was observed "No really satisfactory basis for the division of the family into genera has yet been proposed".  Some other authors have added other series, and combined some of the series into groups, such as sections. In particular "Sedum" section "Sedum" is divided into series (see Clades) More recently, two subgenera have been recognised, "Gormania" and "Sedum".  Subgenus "Sedum" has been considered as three geographically distinct, but equal sized sections:  "S." sect. "Sedum" includes 54 species native to Europe, which Berger classified into 27 series. Nikulin and colleagues (2016) have recommended that, given the monophyly of Aeonieae and Semperviveae, species of "Sedum" outside of the tribe Sedeae (all in subgenus "Gormania") be removed from the genus and reallocated. However this does not resolve the problem of other genera embedded within "Sedum", in Sedeae.  Species and series include

Subgenus "Gormania".

Of about 80 Eurasian species, series "Rupestria" forms a distinct monophyletic group of about ten taxa, which some authors have considered a separate genus, "Petrosedum". It was series 20 in Berger's classification. Native to Europe it has escaped cultivation and become naturalized in North America.  Embedded within series "Monanthoidea" are three Macaronesian segregate genera, "Aichryson", "Monanthes" and "Aeonium".  Embedded within the Leucosedum clade are the following genera: "Rosularia", "Prometheum", "Sedella" and "Dudleya". "Rosularia" is paraphyletic, and some "Sedum" species, such as "S. sempervivoides" are assigned by some authors to "Rosularia", as "R. sempervivoides".

Subgenus "Sedum".

Embedded within the Acre clade are the following genera: "Villadia", "Lenophyllum", "Graptopetalum", "Thompsonella", "Echeveria" and "Pachyphytum". The species within Acre, can be broadly grouped into two subclades, American/European and Asian.

Distribution and habitat.

Distributed in mainly in temperate to subtropical climates the Northern hemisphere, extending to the Southern hemisphere in Africa and South America, being most diverse in the Mediterranean, Central America, Himalayas, and East Asia. In this respect, the two subgenera differ. Subgenus "Sedum" having a centre of diversity in Mexico, and Gormania in Eurasia with a secondary centre in N America.

Ecology.

"Sedum" species are used as food plants by the larvae of some Lepidoptera species including the grey chi moth. In particular, "Sedum spathulifolium" is the host plant of the endangered San Bruno elfin butterfly of San Mateo County, California. "Sedum lanceolatum" is the host plant of the more common "Parnassius smintheus" found in the Rocky Mountains. As well as "Sedum spathulifolium", many other species of "Sedum" serve the environmental role of host plants for butterflies. For example, the butterfly "Callophrys xami" uses several species of "Sedum", such as "Sedum allantoides", for suitable host plants.

Uses.

Ornamental.

Many sedums are cultivated as ornamental garden plants, due to their interesting and attractive appearance and hardiness. The various species differ in their requirements; some are cold-hardy but do not tolerate heat, some require heat but do not tolerate cold.  Numerous hybrid cultivars have been developed, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:

As food.

The leaves of most stonecrops are edible, excepting "Sedum rubrotinctum," although toxicity has also been reported in some other species.  "Sedum reflexum", known as "prickmadam", "stone orpine", or "crooked yellow stonecrop", is occasionally used as a salad leaf or herb in Europe, including the United Kingdom. It has a slightly astringent sour taste.  "Sedum divergens", known as "spreading stonecrop", was eaten by First Nations people in northwest British Columbia. The plant is used as a salad herb by the Haida and the Nisga'a people. It is common in the Nass Valley of British Columbia.  Biting stonecrop ("Sedum acre") contains high quantities of piperidine alkaloids (namely (+)-sedridine, (−)-sedamine, sedinone and isopelletierine), which give it a sharp, peppery, acrid taste and make it somewhat toxic.

Roofing.

"Sedum" can be used to provide a roof covering in green roofs, where they are preferred to grasses. Examples include Ford's Dearborn, Michigan Truck Plant, which has a living roof with of sedum. The Rolls-Royce Motor Cars plant in Goodwood, England, has a roof complex covered in "Sedum", the largest in the United Kingdom. Nintendo of America's roof is covered in some of Sedum. The Javits Center in New York City is covered with of Sedum.

Sedum is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as "Sedum" are now in the segregate genera "Hylotelephium" and "Rhodiola".

Le genre Sedum appartient à la famille des crassulacées, il est composé de plus de 400 espèces de plantes succulentes que l'on retrouve à travers l'hémisphère nord. Les sédums (ou orpins) peuvent être des plantes de rocaille ou de petits arbustes. Ces plantes stockent de l'eau dans leurs feuilles et donnent des fleurs en étoile à 5 branches (parfois 4 ou 6). Ils ont généralement 2 fois plus d'étamines que de pétales.


Description.

The stems are tall, erect and furrowed, reddish to sometimes purple. The leaves are dark-green on the upper side and whitish and downy underneath, much divided, interruptedly pinnate, having a few large serrate leaflets and small intermediate ones. Terminal leaflets are large, 4–8 cm long, and three- to five-lobed.  Meadowsweet has delicate, graceful, creamy-white flowers clustered close together in irregularly-branched cymes, having a very strong, sweet smell. They flower from early summer to early autumn and are visited by various types of insects, in particular "Musca" flies.  The flowers are small and numerous, they show 5 sepals and 5 petals with 7 to 20 stamens. Meadowsweet leaves are commonly galled by the bright orange-rust fungus "Triphragmium ulmariae", which creates swellings and distortions on the stalk and/or midrib.

Etymology.

Meadowsweet is known by many other names. In Chaucer's "The Knight's Tale" it is known as meadwort and was one of the ingredients in a drink called "save". It was also known as bridewort, because it was strewn in churches for festivals and weddings, and often made into bridal garlands. In Europe, it took its name "queen of the meadow" for the way it can dominate a low-lying, damp meadow.  The name ulmaria means "elmlike", possibly in reference to its individual leaves which resemble those of the elm ("Ulmus"). Like slippery elm bark, the plant contains salicylic acid, which has long been used as a painkiller. However, the generic name, "Filipendula", comes from "filum", meaning "thread" and "pendulus", meaning "hanging". This is said to describe the root tubers that hang characteristically on the genus, on fibrous roots.

Distribution.

Meadowsweet is common throughout the British Isles in damp areas and is dominant in fens and wet woods.  "Juncus subnodulosus"-"Cirsium palustre" fen-meadow and Purple moor grass and rush pastures BAP habitat plant associations of Western Europe consistently include this plant.

Uses.

The whole herb possesses a pleasant taste and flavour, the green parts having a similar aromatic character to the flowers, leading to the use of the plant as a strewing herb, strewn on floors to give the rooms a pleasant aroma, and its use to flavour wine, beer, and many vinegars. The flowers can be added to stewed fruit and jams, giving them a subtle almond flavor. It has many medicinal properties. The whole plant is a traditional remedy for an acidic stomach, and the fresh root is often used in homeopathic preparations. Dried, the flowers are used in potpourri. It is also a frequently used spice in Scandinavian varieties of mead.  Chemical constituents include salicylic acid, flavone glycosides, essential oils, and tannins. In 1897, Felix Hoffmann created a synthetically altered version of salicin, derived from the species, which caused less digestive upset than pure salicylic acid. The new drug, formally acetylsalicylic acid, was named aspirin by Hoffmann's employer Bayer AG after the old botanical name for meadowsweet, "Spiraea ulmaria". This gave rise to the class of drugs known as non-steroidal anti-inflammatory drugs (NSAIDs).  A natural black dye can be obtained from the roots by using a copper mordant.  A tea made from "Filipendula ulmaria" flowers or leaves has been used in traditional Austrian herbal medicine for the treatment of rheumatism, gout, infections, and fever.

Culture.

White-flowered meadowsweet has been found with the cremated remains of three people and at least one animal in a Bronze Age cairn at Fan Foel, Carmarthenshire. Similar finds have also been found inside a beaker from Ashgrove, Fife, and a vessel from North Mains, Strathallan. These could indicate honey-based mead or flavoured ale, or might suggest the plant placed on the grave as a scented flower.  In Welsh mythology, Gwydion and Math created a woman out of oak blossom, broom, and meadowsweet and named her Blodeuwedd ("flower face").  In the 16th century, when it was customary to strew floors with rushes and herbs (both to give warmth underfoot and to overcome smells and infections), it was a favorite of Elizabeth I of England. She desired it above all other herbs in her chambers.

Filipendula ulmaria, commonly known as meadowsweet or mead wort, is a perennial herb in the family Rosaceae that grows in damp meadows. It is native throughout most of Europe and Western Asia (Near east and Middle east). It has been introduced and naturalised in North America.

La Reine-des-prés ("Filipendula ulmaria"), anciennement appelée ulmaire, ou Fausse spirée, est une plante herbacée vivace de la famille des Rosacées, originaire de l'Europe. C'est une plante mellifère.


Technical information.

Processor and RAM.

The A600 shipped with a Motorola 68000 CPU, running at 7.09 MHz (PAL) or 7.16 MHz (NTSC) and 1 MB "chip" RAM with 80-ns access time.  The designers included no capability to upgrade the original CPU as the 68000 is soldered to the motherboard and there is no other connection for upgrade. Despite this, unofficial CPU upgrades include the Motorola 68010, 68020 (at up to 25 MHz), and 68030 (at up to 50 MHz). The processor is upgraded not by replacing the 68000, but rather by fitting a connector over the CPU and commandeering the system bus. However, this approach caused instability problems with some board designs, prompting custom modifications for stable operation. As a result, such CPU expansions were largely unpopular.  RAM can be upgraded to a maximum of 2 MB "chip RAM" using the trap-door expansion slot. An additional 4 MB of "fast RAM" can be added in the PC Card slot using a suitable SRAM card to reach a capacity of 6 MB. However, more "fast RAM" can be added with unofficial memory or CPU upgrades. For example, the A608 board adds up to a maximum of 8 MB additional RAM by connecting over the original 68000. Likewise, CPU upgrades can accommodate up to 64 MB.  Other unofficial community expansions exist, like the FPGA-driven Vampire which adds 128MB Fastmem RAM, HDMI output, SD card for HDD storage and a 64-bit core with full 32-bit compatibility.

Graphics and sound.

The A600 is the last Amiga model to use Commodore's Enhanced Chip Set (ECS), which can address 2 MB of RAM and adds higher resolution display modes. The so-called Super Agnus display chip can drive screen modes varying from 320×200 pixels to 1280×512 pixels. As with the original Amiga chipset, up to 32 colors can be displayed from a 12-bit (4096 color) palette at lower display resolutions. An extra-half-bright mode offers 64 simultaneous colors by allowing each of the 32 colors in the palette to be dimmed to half brightness. Additionally, a 4096-color "HAM" mode can be used at lower resolutions. At higher resolutions, such as 800×600i, only 4 simultaneous colors can be displayed.  Sound was unchanged from the original Amiga design, namely, 4 DMA-driven 8-bit channels, with two channels for the left speaker and two for the right.  The A600 was the first Amiga model with a built-in RF modulator (RCA), which allowed the A600 to be used with a standard CRT television without the need for a Commodore A520 RF Modulator adaptor.

Peripherals and expansion.

The A600 features Amiga-specific connectors including two DB9M ports for joysticks, mice, and light pens, a standard 25-pin RS-232 serial port and a 25-pin Centronics parallel port. As a result, the A600 is compatible with many peripherals available for earlier Amiga models, such as MIDI, sound samplers and video-capture devices.  Expansion capabilities new to the Amiga line were the PCMCIA Type II slot and the internal 44-pin ATA interface both most commonly seen on laptop computers. Both interfaces are controlled by the 'Gayle' custom chip. The A600 has internal housing for one 2.5" internal hard disk drive connecting to the ATA controller.  The A600 is the first of only two Amiga models to feature a PCMCIA Type II interface. This connector allows use of a number of compatible peripherals available for the laptop-computer market, although only 16-bit PCMCIA cards are hardware-compatible; newer 32-bit PC Card (CardBus) peripherals are incompatible. Mechanically, only Type I and Type II cards fit in the slot; thicker Type III cards will not fit (although they may connect if the A600 is removed from its original case). The port is also not fully compliant with the PCMCIA Type II standard as the A600 was developed before the standard was finalized. The PCMCIA implementation on the A600 is almost identical to the one featured on a later Amiga, the 1200. A number of Amiga peripherals were released by third-party developers for this connector including SRAM cards, CD-ROM controllers, SCSI controllers, network cards, sound samplers, and video-capture devices. Although PCMCIA was similar in spirit to Commodore's expansion architecture for its earlier systems, the intended capability for convenient external expansion through this connector was largely unrealized at the time of release because of the prohibitive expense of PCMCIA peripherals for a lower-budget personal computer. Later, a number of compatible laptop-computer peripherals have been made to operate with the A600, including network cards (both wired and wireless), serial modems and CompactFlash adapters.

Operating system.

The A600 shipped with AmigaOS 2.0, consisting of Workbench 2.0 and a Kickstart ROM revision 37.299, 37.300 or 37.350 (Commodore's internal revision numbers). Confusingly, all three ROM revisions were officially designated as version "2.05". Some early A600s shipped with Kickstart 37.299, which had neither support for the internal ATA controller, nor for the PCMCIA interface. Although it is possible to load the necessary drivers from floppy disk, it is not possible to boot directly from ATA or PCMCIA devices. Models fitted with Kickstart 37.300 or 37.350 can utilize those devices at boot time. Version 37.350 improved compatibility with ATA hard disks by increasing the wait time for disks to spin up during boot.  It is possible to upgrade the A600 to Workbench 2.1. This features a localization of the operating system in several languages and has a "CrossDOS" driver providing read/write support for FAT (MS-DOS)-formatted media such as floppy disks or hard drives. Workbench 2.1 was a software only update which runs on all Kickstart ROMs of the 2.0x family.  Following the release of AmigaOS 3.1 in 1994 it was possible to upgrade the A600 by installing a compatible revision 40.63 Kickstart ROM.

Bundled software.

In addition to the stock A600, mouse, power supply, and Workbench disk package, the A600 was available with the following software and hardware bundles:

The Amiga 600, also known as the A600 (codenamed "June Bug" after a B-52s song), is a home computer that was introduced at the CeBIT show in March 1992. The A600 is Commodore International's final model based on the Motorola 68000 CPU and the ECS chipset. It is essentially a redesign of the Amiga 500 Plus, with the option of an internal hard disk drive and a PCMCIA port. A notable aspect of the A600 is its small size. Lacking a numeric keypad, the A600 is only slightly larger than a standard PC keyboard (14" wide by 9.5" long by 3" high and weighing approximately 6 pounds). It shipped with AmigaOS 2.0, which was generally considered more user-friendly than earlier versions of the operating system.

L'A600, aussi nommé Amiga 600, fut le dernier ordinateur de la lignée des A500. Lancé à la fin 1991, il était essentiellement un A500 repackagé. L'intention de Commodore International était de faire remonter les ventes des A500 avant que le nouvel A1200, plus sophistiqué, devienne disponible.
