The RadioShack TRS-80 Color Computer is a line of home computers based on the Motorola 6809 processor. The Tandy Color Computer line started in 1980 with what is now called the CoCo 1 and ended in 1991 with the more powerful CoCo 3. All three CoCo models maintained a high level of software and hardware compatibility, with few programs written for the older model being unable to run on the newer ones. Despite bearing the TRS-80 name, the Color Computer is a radical departure from the earlier TRS-80. In particular it has a Motorola 6809E processor, rather than the TRS-80's Zilog Z80; the machines in the Color Computer line are not compatible with software made for the earlier TRS-80. Tandy Corporation announced the TRS-80 Color Computer in July 1980 to compete with the inexpensive and popular Commodore VIC-20, it began as a joint venture between Tandy and Motorola Semiconductor, Inc. of Austin, to develop a low-cost home computer in 1977. The initial goal of this project, called "Green Thumb", was to create a low cost Videotex terminal for farmers and others in the agricultural industry.
This terminal would connect to a phone line and an ordinary color television and allow the user access to near-real-time information useful to their day-to-day operations on the farm. Motorola's MC6847 Video Display Generator chip was released about the same time as the joint venture started and it has been speculated that the VDG was designed for this project. At the core of the prototype "Green Thumb" terminal, the MC6847, along with the MC6809 microprocessor unit, made the prototype a reality by about 1978; the prototype contained too many chips to be commercially viable. Motorola solved this problem by integrating all the functions of the many smaller chips into one chip, the MC6883 Synchronous Address Multiplexer. By that time in late 1979, the new and powerful Motorola MC6809 processor was released; the SAM, VDG, 6809 were combined and the AgVision terminal was born. The AgVision terminal was sold through Radio Shack stores as the VideoTex terminal around 1980. Internal differences, if any, are unclear.
With its proven design, the VideoTex terminal contains all the basic components for a general-purpose home computer. The internal modem was removed, I/O ports for cassette storage, serial I/O, joysticks were provided. An expansion connector was added to the right side of the case for future enhancements and program cartridges, a RAM button covers the hole where the Modem's LED "DATA" indicator had been. On July 31, 1980, Tandy announced the TRS-80 Color Computer. Sharing the same case and layout as the AgVision/VideoTex terminals, at first glance it would be hard to tell the TRS-80 Color Computer from its predecessors. Tandy viewed businesses as its primary market for computers. Although the company's Ed Juge said in 1981 that the Color Computer was "our entry into the home-computer market", he described it as "for serious professionals", stating that a word processor and spreadsheet would soon be available. In 1987 Tandy CEO John Roach refused to describe it as a home computer; the initial model shipped with 4 KB of Dynamic Random Access Memory and an 8 kB Microsoft BASIC interpreter in ROM.
Its price was 399 USD. Within a few months, Radio Shack stores across the US and Canada began receiving and selling the new computer; the Color Computer, with its Motorola 6809E processor, is different from the Zilog Z80-based TRS-80 models. Indeed, the "80" in "TRS-80" stands for "Z80". For a time, the CoCo was referred to internally as the TRS-90 in reference to the "9" in "6809". However, this was dropped and all CoCos sold as Radio Shack computers were called TRS-80 in spite of the processor change; the CoCo is incompatible with all software for other Tandy compurters. Like its Z80-based predecessors, the CoCo shipped with a version of BASIC. Tandy licensed Microsoft BASIC; the original CoCo offered standard Color BASIC and Extended Color BASIC. This was further extended by a Disk Extended Color BASIC ROM included in the floppy controller; the CoCo 3 included Super Extended Color BASIC as deploying extensions added by Microware. Third-party floppy controller ROMs, such as J&M System JDOS, DSS Peripherals Disk Controller, enabled the use of double-sided disk drives.
The CoCo BASIC offered a number of advanced sound and program control features many of which would appear in IBM PC-compatible versions of Microsoft BASIC, these included statements for playing musical notes and drawing graphics primitives. These advanced features were possible on the 8-bit CoCo because 6809 machine language was more code-dense than Z80 or 6502 machine language, thus more features could be packed into a small BASIC ROM; the CoCo is designed to be attached to a color television set, whereas the Z80 machines use monochrome computer monitors built into the case. The CoCo features an expansion connector for program cartridges and other expansion devices, such as floppy-disk controllers and modems. Tandy released a Multi-Pak Interface which allowed switching among four cartridges; this is similar in concept to the Model I's Expansion Interface. The CoCo did not have internally-mounted disk drives and instead reverted to the TRS-80 Model I setup with separate external drives in a daisy chain, each unit requiring a separate wall outlet for power.
Failure causes are defects in design, quality, or part application, which are the underlying cause of a failure or which initiate a process which leads to failure. Where failure depends on the user of the product or process human error must be considered. A part failure mode is the way. A part has only a few failure modes, thus a relay may fail to close contacts on demand. The failure mechanism that caused this can be of many different kinds, multiple factors play a role at the same time, they include corrosion, welding of contacts due to an abnormal electric current, return spring fatigue failure, unintended command failure, dust accumulation and blockage of mechanism, etc. Only one cause can be identified that creates system failures; the real root causes can in theory in most cases be traced back to some kind of human error, e.g. design failure, operational errors, management failures, maintenance induced failures, specification failures, etc. A scenario is the complete identified possible sequence and combination of events, conditions, system states, leading to an end system state.
It starts from causes leading to one particular end effect. A failure scenario is for a system the same. Both result in a failure mode of the system / component. Rather than the simple description of symptoms that many product users or process participants might use, the term failure scenario / mechanism refers to a rather complete description, including the preconditions under which failure occurs, how the thing was being used and ultimate/final causes, any subsidiary or resulting failures that result; the term is part of the engineering lexicon of engineers working to test and debug products or processes. Observing and describing failure conditions, identifying whether failures are reproducible or transient, hypothesizing what combination of conditions and sequence of events led to failure is part of the process of fixing design flaws or improving future iterations; the term may be applied to mechanical systems failure. Some types of mechanical failure mechanisms are: excessive deflection, ductile fracture, brittle fracture, creep, thermal shock, corrosion, stress corrosion cracking, various types of fatigue.
Each produces a different type of fracture surface, other indicators near the fracture surface. The way the product is loaded, the loading history are important factors which determine the outcome. Of critical importance is design geometry because stress concentrations can magnify the applied load locally to high levels, from which cracks grow. Over time, as more is understood about a failure, the failure cause evolves from a description of symptoms and outcomes to a systematic and abstract model of how and why the failure comes about; the more complex the product or situation, the more necessary a good understanding of its failure cause is to ensuring its proper operation. Cascading failures, for example, are complex failure causes. Edge cases and corner cases are situations in which complex and difficult-to-debug problems occur. Materials can be degraded by their environment by corrosion processes, such as rusting in the case of iron and steel; such processes can be affected by load in the mechanisms of stress corrosion cracking and environmental stress cracking.

Clinton Merrick Hurdle is an American former professional baseball outfielder and former manager of the Pittsburgh Pirates of Major League Baseball. Hurdle played in MLB for the Kansas City Royals, Cincinnati Reds, New York Mets, St. Louis Cardinals, has managed for the Colorado Rockies. Labeled a "phenom" by Sports Illustrated at age twenty, Hurdle played 515 games at the major league level. After retiring from playing baseball, Hurdle became a manager, his eight seasons with the Colorado Rockies included leading the 2007 club to the franchise's first National League pennant. On November 14, 2010, the Pirates hired him to be their manager. In 2013, Hurdle led them to their first winning season and playoff appearance since 1992, he was named the NL Manager of the Year that season. Clint Hurdle is named for his father, who played collegiate baseball for Ferris State University; when Hurdle was four years old, the family moved from Michigan to Florida so his father could take a job at the Kennedy Space Center.
As a child, Hurdle was a bat boy for the Cocoa Astros of the Florida State League. Hurdle graduated from Merritt Island High School in Florida, he received a scholarship from the University of Miami to play college baseball and college football as a quarterback, was accepted to Harvard University as well, but declined both to play professional baseball instead. Hurdle has been divorced twice. Hurdle is a recovering alcoholic and an advocate of Alcoholics Anonymous and other addiction treatment programs as well as for the Prader-Willi Syndrome Association. Janalee Heinemann, director of research and medical affairs for Prader-Willi Syndrome Association USA, told the Pittsburgh Tribune-Review, “For a lot of people, it takes time to regroup and think through things, but from the time was a newborn, he was willing to be honest and say what she had and spread awareness. A lot of people in his position would just say, ‘I'm going to the best doctors and am doing this all privately,' because they can, but it wasn't enough to just help his kid.
He wanted to help all kids.” The Kansas City Royals selected Hurdle in the first round, with the ninth overall selection, of the 1975 Major League Baseball draft. He signed with the Royals, he made his major league debut with the Royals in 1977, in 1978 was featured on the cover of Sports Illustrated on March 20 with the headline: "This Year's Phenom."Hurdle played for the Royals through 1981, but never achieved the level of play suggested by his high draft position. Hurdle had his best year in 1980 starting 109 regular season games in right field for the American League pennant winning Royals. Hurdle started at right field in 4 games during the 1980 World Series against the Philadelphia Phillies, he was traded to the Cincinnati Reds in December 1981, after spending 1982 with the Reds, went on waivers. In February 1983 he was signed by the Seattle Mariners before being released. In April 1983 he was signed by the New York Mets where he spent the majority of the season with their Triple-A affiliate Tidewater Tides.
During the 1983 season, Hurdle set a franchise record for the Tides with 105 runs batted in. He played in 13 games with the Mets. In 1984 he again played for the Tidewater Tides. In 1985 he played in 43 games for the Mets and in 1986 he played in 78 games for the St. Louis Cardinals. Hurdle ended his baseball career in 1987 at the age of 29 by playing in 97 games for the Tidewater Tides and 3 games for the Mets. In addition to right field, during his career he played first base, third base and designated hitter. Hurdle played three different seasons of winter ball for Tiburones de La Guaira of the Venezuelan Professional Baseball League. In his first season, 1977–78, he led the league in home runs while batting.305 with 52 RBIs. He played again in 1979-80 and 1983-84, he led the Venezuelan league in walks all three seasons. After ending his playing career in 1987, Hurdle began his managerial career the next year when he was named Manager of the St. Lucie Mets of the Class A-Advanced Florida State League in 1988.
He served as Manager for the Jackson Mets of the Class AA Texas League, Williamsport Bills of the Class AA Eastern League, the Tidewater/Norfolk Tides of the Class AAA International League. In 1994 he joined the Colorado Rockies organization as the minor league hitting instructor, serving in that capacity until he was named the Rockies hitting coach in 1997. Hurdle was promoted to Manager in 2002 following the early-season firing of Buddy Bell. On April 2, 2006, he was given a two-year contract extension. In 2007, Hurdle managed Colorado to a record of 90-73, their best finish in the team's 15-year history. Colorado defeated San Diego. Hurdle's Rockies beat the Philadelphia Phillies in the Division Series, sweeping them in three games to force a match-up with their rival Arizona Diamondbacks in the NLCS; the Rockies continued their improbable streak by sweeping Arizona in four games to win the first pennant in team history and reach the 2007 World Series. In the World Series, Colorado faced the Boston Red Sox.
But the winning ways came to an end, the Rockies were swept in four games. Injuries to several regulars caused the Rockies to fade in 2008, after a poor s
