The first historical accounts of walnut trees growing under civilized cultivation was in ancient Babylon (Iraq) about 2000 B.C.; however, walnuts have evidently been attached to mankind much earlier by excavations from cave fossils as suggested by archeologists. There is a reference point in the Biblical record in the Old Testament, that King Solomon was growing nuts (identified as walnuts by some translators), however, the likelihood of these nuts being other than almonds is very remote, because of the almond nut image that was used as symbols commonly in Hebrew icons and stone carving displays in Jerusalem inside Solomon's temple. The adaptability of almonds is much more likely for almond trees to succeed than for walnut trees in the climate and soils of Israel.
The Greeks were credited with the first certified improvements in the size and quality of the Persian (Iran and Iraq) today called English walnut trees through selection and cultivation. The Romans soon established the Persian walnut trees throughout most of Europe and much of North Africa, that have most popularly become known today as the English walnut trees.
English Walnuts, ?Juglans regia,? were brought into the United States by Spanish missionaries in the early 1800's by Franciscan monks, who settled along the California coast. Because the English walnut orchards, that were rapidly established in Central California came from the seeds planted from those walnuts that grew in the Catholic missions, the walnuts were sold and distributed under the name ?Mission Walnuts.?
Central California walnut tree growers today produce 99% of the total U.S. commercial walnut supplies of English walnuts. This production capacity of California also produces 65% of the world supply of English walnuts.
Famous chefs of the world use walnuts in many types of cuisines including meats, vegetables, desserts, and soup preparations. A world famous dessert--made from walnuts, honey, and paper-thin, buttered, flakes of crusts--is called ?Baklava.?
Important commercial types of walnuts that are grown today for profit are ?Juglans regia,? the English (Persian) walnut, that is mainly grown and produced in the United States. Trees can live to an age of approximately 60 years and grow to about 60 feet tall at maturity.
Black walnut, ?Juglans nigra,? a native walnut tree in America is grown mainly from New England to Minnesota and Nebraska and southwards down to the Gulf of Mexico. The black walnut tree can grow to a height of 60 feet and can live past 100 years. Black walnut trees have been grown mainly for their value in making expensive furniture; the nuts are harvested in considerably large quantities to use in baking, ice cream, and in candy recipes. The nuts can be easily shelled into large pieces if soaked overnight in water. The nuts are known for their crunchy flavor, which is distinctively spicy and enriched in its oil content.
Butternut or White walnut, ?Juglans cinerea,? is genetically closely related to the black walnut, ?Juglans nigra,? that forms oval shaped nuts, with a thick corrugated shell, 2 inches long with white kernels; richly flavored and preferred by many people to have a superior flavor over other cultivars of walnuts. The white walnut can grow 100 feet tall with a life expectancy of 75 years. The white walnut tree is the most cold hardy of all walnut trees, growing vigorously in zones 3-9. The roots of these trees, like black walnut trees, will exude a poisonous chemical that kills other plants (phytotoxic) growing nearby, thus other vegetation does not grow well if located within 80 feet of the trunk of the tree. The tree has a broader, leafy canopy than other walnut trees, but the wood is soft and inferior.
Walnut kernels are universally known to contain many antioxidants that offer health benefits and will lower cholesterol in the body, thus lowering heart damage from disease and cause a dramatic reduction of fatty coagulants in veins and arteries. The leaves have been used as a laxative since antiquity, as well as to induce vomiting, stop bleeding, stop diarrhea, as a cure to many skin diseases and herpes, and to kill human internal worms. Walnut hull extracts have been used to treat liver problems, to kill ringworms, and to help lose weight. Walnuts are highly beneficial in providing all of the Vitamin B series, Vitamin E, and many minerals that are beneficial to keeping a healthy body.
Walnut hulls have found many uses in a powdered state as a metal polish, as a thermal insulator in rocket nose cones and as a mysterious, secret ingredient in women's cosmetics. Walnut tree extracts have been used for centuries to make ink and dyes. The Egyptians used walnut kernel oil to embalm mummies by replacing the blood with walnut oil.
Greek mythology records that Carya, (the Latin genus name for walnut), who fell in love with the Greek God, Dionysus, was transformed into a walnut tree at her death. The wooden walnut columns (and later, marble) at the Acropolis that stand above the city were transformed into her human image (catyatides) that today can be seen by tourists in Athens, Greece.
Luther Burbank in 1893 introduced fast growing walnut tree hybrids that only required 15 years of growth to reach maturity, rather than the usual 50-60 years of growth. One hybrid he named, ?Paradox walnut tree,? Juglans x ?Paradox? by crossing the English walnut tree, ?Juglans regia,? with the California black walnut, ?Juglans hindsii.? This walnut tree is used as a grafting understock for commercial cultivars. ?Royal walnut tree,? Juglans x ?Royal,? by crossing the American black walnut tree, ?Juglans nigra,? with the California black walnut, ?Juglans hindsii.? This walnut tree still today produces almost a ton of nuts per year.
Other minor species of walnuts include the ?Heartnut walnut tree,? ?Juglans ailantifolia,? that is as hardy as the American black walnut, easily grown, very productive, especially after the trees grow older. It bears strings of nuts sometimes 30 or more in a single cluster that hangs down 1 foot in length. The kernels of these heartnut walnuts drop out into a container completely intact when the thin shells are cracked. Luther Burbank felt that this walnut was an intermediate variant of the Japanese walnut. The Manchurian walnut tree, ?Juglans mandshurica,? was introduced as a variant of the Japanese walnut during the Civil War of the United States. The flavor of these nuts is considered spicy and superior in taste to other walnuts, while being crunchier. These trees grow to 100 feet tall or more and are cold hardy from zones 5 to 10. This walnut tree produces a staple food crop in Korea (Manchuria). Many excellent food products are available using the nuts from this walnut tree.

In the early 1980s, the computer gaming industry experienced its first major growing pains. Publishing houses appeared, with many honest businesses (and in rare cases such as Electronic Arts, successfully surviving to this day) alongside fly-by-night operations that cheated the games' developers. While some early 80s games were simple clones of existing arcade titles, the relatively low publishing costs for personal computer games allowed for many bold, unique games, a legacy that continues to this day. The primary gaming computers of the 1980s emerged in 1982: the Commodore 64 and ZX Spectrum.
The Golden age of arcade games reached its full steam in the 1980s, with many technically innovative and genre-defining games in the first few years of the decade. Defender (1980) established the scrolling shooter and was the first to have events taking place outside the player's view, displayed by a radar view showing a map of the whole playfield. Battlezone (1980) used wireframe vector graphics to create the first true three-dimensional game world. 3D Monster Maze (1981) was the first 3D game for a home computer, while Dungeons of Daggorath (1982) added various weapons and monsters, sophisticated sound effects, and a "heartbeat" health monitor. Pole Position (1982) used sprite-based, pseudo-3D graphics when it pioneered the "rear-view racer format" where the player's view is behind and above the vehicle, looking forward along the road with the horizon in sight. The style would remain in wide use even after true 3D graphics became standard for racing games. Pac-Man (1980) was the first game to achieve widespread popularity in mainstream culture and the first game character to be popular in his own right. Dragon's Lair (1983) was the first laserdisc game, and introduced full-motion video to video games.
With Adventure establishing the genre, the release of Zork in 1980 further popularized text adventure games in home computers and established developer Infocom's dominance in the field. As these early computers often lacked graphical capabilities, text adventures proved successful. When affordable computers started catching up to and surpassing the graphics of consoles in the late 1980s, the games' popularity waned in favor of graphic adventures and other genres. The text adventure would eventually be known as interactive fiction and a small dedicated following has kept the genre going, with new releases being nearly all free.
Also published in 1980 was Roberta Williams' Mystery House, for the Apple II. It was the first graphic adventure on home computers. Graphics consisted entirely of static monochrome drawings, and the interface still used the typed commands of text adventures. It proved very popular at the time, and she and husband Ken went on to found Sierra On-Line, a major producer of adventure games. Mystery House remains largely forgotten today.
The Commodore 64 systemIn August of 1982, the Commodore 64 was released to the public. It found initial success because it was marketed and priced aggressively. It had a BASIC programming environment and advanced graphic and sound capabilities for its time, similar to the Colecovision console. It would become the most popular home computer of its day in the USA and many other countries and the best-selling single computer model of all time internationally.
At around the same time, the ZX Spectrum was released in the UK and quickly became the most popular home computer in most of Western Europe, and later the Soviet bloc due to the ease with which clones could be produced.
SuperSet Software created Snipes, a text-mode networked computer game in 1983 to test a new PC based computer network and demonstrate its capabilities. Snipes is officially credited as being the original inspiration for Novell Netware. It is believed to be the first network game ever written for a commercial personal computer and is recognised alongside 1974's Maze War (a networked multiplayer maze game for several research machines) and Spasim (a 3d multiplayer space simulation for time shared mainframes) as the precursor to multi-player games such as Doom and Quake.
The true modern adventure game would be born with the Sierra King's Quest series in 1984. It featured color graphics and a third person perspective. An on-screen player-controlled character could be moved behind and in front of objects on a 2D background drawn in perspective, creating the illusion of pseudo-3D space. Commands were still entered via text. Lucasarts would do away with this last vestige feature of text adventures when its 1987 adventure Maniac Mansion built with its SCUMM system allowed a point-and-click interface. Sierra and other game companies quickly followed with their own mouse-driven games. For more on the history of adventures games, see Adventure games, history of
With Elite in 1984, David Braben and Ian Bell ushered in the age of modern style 3d graphics in the home, bringing a convincing vector world with full 6 degree freedom of movement and thousands of visitable planetary systems into the living room. Initially only available for the BBC Micro and Acorn Electron, the success of this title caused it eventually to be ported to all popular formats, including the Commodore 64, ZX Spectrum, Commodore Amiga, Atari ST and even the Nintendo Entertainment System, although this version only received a European release.
The personal computer became a competitive gaming platform with IBM's PC/AT in 1984. The new 16-color EGA display standard allowed its graphics to approach the quality seen in popular home computers like the Commodore 64. Sound however, was still only the crude bleeps of PC speakers. The primitive 4-color CGA graphics of previous models had limited the PC's appeal to the business segment, since its graphics failed to compete with the C64 or Apple II.
The Apple Macintosh also arrived at this time. It lacked the color capabilities of the earlier Apple II, instead preferring a much higher pixel resolution, but the operating system support for the GUI attracted developers of some interesting games (e.g. Lode Runner) even before color returned in 1987 with the Mac II.
In computer gaming, the later 1980s are primarily the story of the United Kingdom's rise to prominence. The market in the U.K. was primely positioned for this task: personal computer users were offered a smooth scale of power versus price, from the ZX Spectrum up to the Amiga, developers and publishers were in close enough proximity to offer each other support, and the NES made much less of an impact than it did in the United States, being outsold by the Master System.
The arrival of the Atari ST and Commodore Amiga in 1985 was the beginning of a new era of 16-bit machines. For many users they were too expensive until later on in the decade, at which point advances in the IBM PC's open platform had caused the IBM PC compatibles to become comparably powerful at a lower cost than their competitors. The VGA standard developed for IBM's new PS/2 line in 1987 gave the PC the potential for 256-color graphics. This was a big jump ahead of most 8-bit home computers but still lagging behind platforms with built-in sound and graphics hardware like the Amiga, causing an odd trend around '89-91 towards developing to a seemingly inferior machine. Thus while both the ST and Amiga were host to many technically excellent games, their time of prominence proved to be shorter than that of the 8-bit machines, which saw new ports well into the 80s and even the 90s.
AdLib set an early defacto standard for sound cards in 1987, with its card based on the Yamaha YM3812 sound chip. This would last until the introduction of Creative Labs' Sound Blaster in 1989, which took the chip and added new features while remaining compatible with AdLib cards, and creating a new defacto standard. However, many games would still support these and rarer things like the Roland MT-32 and Disney Sound Source into the early 90s. The initial high cost of sound cards meant they would not find widespread use until the 1990s.
Shareware gaming first appeared in the late 1980s, but its big successes came in the 1990s.
