Kōan (弘安) was a Japanese era name (年号,, nengō,, lit. "year name") after Kenji and before Shōō. This period spanned the years from February 1278 through April 1288. The reigning emperors were Go-Uda-tennō (後宇多天皇) and Fushimi-tennō (伏見天皇).
Kōan (康安) was a Japanese era name (年号, nengō, lit. year name) of the Northern Court during the Era of Northern and Southern Courts after Enbun and before Jōji. This period spanned the years from March 1361 through September 1362. The emperor in Kyoto was Go-Kōgon-tennō (後光厳天皇). Go-Kōgon's Southern Court rival in Yoshino during this time-frame was Go-Murakami-tennō (後村上天皇)
During the Meiji period, an Imperial decree dated March 3, 1911 established that the legitimate reigning monarchs of this period were the direct descendants of Emperor Go-Daigo through Emperor Go-Murakami, whose Southern Court (南朝, nanchō) had been established in exile in Yoshino, near Nara.
Until the end of the Edo period, the militarily superior pretender-Emperors supported by the Ashikaga shogunate had been mistakenly incorporated in Imperial chronologies despite the undisputed fact that the Imperial Regalia were not in their possession.

Pegasus was a video game system sold in Poland, Serbia, and Bosnia. It was a hardware clone of the Nintendo Famicom.
This particular Famiclone was hugely popular in Poland, Serbia, and Bosnia, where it has gained cult status, and is still widely available on auction websites and flea markets.
The system was manufactured in Taiwan by Micro Genius, and was built to resemble Nintendo's Famicom. Pegasus, like most known Famicom clones, was compatible with 60-pin Famicom cartridges, and partially compatible with some NES games, which could be played using a special converter. Original Nintendo games weren't popular however, due to raging piracy and lack of officially licensed products on the market. The majority of the games sold with and for the system were cheap pirated copies, manufactured mostly in Russia and China.
The typical retail set included the system, two detachable controllers (both with "turbo" buttons, which meant 4 buttons in total; 6-button controllers also existed.), a light gun (very similar in design to NES Zapper), power supply, RF cable, as well as audio-video RCA connectors. The system itself did not include any built-in games, but was bundled with a pirated cartridge labelled "Contra 168-in-1", which contained a few of the best-known NES titles, like Contra, Super Mario Bros., and Tetris, listed multiple times with slight variations. Most of the games had a "trainer" feature, which allowed the player to adjust the number of lives, and even the starting level of the game.
The Pegasus is a hovercraft vehicle made for educational purposes. The plans could be purchased from an article in the January 1984 issue of Popular Mechanics.
In the construction process, larger lawn mower engines could be added to lift a heavier payload.
Pegasus was an early vacuum tube (valve) computer built by Ferranti, Ltd of Great Britain.
The Pegasus 1 was first delivered in 1956 and the Pegasus 2 was delivered in 1959. Ferranti sold twenty-six copies of the Pegasus 1 and fourteen copies of the Pegasus 2, making it Ferranti's most popular valve computer.
At least two Pegasus machines survive, one in The Science Museum, London and one in The Manchester Museum of Science and Industry. The Pegasus in The Science Museum ran its first program in December 1959 and was regularly demonstrated until 2009 when it developed a severe electrical fault. In early 2014, the Science Museum decided to retire it permanently, effectively ending the life of one of the world's oldest working computers. The Pegasus officially held the title of the world's oldest computer until 2012, when the restoration of the Harwell computer was completed at the National Museum of Computing.
