Four-Phase Systems AL1
Four-Phase Systems was a computer company, founded by Lee Boysel and others, which built one of the earliest computers using semiconductor main memory and MOS LSI logic. The company was incorporated in February 1969 and had moderate commercial success. It was acquired by Motorola in 1981. History The idea behind Four-Phase Systems began when Boysel was designing MOS components at Fairchild Semiconductor in 1967. Boysel wrote a manifesto explaining how a computer could be built from a small number of MOS chips. Fairchild made Boysel head of a MOS design group, which he used to design parts satisfying the requirements of his putative computer. After doing this, Boysel left to start Four-Phase in October 1968, initially with two other engineers from his Fairchild group as well as others. Boysel was not sued by Fairchild, perhaps because of chaos caused by a change in Fairchild management at that time. When the company was incorporated in February 1969, he was joined by other ...

British Rail Class 81
The British Rail Class 81 is a class of Alternating current, AC electric locomotives that formerly operated on the West Coast Main Line of the London Midland Region of British Rail. Originally designated AL1, it was the first type of AC electric locomotive to be delivered to British Railways. History As part of the modernisation of the West Coast Main Line, which included electrification, 100 locomotives of five types were acquired; each type from a different manufacturer. The first locomotives to be delivered were type AL1, designed by British Thomson-Houston (BTH), an order being placed for 25 examples. Of these, 23 were for use on passenger trains with a top speed of 100 mph and were designated Type A. The other two locomotives were intended for freight train use, and geared for a top speed of 80 mph; these were designated Type B. Before the work was completed, BTH amalgamated with Metropolitan Vickers to form AEI (Associated Electrical Industries) traction divis ...

Main-belt Asteroid
The asteroid belt is a torus-shaped region in the Solar System, located roughly between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies, of many sizes, but much smaller than planets, called asteroids or minor planets. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. The asteroid belt is the smallest and innermost known circumstellar disc in the Solar System. About 60% of its mass is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid belt is calculated to be 3% that of the Moon. Ceres, the only object in the asteroid belt large enough to be a dwarf planet, is about 950 km in diameter, whereas Vesta, Pallas, and Hygiea have mean diameters less than 600 km. The remaining bodies range down to the size of a dust particle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AL Postcode Area
The AL postcode area, also known as the St Albans postcode area,Royal Mail, ''Address Management Guide'', (2004) is a group of ten postcode districts in England, within five post towns.
