Amiga 3000The Amiga 3000, or A3000, is a personal computer released by Commodore in June 1990. It is the successor to the Amiga 2000 and its upgraded model Amiga 2500 with more processing speed, improved graphics, and a new revision of the operating system. Its predecessors, the Amiga 500, 1000 and 2000, share the same fundamental system architecture and consequently perform without much variation in processing speed despite considerable variation in purchase price. The A3000 however, was entirely reworked and rethought as a high-end workstation.
Disk operating systemA disk operating system (DOS) is a computer operating system that resides on and can use a disk storage device, such as a floppy disk, hard disk drive, or optical disc. A disk operating system provides a for organizing, reading, and writing on the storage disk, and a means for loading and running programs stored on that disk. Strictly, this definition does not include any other functionality, so it does not apply to more complex OSes, such as Microsoft Windows, and is more appropriately used only for older generations of operating systems.
Amiga models and variantsThis is a list of models and clones of Amiga computers. The first Amiga computer was the "Lorraine" developed using the Sage IV system. It consisted of a stack of breadboarded circuit boards. These models are not hardware compatible with the 68k Amigas. These chipsets were planned but never fabricated. Some computers were released by other companies which were AmigaOS compatible. DraCo: Released by MacroSystem in 1994. This was a high end machine which ran AmigaOS 3.1, but did not include the Amiga chipset, instead using a graphics card.
DemosceneThe demoscene is an international computer art subculture focused on producing demos: self-contained, sometimes extremely small, computer programs that produce audiovisual presentations. The purpose of a demo is to show off programming, visual art, and musical skills. Demos and other demoscene productions (graphics, music, videos, games) are shared at festivals known as demoparties, voted on by those who attend and released online. The scene started with the home computer revolution of the early 1980s, and the subsequent advent of software cracking.
MorphOSMorphOS is an AmigaOS-like computer operating system (OS). It is a mixed proprietary and open source OS produced for the Pegasos PowerPC (PPC) processor based computer, PowerUP accelerator equipped Amiga computers, and a series of Freescale development boards that use the Genesi firmware, including the Efika and mobileGT. Since MorphOS 2.4, Apple's Mac mini G4 is supported as well, and with the release of MorphOS 2.5 and MorphOS 2.6 the eMac and Power Mac G4 models are respectively supported. The release of MorphOS 3.
Sinclair ResearchSinclair Research Ltd is a former British consumer electronics company founded by Clive Sinclair in Cambridge. It was originally incorporated in 1973 as Westminster Mail Order Ltd, renamed Sinclair Instrument Ltd, then Science of Cambridge Ltd, then Sinclair Computers Ltd, and finally Sinclair Research Ltd. It remained dormant until 1976, when it was activated with the intention of continuing Sinclair's commercial work from his earlier company Sinclair Radionics, and adopted the name Sinclair Research in 1981.
AmstradAmstrad was a British electronics company, founded in 1968 by Alan Sugar at the age of 21. The name is a contraction of Alan Michael Sugar Trading. It was first listed on the London Stock Exchange in April 1980. During the late 1980s, Amstrad had a substantial share of the PC market in the UK. Amstrad was once a FTSE 100 Index constituent, but since 2007 has been wholly owned by Sky UK. , Amstrad's main business was manufacturing Sky UK interactive boxes.
KIM-1The KIM-1, short for Keyboard Input Monitor, is a small 6502-based single-board computer developed and produced by MOS Technology, Inc. and launched in 1976. It was very successful in that period, due to its low price (thanks to the inexpensive 6502 microprocessor) and easy-access expandability. MOS Technology's first processor, the 6501, could be plugged into existing motherboards that used the Motorola 6800, allowing potential users (i.e. engineers and hobbyists) to get a development system up and running very easily using existing hardware.
