The Amstrad CPC is a series of 8-bit home computers produced by Amstrad between 1984 and 1990. It was designed to compete in the mid-1980s home computer market dominated by the Commodore 64 and the ZX Spectrum; it successfully established itself primarily in the United Kingdom, France, Spain, and the German-speaking parts of Europe.
The Sinclair QL is a personal computer launched by Sinclair Research in 1984, as an upper-end counterpart to the ZX Spectrum.
The ZX Spectrum is an 8-bit home computer developed and marketed by Sinclair Research. One of the most influential computers ever made and one of the all-time bestselling British computers, with over five million units sold. It was released in the United Kingdom on 23 April 1982, and around the world in the following years, most notably in Europe, the United States, and Eastern Bloc countries.
Sinclair BASIC is a dialect of the programming language BASIC used in the 8-bit home computers from Sinclair Research, Timex Sinclair and Amstrad. The Sinclair BASIC interpreter was written by Nine Tiles Networks Ltd.
The Timex Sinclair 1000 was the first computer produced by Timex Sinclair, a joint venture between Timex Corporation and Sinclair Research. It was launched in July 1982, with a US sales price of US$99.95, making it the cheapest home computer at the time; it was advertised as "the first computer under $100". The computer was aimed at regular home users. As purchased, the T/S 1000 was fully assembled and ready to be plugged into home televisions, which served as a video monitor. The T/S 1000 was a slightly modified version of the Sinclair ZX81 with an NTSC RF modulator, for use with North American TVs, instead of PAL for European TVs. The T/S 1000 doubled the onboard RAM from 1 KB to 2 KB; further expandable by 16 KB through the cartridge port. The T/S 1000's casing had slightly more internal shielding but remained the same as Sinclair's, including the membrane keyboard, which had modified nomenclature to suit American tastes Just like the ZX81, the T/S 1000 had black-and-white graphics and no sound.
Miles Gordon Technology, known as MGT, was a small British company, initially specialising in high-quality add-ons for the ZX Spectrum home computer. It was founded in June 1986 in Cambridge, England by Alan Miles and Bruce Gordon, former employees of Sinclair Research, after Sinclair sold the rights for the Spectrum to Amstrad. They moved to Swansea, Wales, in May 1989, became a public company in July 1989 and went into receivership in June 1990.
The ZX Interface 1, launched in 1983, was a peripheral from Sinclair Research for its ZX Spectrum home computer. Originally intended as a local area network interface for use in school classrooms, it was revised before launch to also act as the controller for up to eight ZX Microdrive high-speed tape-loop cartridge drives. It also included a DE-9 RS-232 interface capable of operating at up to 19.2 kbit/s. At hardware level it was fundamentally a voltage adaptor, the serial protocol being implemented in software by bit-banging. This led to problems when receiving data, but not when transmitting.
The Exatron Stringy Floppy is a continuous-loop tape drive developed by Exatron.
Sinclair Research Ltd is a British consumer electronics company founded by Clive Sinclair in Cambridge in the 1970s. In 1980, the company entered the home computer market with the ZX80 at £99.95, at that time the cheapest personal computer for sale in the United Kingdom. A year later, the ZX81 became available through retailers, introducing home computing to a generation, with more that 1.5 million sold. In 1982 the ZX Spectrum was released, becoming the UK's best selling computer, and competing aggressively against Commodore and Amstrad.
Timex Sinclair was a joint venture established in December 1982 between the British company Sinclair Research and Timex Corporation in an effort to gain an entry into the rapidly growing early-1980s home computer market in North America.
The 3480 tape format is a magnetic tape data storage format developed by IBM. The tape is one-half inch (13 mm) wide and is packaged in a 4 in × 5 in × 1 in cartridge. The cartridge contains a single reel; the takeup reel is inside the tape drive.
The One Per Desk, or OPD, was a British innovative hybrid personal computer and telecommunications terminal based on the hardware of the Sinclair QL. The One Per Desk was built by International Computers Limited (ICL) and launched in the United Kingdom in 1984. It was the result of a collaborative project between ICL, Sinclair Research and British Telecom, begun in 1983, which originally intended to incorporate Sinclair's flat-screen CRT technology.
The Rotronics Wafadrive is a magnetic tape storage peripheral launched in late 1984 for the ZX Spectrum home computer. Each tape is a continuous loop, unlike cassette tape. It was intended to compete with Sinclair's ZX Interface 1 and ZX Microdrive.
The Timex Computer 2048 or TC 2048 is a 1984 computer developed by Timex Portugal, at the time part of Timex Sinclair. It was based on the Timex Sinclair 2048 prototype, with a similar redesign case, composite video output, Kempston joystick interface, and additional video modes, while being highly compatible with the Sinclair ZX Spectrum computer.
The Timex FDD 3000 in 1982 was a nearly complete computer by Timex of Portugal. It began its development at Timex Computer Corporation in the U.S., but it was at Timex of Portugal that the work was finished.
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording.
The ZX Spectrum's software library was very diverse. While the majority of the software produced for the system was video games, others included programming language implementations, Sinclair BASIC extensions, databases, word processors, spread sheets, drawing and painting tools, and 3D modelling tools.
A floppy disk is a disk storage medium composed of a thin and flexible magnetic storage medium encased in a rectangular plastic carrier. It is read and written using a floppy disk drive (FDD). Floppy disks were an almost universal data format from the 1970s into the 1990s, used for primary data storage as well as for backup and data transfers between computers.
Touch Typist Typing Tutor is developed by Sector Software.
