zx spectrum

The ZX Spectrum (UK: ) is an 8-bit home computer developed and marketed by Sinclair Research. Considered one of the most influential computers ever made, it is also one of the best-selling British computers ever, 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.
The machine was designed by English entrepreneur and inventor Sir Clive Sinclair and his small team in Cambridge. It was made to be small, simple, and most importantly inexpensive, with as few components as possible. The addendum "Spectrum" was chosen to highlight the machine's colour display, which differed from the black-and-white display of its predecessor, the ZX81. Rick Dickinson designed its distinctive case, rainbow motif, and rubber keyboard. Video output is transmitted to a television set rather than a dedicated monitor, while software is loaded and saved onto compact audio cassettes.
The ZX Spectrum was initially distributed through mail order, but after severe backlogs it was sold through High Street chains in the United Kingdom. It was released in the U.S. as the Timex Sinclair 2068 in 1983, and in some parts of Europe as the Timex Computer 2048. Ultimately the Spectrum was released as seven different models, ranging from the entry level with 16 KB RAM released in 1982 to the ZX Spectrum +3 with 128 KB RAM and built-in floppy disk drive in 1987. Throughout its life, the machine primarily competed with the Commodore 64, BBC Micro, Dragon 32, and the Amstrad CPC range. Over 24,000 different software products were released for the ZX Spectrum.
The Spectrum played a pivotal role in the early history of personal computing and video gaming, leaving an enduring legacy that influenced generations. Its introduction led to a boom in companies producing software and hardware, the effects of which are still seen. It was among the first home computers aimed at a mainstream audience, with some crediting it as responsible for launching the British information technology industry. The Spectrum is one of the best-selling British computers of all time, retaining the title of Britain's top-selling computer until the Amstrad PCW surpassed it in the 1990s. It was discontinued in 1992.
