It was designed to be small, simple, and most importantly inexpensive, with as few components as possible. Referred to during development as both the ZX81 Colour and the ZX82, the ZX Spectrum was designed by a small team in Cambridge.
The machine was the brainchild of English entrepreneur and inventor Sir Clive Sinclair. Many official and unofficial clones were released around the world in the following years, most notably in Europe, the United States, and Eastern Bloc countries. It was first released in the United Kingdom on 23 April 1982. The ZX Spectrum ( UK: / z ɛ d ɛ k s/) is an 8-bit home computer developed and marketed by Sinclair Research.
