The ZX80 was a revolutionary computer invented by Clive Sinclair and released in 1980. It was based upon the Z80 microprocessor, and used few other chips. It had a built in BASIC interpreter and introduced computing for the first time to the masses by being affordable by any household. Video display was produced by a domestic television set which was connected by an aerial fly-lead to the computer. A year later the ZX80 was replaced by the improved ZX81 which in turn was replaced in 1982 by the far superior ZX Spectrum. Research ZX80
