Sinclair ZX Spectrum

First released in 1982, the ZX Spectrum is Sinclair’s most well-known brand of home computer. Offering either 16k or 48k of RAM, the ZX Spectrum utilised the same CPU as the ZX80/ZX81, the Zilog Z80. There were 8 models of ZX Spectrum produced in its lifetime, ranging from the first rubber keyed ZX Spectrum, to the Spectrum +3 in 1987.

Competing primarily with the Commodore 64 and Amstrad CPC, the ZX Spectrum sold c. 5 million units. This was predominantly in Europe, but the ZX Spectrum certainly enjoyed most success in the UK.

Amazingly, over 24,000 pieces of software have been developed for the ZX Spectrum. With a still enthusiastic scene for the system, this number continues to increase.

The first ZX spectrum in it’s 16k and 48k guises were housed in a compact, neatly designed black unit. It has a membrane keyboard, but this time has actual rubber keys giving the user more feel than with the ZX80/ZX81. The sound on the system was delivered by an onboard ‘bleeper’, this is revered to this day and very much characterises the system.

The 16k and 48k rubber key ZX Spectrums were followed by the released of the ZX Spectrum+ in 1984. The Spectrum+ is essentially a 48k Spectrum but housed in a new case using an injection moulded keyboard.
