The ZX Spectrum is 30 years old. The successor to Sir Clive Sinclair’s ZX81 - at the time the world’s best selling consumer computer - it introduced colour “high resolution” graphics and sound.
It also offered an extended version of Sinclair Basic, a computer language with which hundreds of thousands of users were already familiar.
The thin Bauhaus-inspired design was sleeker than anything else on the market, but what was more impressive was its price: £125 for the basic model with 16 kilobytes of RAM, or £175 for the 48k model.
That allowed adverts at the time to boast: “Less than half the price of its nearest competitor- and more powerful”.
Sir Clive believed hitting the low price points was crucial.
