Sinclair ZX Spectrum 48K

Sinclair ZX · 1982

The machine that defined British gaming. Colour, sound and 48K for £175 in 1982, and a software industry — Ultimate, Ocean, Imagine — that grew up around it in bedrooms. The rubber keys and the attribute-clash colour are as famous as anything about it. Issue numbers matter to collectors, the early boards being both rarer and more failure-prone, and the ULA is the part that dies.
