Sinclair’s ZX Spectrum made its debut in 1982 and “was the first mainstream audience home computer in the UK.” Models were powered by a Zilog Z80 (3.5-MHz) CPU, 16kB or 48kB RAM, 16kB ROM, and “designed for use with contemporary portable television sets, for a simple colour graphic display.” Videos after the jump.

Originally dubbed the ZX82, the machine was later renamed the ZX Spectrum by Sinclair to highlight the machine’s colour display, compared to the black-and-white of its predecessor, the Sinclair ZX81
