year 1982
The Sinclair ZX Spectrum was a small home computer released in the United Kingdom in 1982 by Sinclair Research. Based on a Zilog Z80 CPU running at 3.50 MHz, the Spectrum came with either 16 KB or 48 KB of RAM. Originally dubbed the ZX82, the machine was later renamed the “Spectrum” by Sinclair to highlight the machine’s colour display, compared to the black-and-white of its predecessors, the ZX80 and ZX81. The rubber keyboard was marked with Sinclair BASIC keywords. Programs and data were stored using a normal cassette recorder.
