The Sinclair ZX Spectrum was a 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. The hardware designer was Richard Altwasser of Sinclair Research and the software was written by Steve Vickers on contract from Nine Tiles Ltd, the authors of Sinclair BASIC. Sinclair's industrial designer Rick Dickinson was responsible for the machine's outward appearance. 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.
