ZX Spectrum
The ZX Spectrum was a range of home computers based on the Z80 microchip and sold by Sinclair Research Ltd, the business company owned by British inventor Sir Clive Sinclair. The computer was first produced in April of 1982 as part of a project to sell computers for a low price that any family could afford. The ZX sold more than any other computer at that time in Britain and Spain. The first ZX was especially known for being very small and relatively cheap. The keyboard was made of rubber and the casing was made of plastic.
