The '''[[wikipedia:ZX81|ZX81]]''' was a Z80-based home computer produced by Sinclair Research and manufactured in Scotland by Timex Corporation released on March 5, 1981, and had a retail price of {{Inflation|USD|99.95|1981}}. It had a Z80 at 3.25 MHz with 1KB of RAM.
 
  
−
It was the successor to Sinclair's ZX80 and the predecessor of the [[ZX Spectrum emulators|ZX Spectrum]] and was hugely successful, and more than 1.5 million units were sold before it was discontinued.

'''No$''' ('''NoCash''') is a series of proprietary emulators, some of which are donationware, and accompanying tools/debuggers for a variety of systems, developed by Martin Korth.
−
The ZX81 was designed to be small, simple, and above all cheap, using as few components as possible to keep the cost down.
 
  
−
Video output was to a television set rather than a dedicated monitor. Programs and data were loaded and saved onto audio tape cassettes. It had only four silicon chips on board and a mere 1 KB of memory. The machine had no power switch or any moving parts and used a pressure-sensitive membrane keyboard for manual input.

Its distinctive design brought its designer, Rick Dickinson, a Design Council award.

The ZX81 could be bought by mail order in kit form or pre-assembled. It was the first cheap mass-market home computer that could be bought from high street stores, led by W.H. Smith and soon many other retailers.
 
  
−
The ZX81 marked the first time that computing in Britain became an activity for the general public, rather than the preserve of businesspeople and electronics hobbyists. The ZX81's commercial success made Sinclair Research one of Britain's leading computer manufacturers and earned a fortune and an eventual knighthood for the company's founder, Sir Clive Sinclair.
