<computer> Sinclair's cheap Zilog Z80-based personal computer with built-in BASIC and one kilobyte of RAM, launched in 1979. The ZX-80 was originally sold in kit form and was used by many UK hobbyists as a means of learning the basics of computing.
Some remember the 1kb ZX-80 for the claim in its advertising that you could control a nuclear power station with it. I was succeeded by the ZX-81.
