ZX-80
<computer> Sinclair's cheap
personal computer with built-in
BASIC, launched at the end of January 1980 at a computer fair in Wembley, UK.
The processor was an
NEC 780-C running at 3.25 MHz.
It had 1KB of
RAM, externally expandable to 16KB, and 4KB of ROM.
It had RF video output to a TV, displaying 24 lines by 32 characters of monochrome text. An audio cassette recorder was used to save programs.
The ZX-80 was sold in kit form for £79.95 or ready-built for £99.95.
It 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.
The ZX-80 was succeeded by the
ZX-81.
