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 NEC780-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 (pounds)79.95 or ready-built for

(pounds)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.
