The Sinclair ZX80 was available in kit form, where buyers had to assemble and weld, and as a ready-to-use version at a slightly higher cost for those who did not have the skill or inclination to build their own unit. The Sinclair ZX80 was very popular from the start, and for some time there was a waiting list of several months for either version of the machine.

The BASIC of the Sinclair ZX80 and of the Sinclair ZX81 was written by John Grant, who said in 1985 "Certainly with the Spectrum we wanted to rewrite the code, but there was no time and definitely no resources". "At every point in the development of the ZX range, Clive wanted the maximum facilities at the lowest cost".

The Sinclair ZX80 was discontinued in August 1981, making way for its predecessor in Sinclair ZX81. The following is a vintage advertisement for this incredible first personal computer from Sinclair Research.
