Who Manufactured the Sinclair ZX80 Before Sinclair Research?

The Sinclair ZX80 was originally manufactured by Science of Cambridge Ltd before the organization was renamed Sinclair Research. This transition occurred during the early 1980s as Clive Sinclair restructured his business operations to focus heavily on the burgeoning home computer market. Understanding this corporate evolution provides insight into the branding and legacy of one of the first computers priced under £100 in the United Kingdom.

Clive Sinclair had a history of founding electronics companies, starting with Sinclair Radionics. After leaving Radionics, he established Sinclair Instruments Ltd, which was subsequently renamed Science of Cambridge Ltd in 1978. It was under this specific entity that the ZX80 was developed and launched in February 1980. The machine was designed by Jim Westwood and marked a significant milestone in making computing accessible to the general public.

The rebranding to Sinclair Research Ltd took place in May 1981, following the success of the ZX80 and the release of its successor, the ZX81. This change aligned the company name more closely with the Sinclair brand identity that consumers recognized. Despite the name change, the core team and vision remained consistent, continuing to produce iconic machines like the ZX Spectrum. The distinction is important for collectors and historians tracing the lineage of Sinclair hardware.
