Story
​
The Zilog Z80 was an 8-bit processor, first launched on the market by the Zilog company founded by former Intel member Federico Faggin, in July 1976.
It was based on the Intel 8080 and became very popular in the 80s as it was part of several of the Sinclair computers. Specifically this type of processors were used in the "Sinclair ZX-80", "Sinclair ZX-81", "Sinclair Spectrum" in various versions, as well as the Amstrad CPC model.
From here, other manufacturers made the clones of this processor.
