== History ==
In the early 1970s, Intel developed the 8080, one of the first widely used microprocessors. However, a group of engineers, led by Federico Faggin, who had worked on the originator of the 8080architecture in early 1972, left Intel to start their own company called Zilog in 1974.
At Zilog, Faggin and his team wanted to create an improved version of the 8080 that would be more efficient, flexible, and easier to use. This led to the development of the Z80, which was designed to be both backward-compatible with the 8080 and more powerful. This compatibility meant that any software written for the 8080 could run on the Z80, making it an attractive upgrade for manufacturers and developers.
