Editing Zilog Z8000 (section)

===Z80===
In the early 1970s, [[Intel]]'s management saw the [[microprocessor]] not so much as a product on its own, but as a way to create demand for their other products like [[static RAM]] and [[ROM]]. A reorganization in early 1974 further diluted the role of the microprocessor in the company. The designer of the [[Intel 4004]] and [[Intel 8080]], [[Federico Faggin]], decided to leave the company and start one dedicated to microprocessor design. Faggin left on 31 October 1974, joined by [[Ralph Ungermann]] and, later, the logic designer [[Masatoshi Shima]].{{sfn|Slater|2007|pp=2-3}}

Initially working on a concept for a simple [[microcontroller]], Faggin eventually concluded that the economics of the industry demanded that they introduce a product at the high-end, not the low-end. This led to a new concept initially known as the "Super 80", but eventually emerging as the [[Zilog Z80]]. The Z80 was a significant advance on the 8080, running on a single +5V power supply and adding several nice features from the [[Motorola 6800]]. Released in 1976, it was soon a huge hit.{{sfn|Slater|2007|p=4}}
