History of the Microprocessor and the Personal Computer, Part 3 - TechSpot

With Motorola's delays and AMD's inability to produce its own competitive architecture, Zilog looked like the more attractive option given that as a relative newcomer it may have proved easier to work with and the Z8000 became AMD's choice. The Z8000's ...

The Z8000 is a 16-bit microprocessor introduced by Zilog in 1979. The architecture was designed by Bernard Peuto while the logic and physical implementation was done by Masatoshi Shima, assisted by a small group of people. The Z8000 was not Z80-compatible, and although it saw steady use well into the 1990s, it was not very widely used. However, the Z16C01 and Z16C02 Serial Communication Controllers still use the Z8000 core.
