Z80

A family of 8-bit microprocessors from Zilog. The original Z80 chip was the successor to the Intel 8080 and was widely used in first-generation personal computers that used the CP/M operating system. Subsequent Z180, Z280 and Z380 chips have been widely used in embedded systems, and hundreds of millions of them have been shipped. See eZ80.
