The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. Launched in 1976, it was designed to be software-compatible with the Intel 8080 , offering a compelling alternative due to its better integration and increased performance.
Zilog, Inc. is an American manufacturer of microprocessors, microcontrollers, and application-specific embedded system-on-chip (SoC) products. The company was founded in 1974 by Federico Faggin and Ralph Ungermann, who were soon joined by Masatoshi Shima.
The X1 (エックスワン, Ekkusuwan), sometimes called the Sharp X1 [1] or CZ-800C [2], is a series of home computers released by Sharp Corporation from 1982 to 1988. [1] It is based on a Zilog Z80 CPU.

Zilog subsequently announced an agreement to manufacture the WE32100 chipset for a five year period, being the first alternative source of these products. [51] There was a Z8000 version of the Xenix Operating System. [52] In 1982, Digital Research and Zilog announced an agreement to make CP/M available for the Z8000. [53]
The 8-bit Zilog Z80 (1976) is at the core of the ZX Spectrum, MSX systems and many others. The 8086-based IBM PC, launched in 1981, started the move to 16-bit, but was soon passed by the 68000-based 16/32-bit Macintosh, then the Atari ST and Amiga.
The Zilog Z280 is a 16-bit microprocessor designed by Zilog as an enhancement of the Zilog Z80 architecture and integrating improvements from the abandoned Zilog Z800 project. First introduced in July 1987, the Z280 is considered to be a commercial failure.
SYmbiosis Multitasking Based Operating System (SymbOS) is a multitasking operating system for Zilog Z80-based 8-bit computer systems.. Unlike early 8-bit operating systems, SymbOS is based on a microkernel, which provides preemptive and priority-oriented multitasking and manages random-access memory (RAM) with a size of up to 1024 KB.
