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.

The Zilog Z80 was the first microprocessor created by Zilog, the first company entirely dedicated to microprocessors. It was started by Federico Faggin and Ralph Ungermann in November 1974. Faggin was Zilog's president and CEO until the end of 1980 and he conceived and designed the Z80 CPU and
CPU: Zilog Z80 @ 3.5 MHz; Memory: 4K RAM, expandable to 36K RAM; 8K ROM; Keyboard: 48-key rubber chiclet keyboard; Display: 80x72 semigraphics (40x24 text characters - with a 25th "zero" row at top - with a size of 8x8 pixels, equivalent to 320 x 192 pixels) in 16 colors (TEA1002 colour encoder) Sound: One voice, expandable to four voices
The Zilog eZ80 is an 8-bit microprocessor designed by Zilog as an updated version of the company's first product, the highly-successful Zilog Z80. The eZ80 is binary compatible with the Z80, but operating almost three times faster at the same clock frequency .
The program was designed to make Z80 machine code programming easier, [1] with full symbolic instructions, and an editing style similar to the Spectrum's built-in BASIC. Zeus Assembler was later re-released by the manufacturer of the ZX Spectrum, Sinclair Research. A Commodore 64 version was released in 1984. "Zeus 64 Assembler".
The NEC μCOM series is a series of microprocessors and microcontrollers manufactured by NEC in the 1970s and 1980s. The initial entries in the series were custom-designed 4 and 16-bit designs, but later models in the series were mostly based on the Intel 8080 and Zilog Z80 8-bit designs, and later, the Intel 8086 16-bit design.
The Micro-Professor MPF-I is a microcomputer released by Multitech (later renamed Acer) in 1981.The company's first branded product, it was marketed as a training system to learn machine code and assembly language for the Zilog Z80 microprocessor.
