The entire modern computer market would probably never have been born, at least in the way we know it, without the processor, Intel 8080, published 50 years ago. The Intel 8080 (“eighty-eighty”) is the second 8-bit microprocessor designed and manufactured by Intel. It first appeared in 1974.
The 8080 was not yet an x86 processor, but it was the company’s first real success and was instrumental in bringing PCs to an ever-larger audience.
8080 wasthe original target CPU for CP/M operating systems. The 8080 was quite widely used in early personal computers that run CP/M operating system. CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc.
The 8080 processor was the evolved to become Intel 8086 and to Zilog Z80. The Intel 8088/8086 processors started the IBM PC and compatible computers market.
The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. 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 and software-compatible with the Intel 8080, it offered a compelling alternative due to its better integration and increased performance. Very many home computers in 1980′s used Z80, for example Sinclair ZX Spectrum and MSX computers.
