Intel 8080 microprocessor is a successor to the Intel 8008 CPU. The 8080 was designed by Federico Faggin and Masatoshi Shima. Stan Mazor contributed to chip design. The work on 8080 microprocessor was started at the end of 1972, and the CPU was released in April of 1974. Original version of the 8080 had a flow - it could only drive low-power TTL devices. After the flow was discovered Intel released updated version of the CPU - 8080A, which could drive standard TTL devices.

The Intel 8080A is a complete 8-bit parallel central processing unit. It is fabricated on a single LSI chip using Intel´s n-channel silicon gate MOS process. This offers the user a high performance solution to control and processing applications. The 8080A contains six 8-bit general purpose working registers and an accumulator. The six general purpose registers may be addressed individually or in pairs providing both single and double precision operators. The 16-bit stack pointer controls the addressing of an external stack.

The Intel 8080 microprocessor has seven CPU registers, one which is an accumulator register. As a consequence, the processor has some of the characteristics of a general register type and some of the characteristics of an accumulator type.

In 1974, The Intel 8080 was released, and became the power behind the very first personal computer, called the Altair. In 1976, the Intel 8085 was released. The Intel 8086 surfaced in 1978. In 1979, Intel released the Intel 8088, which caught the attention of IBM, who chose to use Intel's 8088 Processor as the base in their new Personal Computer system. In 1982, Intel released the Intel 80186, and the Intel 80286 processors, often shortened now to just '186' and '286', respectively. In 1985, Intel uncovered it's codenamed P3 Chip, called the 386 often shortened to i386, which heralded the birth of the IA-32 Instruction set.

An early OS for microcomputer by Gary Kildall of Digital Research for Intel 8080 and Zilog Z80 based 8-bit computers. Actually, when Kildall started writing CP/M, in 1973-4, he didn't have an 8080 system; the first versions were tested on an 8080 emulator for PDP systems. In addition to CP/M-80, DR ... created CP/M-86 (works on modern wintel PCs), CP/M-68k (for MC68000 systems), CP/M-Z8k (for Zilog Z8000 systems), and MP/M (a multitasking version), among others.

Federico Faggin was the originator of the 8080 architecture in early 1972, proposed it to Intel's management and pushed for its implementation. He finally got the permission to develop it six months later. Faggin hired Masatoshi Shima from Japan who did the detailed design under his direction. Stan Mazor contributed a couple of instructions to the instruction set.
