==History==
The 8080 is often said to be the "first truly usable microprocessor". This CPU was 10 times faster than its predecessor, the [[Intel 8008]] issued in 1972.
Its predecessor was the first 8-bit microprocessor, the [[Intel The 8008]]. It had, among other limitations, a rigid seven-level address call stack instead of a flexible Stack Pointer. The 8008 instruction set was itself based on the CPU board, built out of dozens of TTL chips, of the Datapoint 2200 computer. [https://www.righto.com/2023/08/datapoint-to-8086.html Source]
Despite what their naming suggest, the Intel 8008 and [[Intel 4004]] were separate projects with distinct architectures and purposes. The 8008 was not an upgrade or evolution of the 4004. The die shot of the 4004 reveals the initials FF of the chip designer, Federico Faggin. The die shot of the 8008 reveals the initials HF of the chip designer, Hal Feeney.
