Description
The Intel 8080 was the second 8-bit microprocessor designed and manufactured by Intel and was released in April 1974. It was an extended and enhanced variant of the earlier 8008 design, although without binary compatibility. The initial specified clock frequency limit was 2 MHz and with common instructions having execution times of 4,5,7,10 or 11 cycles this meant a few hundred thousand instructions per second. The 8080 has sometimes been labeled "the first truly usable microprocessor", despite the fact that earlier microprocessors were used for calculators and other applications.
