Intel 8080A Microprocessor

Intel introduced its 8080A 8-bit central processing unit (CPU) microprocessor in April 1974. Generally considered as the first truly usable microprocessor, the chip ran at 2 megahertz and powered the Altair 8800 and the IMSAI 8080, two of the first Personal Computers. Housed in a 40-pin DIP package that contained 6,000 transistors, the integrated circuit could receive 8-bit instructions and perform 16-bit operations.
