Template:mpu The 8008 (pronounced "eighty-oh-eight") was an 8-bit microprocessor designed by Intel and introduced in April of 1972. The 8008, which was part of the MCS-8, operated at 500 kHZ, had 8-bit data words, and could address 16KB of memory (14-bits PC). Originally commissioned by Datapoint Corporation (then Computer Terminal Corporation) for their Datapoint 2200, by the time the 8008 was ready it no longer met CTC's requirements. Intel retained the rights to market the chip independently.
The 8008-1 is a faster version of the 8008 operating at 300 kHz higher frequency. The chip is otherwise identical.
