PPS-4 (10660) - Rockwell International
Template:mpu The PPS-4 (also known by its part number 10660) was a 4-bit microprocessor designed by Rockwell International and first produced at the 3rd quarter of 1972, making it one of the earliest commercially available microprocessors. The PPS-4 is part of the PPS-4 Family.
It appears that in 1975-6 Rockwell might have renamed the 10660 to 12660 after introducing the PPS-4/2. It's not exactly clear if any actual changes were done to the die itself, but its entirely possible.
