The iSeries is the culmination of a series of midrange computers, starting with the System/3, which was engineered in the late 1960s. Based on this 1960s engineering, what is the maximum number of bits per instruction that can theoretically be processed by the CPU on this series of systems?
a. 32 bits
b. 64 bits
c. 128 bits
d. 256 bits

Answer: c, 128 bits. The original architecture for the System/3 was to allow for 128-bit processors even though such processors did not exist nor were they contemplated in the late 1960s.
