The number of clock cycles does not proportionally relate to the number of
calculations. What do they mean by an "instruction"? What type of instruc-
tion?  What complexity and cost does it have ? How many bits does it have,
thus how expressive is it?

If  it were a 100 MHz computer that's most powerful, you would possibly be
looking at the early 80's or late 70's?? For home computing, 100 MHz prob-
ably came about with the Pentiums in the early 90's, maybe 1992.
