It is interesting to note that a 30-06 rifle bullet travels at 2800
ft/sec. which means that it takes 3.5E-4 seconds to travel one foot. The
minimum number of Mhz required for a CPU to go faster than a speeding
bullet would be (1 insturction)/(3.5E-4 sec.) or 2857 insturctions per
second. Asuming a 32 bit instruction that means that a minimum of .92Mhz
(thats right .92 not 92) to go faster than a speeding bullet. All of
this to say Big Deal our clacs can alrredy do that. Assuming 6Mhz and an
8 bit instucrtion the calc can preform 262 caculations in the time it
takes a speeding bullet to travel one foot. If it were a 32bit machine
it could do 66 calculations in that same amount of time.
