Re: A86: Theory question [i think its about time we....]
ok i just have to jump in on this one... i haven't found a method to
actually clock my calc's mHz, but through the method i chose (just removing
the capacitor) i've heard and read in many places that it is about 3.5x
faster. 21mhz more or less. I have actually heard of someone saying they
were able to determine that it does in fact run that fast.
the point...
use rayovac renewal batteries in your calc. at the speed mine is running i
still only recharge the batteries every month or so, even then they don't
really need it, it just seems to be slightly faster when recharged.
there is not as you suggested a minimal speed increase. it is a huge speed
in crease. you especially notice this when graphing complicated functions
and also on long integrals.
