OK, Time to resolve this matter. "Turbo"-ing your calculator does *NOT*
increase battery usage significantly!
The "Turbo-TI" modification simply speeds up the internal R/C circuit that
produces clock pulses for the CPU. The pulses happen faster, the
processor runs faster, but there is VERY LITTLE CHANGE in current draw.
This is basic electronics, folks. A calculator is not analogous to an
athelete, and each clock pulse does not draw a specific amount of power
out of the batteries (power is drawn regardless of what speed the clock is
running at).
Now, I hope this puts this silliness to rest.
The "Turbo-TI" modification DOES void your warranty, however.
