Re: TI-H: EL slows my processor!?!?! WHAT!
Richard don't you know whats wrong? The clock speed for calculators is
based on the charge and discharge of a capacitor. if it charges and
discharges at a slower rate the clock rate gets slower... This is
elementry stuff... :) Ti didn't want to spend money on expensive crystals
so they used a clock method thats been here for ever... Even I can buy
crystals...
