TI-66 double speed mod

Odd how EE and ME can follow the same paths. The resistor experimentation reminds me again of high school and advancing the timing of my Datsun 240Z sports car. Too far and it sputters and misses ignition. Back a bit and ZOOM! The Goldilocks syndrome - it has to be tuned just right - and then a touch more on the conservative side to allow for other variables (temp/humidity/air density/etc.) All fun stuff! And although I like the calculator, I'm not too worried about damaging it - a whopping $29 on ebay. IIRC, my 59 cost ten times that, back in 1978 no less.
