HP LED - any, all, multiples (successful!) 2. HP LCD - the "more interesting ones" (RPN, RPL - partially successful!) 3. Other LED programmables - but not TI (see below) 4. Other LED scientifics - particularly, but not exclusively, RPN 5. Other interesting LEDs (like Heath 1401 - 3x of those!) 6. TI programmables (58, 59...) Had to share my latest find - in category 3 - a PERFECT, AS NEW Litronix 2290 LED Programmable! This beauty has a large LED display, with "digit for DP" like the HP Classics, square root (divide/+ !!), one memory - and - 10 KEYSTROKE PROGRAMMABILITY!! Almost useless! But SO beautiful!!!

I wondered how Victor T. Toth implemented the Gamma function with this. Quote:Almost useless! At least you can calculate the amount of time it takes for an object to fall from a given height: Code: C/ON L += += ÷ RM ÷ += S Quote:But SO beautiful!!! Nice find. Congratulations! RE: My 10 Step Program - markhen - 08-10-2018 04:46 PM I read Victor's page and that is what caused me to have an auction site search active! Victor's program makes use of that "hidden" square root feature (divide followed by +=), nice. Strangely Victor's text answer of 4.67 seconds does not agree with the program or the equation - which yield 4.52 seconds ;-) RE: My 10 Step Program - Thomas Klemm - 08-10-2018 05:13 PM (08-10-2018 04:46 PM)markhen Wrote:  Strangely Victor's text answer of 4.67 seconds does not agree with the program or the equation - which yield 4.52 seconds ;-) I assume he made a typo and used $$9.18\frac{m}{s^2}$$ instead of $$9.81\frac{m}{s^2}$$ for the gravitational acceleration g. Cheers Thomas RE: My 10 Step Program - Eddie W. Shore - 08-12-2018 02:11 AM 10 steps? Wow! The calculator sure does look nice.
