The Logic Behind Pre AOS TI Calcs

[Matt Agajanian]

Well, last night, as I was investigating through the SR-51/51A manual (Thanks Jorge), I was in a maze of overwhelmed at the maze of keystroke gymnastics, the overt need to use the equals key to compute and store intermediate results. Another nuance I took note of was how the equations' entries needed to be rearranged. Yes, rearranged. So yes, while I most definitely concur, TI's pre-AOS logic was far, far away from any sense of natural entry method, RPN has always maintained a consistently natural logic system.
