Rest in Pieces, Little TI-85

Though early reports of your demise may prove inaccurate, I'm afraid your heyday has passed, trusty calculator. You've had AAA batteries disintegrate inside you twice in about seven months. That can't be good for your insides, and it sure ain't helping the first numerical programs I wrote for you in primitive TI-BASIC. At this point, I'm holding onto you because I want to retain the fond memories I have of Dr. Singer's crypto courses more than because you actually help facilitate solving my day-to-day math problems. Sunrise, sunset.

Romberg integration. Newton's method. Fermat's Little Theorem. Rabin-Miller factorization. Euler's phi function. (Ah, Euler's phi function. My favorite.)

You will always be remembered fondly, my friend.
