I got this calculator in high school back in 19something… a long time ago. I used it in calculus, college physics, statistics, last semester’s chemistry class… it was the calculator I grew up on.
A few weeks ago, some of the buttons on the fold-out section stopped working. It’s very sad but calculator microsurgery isn’t a priority.
