Ah the Erable HP48G/X. It helped me through AP Calculus BC, SAT-I (math section), and college physics and math for an EE/CS undergrad degree.

I remember using the HP 48's overpowered IR LED and ability to share apps to get the universal remote app to turn on and off TVs in the lecture hall from quite a distance. :@)

Since this is anecdote time: I got an HP49G for the SAT Math subject test (which apparently is no longer a thing). I loved it to bits.

But I ended up putting it away – by the time I was simultaneously doing college statistics, a class on numerical methods and DEs, and few other classes, I got so frustrated with having to remember inscrutable 6-letter softmenu items that I took my first summer paycheck and blew it on a TI-89.
