alt Hacker NewsI got an HP50g from Craigslist in high school that
- was cheaper than a TI
- had a primitive CAS system
- teachers had no idea how to put it into test mode
It carried me through AP calc BC, I would’ve gotten <4 off of my own knowledge alone

Mine was a Casio fx-something. Teachers didn't like it but it didn't let me cheat and it was just the right amount of functionality to help me with math. Carried me through Pre-Cal, Trig, Calculus and Differential Equations.

I had the same one. I thought it was pretty cool.
One perk I found is that if I kept it in RPN mode, people stopped asking to borrow my calculator, which was a valid excuse to learn how to use RPN, which is basically all I use now (and indirectly made me really love the Forth language).
