I’ve had this calculator for 35 years. My daughter is using it at school now. Still works!
Got my Ti-30, discounted as display model for $16, from a small town Sears store 49 years ago. I became so used to the key locations I couldn't use other calculators. Finally replaced it with 3 Casio SL-300SV solar calculators. Bought 3 so I wouldn't have to relearn different ones again. I still miss the functionality of Ti-30.

I still have my TI-30 somewhere, I don't know if it still works. I'll have to see if I can find it. I do see several on ebay for sale.
