@VintageProject @f4grx Oh! I have those two, too. And a TI-89 among others. But when *I* was in school I was allowed to use the back then brand new, world‘s first graphing calculator, the #Casio fx-7000G! Still have it, still works fine. It‘s in the image on the left. The other two Casio graphing #Calculators I bought just recently 2nd hand. #InternationalCalculatorDay
