The fact that you can and should enter a sequence of buttons to get a QR code to verify if your casio is in fact a casio is wild
I got a V200, the successor of ti92. Best device ever, so much power in that brick. I never found something equivalent on computer, except maybe wolfram alpha.
I’m just sad I never had to really use it in my work. Only time it could have been useful, it was dead 😥.
There are emulators of a lot of old calculators online. Is this one yours?
Yep, that one. But if you don’t use it everyday, you quickly forgot how it works ;)
I have a 991es but I only got it in uni because it was the only one allowed. Before that I had a TI 30X IIS. Loved that Casio. The new one looks like a pain in the ass to use.
