I think it's a neat mix of novelty and practicality that a lot of people are unaware of.
I use a TI-83 Plus and ripped my ROM using TiLP and now use TilEM on my Linux machine and Graph89 (available on F-Droid) on my Android device. The hardest part was getting a hold of a TI Graph Link cable.
Setup generally depends on your calculator and which device you wish to emulate it on (Linux, Windows, MacOS, or Android).
Wabbitemu was a godsend back in my HS and college days! I used to have it on my MacBook and my android phone, so I always had a TI-84 ready to go. It’s a a shame it wasn’t available for iOS since I’d get many folks who would me ask about it but I had to tell them they couldn’t really use it because they had an iPhone. Who knows, maybe there does exist a TI emulator for iOS these days!
That's a good question. I figured there would at least be an application for jailbroken iPhones but I wasn't able to find anything outside of people recommending online calculator emulators similar to jsTIfied.
I just tried jsTIfied, boy I wish this existed back then, this is amazing!!! You’re saying I can use a TI calculator without even having to download an app? Sign me up!
