Recently I started entertaining myself with the TI-Basic they(Ti) are offering, since my other programs are at home (and I need to get them). That’s made better when there are these expensive(and good) calculators just hanging around here for the wrong reasons.
It also give me something to do during evening study (when I am not supposed to have a laptop unknown to my academic dean)
It’s for the Ti-84 Colored Edition but most of them work for Ti-84 Plus / Ti-83 as well.
In case one may wonder why is that all about, I might be able to write some programs that … nevermind.
You don’t have much of a hardware control, however. So no “stripping away calculator and make it arduboy” thing.
Plus, it’s just too expensive to be a arduboy clone anyway.
