Most likely ASM or C. C wouldn't be surprising, considering how unoptimized some stuff are, but an OS could be coded in ASM or C depending of your preferences. AHelper0 was using SDCC for his GlassOS project.

I would definitively not recommend making an OS unless you have 2 years of ASM/C knowledge, though. There is a reason why almost all third-party OSes have failed to be completed.

Definitely Asm. The OS doesn't look anything like something coded in C.

@Hayleia this question applies to literally every model you mentioned, as well as all 83+ models. Kind of a moot point.

That had nothing to do with this topic at all though. His question was about the operating system, which is the same language across all models.

On the other hand, let's not go to the same extent as certain people in the community did before and making newcomers feel like they committed an heinous crime when they forget to add a + at the end of 84+, call the Silver Edition SE or misspell Nspire as nSpire. Not that it was extreme, but it's like on those forums where on your first post ever you got yelled at by grammar nazis for one little spelling mistake in a seven paragraph long post or for other insignifiant mistakes.

Besides, as much as I prefer people to name their calculators properly to avoid confusion, TI really didn't help the matter much with their inconsistent model names (especially the 82 Stats and Pocket models), although on a marketing point of view, I guess they made sense, since the TI-83 Plus was extremely popular.

Yeah I was mentionning C because back then, there were some community members doubting that TI used ASM for the OS and that they might have used C instead or some other higher level language. It was because of the possibility that the team probably wanted to use something more mainstream or due to how terrible the source code was.

I just ment the TI-84+

ITS MEANT YOU IDIOT!!!!111!!11one
