KnightOS VS Tiny C Compiler

It looks like your calculator is running KnightOS, a custom operating system for TI z80 calculators. If you no longer want to use it, you can reinstall TI-OS. I suggest looking at the KnightOS website for further instructions: https://knightos.org/. Source: 11 months ago

The creator also made https://knightos.org, written in z80 asm. Source: almost 2 years ago

Well, whilst it can't quite play Skyrim, because the TI is built around a z80, you can have a full operating system is you'd like. Source: over 2 years ago

There are a very few calculators that you can do this to. See https://knightos.org. Source: over 2 years ago

There is Knight os which might be what you're looking for. It does have lackluster support for math functions but is great for homebrew games. They have detailed install instructions and allow you to revert back to the official os if needed. https://knightos.org/. Source: over 2 years ago

For what it's worth you can implement a C compiler in under 10kLOC. The chibi C compiler is only a few thousand lines [1]. There is also Cake [2] and the tiny C compiler [3] which are both relatively small. [1] https://github.com/rui314/chibicc [3] https://bellard.org/tcc/. - Source: Hacker News / about 2 months ago

I was going to say, the list should include something by Fabrice Bellard. Tiny C Compiler is one. https://bellard.org/tcc/ I was thinking, maybe first version/commit of QEMU would be interesting to read. - Source: Hacker News / 9 months ago

I occasionally use tcc (https://bellard.org/tcc/) like an interpreter (`tcc -run`), it's convenient for certain odd tasks. Not so much for interactive stuff, but if I'm building little PoCs for an idea that will get dropped into a C project, or fiddling with structs work out how something should/is being stored, or in situations where I'm making stuff that interacts with or examples based on C code and I want to... - Source: Hacker News / 11 months ago

This reminded me the idea of compilers bootstrapping (https://news.ycombinator.com/item?id=35714194). That is, now you can code in SectorC some slightly more advanced version of C capable of compiling TCC (https://bellard.org/tcc/), and then with TCC you can go forward to GCC and so on. - Source: Hacker News / 12 months ago

The tinyc compiler reads scripts like a c-interpreter, with shebang and all. Source: about 1 year ago
