KnightOS – a FOSS operating system for TI calculators written in z80 asm

Does the console report an error? The demo should work fine on any modern browser

Hey! Made an account just to reply. I used to lurk on both Omnimaga and Cemetech pretty frequently several years ago. I remember when the original OS signing keys were first factored as well as the bootloader debacle later on with newer calculators. I still check in occasionally to see what cool new hacks are going on nowadays.

Cemetech user here, although I pretty much stopped going there, as I was more into Casio calculator stuff and nowadays there's not much development activity for these. I must say I envy the large community support for the TI calcs, especially the older z80 ones, which are really really well understood and have been reverse-engineered in every way possible.

I kind of got into reverse-engineering the Casio Prizm, but eventually gave up because the SuperH is a much more complex architecture than the Z80; also, the firmware is so much bigger and not very well understood, it's hard for a beginner to dive in. That more or less explains why there's no such thing as a KnightOS for Casio calculators.

I'm part of that group that learned more about computers and programming with his calculator, than math. Which was actually a very good outcome, since in this undergrad computer engineering course, calculators are mostly forbidden, but the knowledge I got from them is quite useful :)

Fellow Omnimaga user here... I don't post on my account much though; I mainly just used it to tell some people I got Android running on my NSpire CX. From what I've noticed, however, it's a very friendly community.

CodeWalrus/Cemetech lurker here, both are pretty cool except due to some drama Cemetech doesn't really support KnightOS

You're welcome to make one :)
