Well, at least this is pretty nice to have a higher level language running on KnightOS. I'll probably check it out.

^ that's been fixed on GitHub with SirCmpwn.

By the way, http://try.knightos.org/ has been fixed ! Now you can actually try KnightOS programming in your browser without downloading anything !

Yeah, thanks to legacy mode. See Phoenix, for example, or simply the castle.

I've just installed KOS on my TI-83+, but when I press [ON], the screen becomes black and turns back white very quickly, and then nothing happens. Does anyone knows what would be the issue?

Bump,

After testing on Wabbitemu, I couldn't reproduce the bug, so I guess it's only on the hardware that it happens. Can you give some context ? Where did you download the OS, how was the file named, can you test it on an emulator to see if it causes the same errors ?

Maybe there's something in the RAM of the calculator that KnightOS doesn't expect? You can try removing a battery and reinseting it while holding the DEL key. This will ask you to install a new OS, but you can cancel this by pressing the on key. Then when you turn off your calculator and turn it back on, it should start normally with the RAM cleared (at least it does that on the official OS, I don't know if it does the same in KnightOS, but iirc it's the boot code that does this so KnightOS shouldn't affect it)

I can't promise that it'll work, but from personal experience I noticed that when programs get unstable on a calculator, a RAM clear fixes it 99% of the time.

It's not your hardware, another user had the same issue. I'm sorry, but I have no idea what it could be. One last thing though: on the TI-OS, can you press [mode], then [alpha], then [ln] and tell me what the base and boot code versions are ?

Hello again! We haven't posted any updates since November so there is a lot of news for you:

• New contributors! We now extend thanks to kedarbramhe, Hugo "s0r00t" Courtial, Francis Lewis, Noah "Ivoah" Rosamilia, Kevin Lange, altbdoor, Justin "Jnesselr" Nesselrotte, Bjorn Neergaard, Willem "willem3141" Sonke, and Andrew Boos!
• New games have been ported: ports/ztetris (thanks unlimitedbacon!) and ports/rubik (thanks Ivoah!)
  
• New software from boos1993: community/progcalc is a programming calculator app that lets you do integer math on KnightOS (thanks boos1993!)
  
• community/calendar has been added to the default distribution (thanks willem3141!)
  
• We have redesigned knightos.org to be prettier and such (thanks altbdoor!)
  
• There is a KnightOS wiki now (thanks boos1993!)
  
• Users can upgrade their OS through the settings tool without pulling a battery (thanks, SirCmpwn!)
• Lots of improvements have been made to PKO (packages.knightos.org) (thanks boos1993!)
  
• Date/time support in the kernel is nearing completion, settings has been updated to support it as well (thanks willem3141!)
• We've started working on calcsys (thanks, SirCmpwn!)
  
• Our new assembler/linker, scas, is nearing completion. It will be released as independent software when it matures. (thanks, lots of people!)
• The castle is maturing, and now lists app manifests from /var/applications/ so you can run any installed app. We've also made /var/castle/pin-{0-9} symbolic links to app manifests, which defines the apps pinned to the home screen. (thanks, SirCmpwn!)
• We have partially implemented the KIMG format and produced a tool to convert most image formats into KIMG files. (thanks, neersighted!)
• We have started work on a text editor called "bed" - Basic EDitor. (thanks, lots of people!)

Pretty pictures:

This time around, I'm pretty sure most of the work was NOT done by me, which is a first Thanks everyone!
