As you may know, Knight Kernel is an in-progress open-source kernel supporting the TI-73, TI-83+, TI-83+ SE, TI-84+, and TI-84+ SE calculators.  However, it follows a rigid standard that closely coincides with KnightOS.  To offer a better solution to OS developers who want to make an OS, but don't need all of the features associated with Knight Kernel, Asm OS is offered.  Asm OS is a very basic operating system that offers very little to the user.  It comes with plenty of routines and helper code, and handles all of the hardware initialization.  Asm OS will initialize hardware and send the user into an infinite loop, which it is your job to replace with an operating system.

Asm OS is a great starting point for people who want to learn how to write their own operating system, without having to try and figure out the complex source code of KnightOS or Knight Kernel.

Thanks!  Making an OS would be so much easier since the hardware initialization routines are in one place. 
I've always wanted to make rst routines...

You really wanted a new calc OS to be written in TI-BASIC?

Is that even possible?

Is that even possible?

No, as TI-BASIC is an interpreted language, and OSs have to be bytecode. Also, even if you were to write a TI-BASIC compiler, the language does not have the control necessary for an OS.
