The Scratch Kernel (or TSK for short.) is the most advanced OS in Scratch today. It's a lot like the Linux Kernel, it's open source, anybody can develop for, or implent it into their OS. It's a terminal based-system with a whole lot of cool features, such as the File System and the Easy User Interface that comes with the system as well!

Features:
An easy to use Terminal Interface much like MS-DOS and Linux.
A very advanced File System, create all the files you want, there's not limit!
It's open source, you can build your own Programs, or even implent it into your own OS!
Comes with the TSK-EUIE, a very easy to use OS that comes with the system!
Easy to implent into your OS, with our simple GUI Mode, that allows you to have a GUI Interface, with the Kernel running at the same time in the Background!
