Introduction to ISOS

I am writing to let you know that I have created a derivative work from JaysOS, the ‘Toy OS’ for Gameboy advance of which you have talked here. It is called ISOS and runs on ARM’s Evaluator-7T evaluation boards which feature the same processor has the Gameboy Advance.This board doesn’t have a screen (just a few LEDs and a 7-segment display), thus, the graphical part of the system has been removed and emphasize have been put on multi-threading and memory management.

My objective is to have a simple package that can be downloaded and that allows to simply write the code for the different threads of an application and then being able to easily run them on the board with the multi-threaded environment provided by ISOS.
