eGIS - (Ege Embedded Operating System) is a portable, configurable, extensible object oriented and real-time embedded operating system microkernel written mostly in C++ language and designed using modern software approaches using design patterns.
EternalNGE is a cross-platform software framework for developing emulators/simulators providing generic interfaces for graphics, sound, etc. The primary focus is on game-consoles though the design allows for any device using i2c, memory mapped io, etc.
Pistrix (lat. Shark) is a Open Source project of Operation System, written on Assembly and C Languages. The OS model is microkernel, because the basic task of the Pistrix is Speed and Small Size.
CDK4NIOS stands for Cross Development Kit for Altera's soft core processor NIOS and should you support with a comprehensive Assembler and C/C++ development environment under Linux. It will present only free of fee tools, so you can use it without risks.

Flavor and Thor bring you a new project based on the hard work of Judge_ on MHE (Multiple Handheld Emulator). RACE! (Rather A Cardfighter Emulator) for the GP32, GP2X, Gizmondo, DreamCast, and PC. Neo Geo Pocket Color emulation has never looked so good!
SaturnOS is an operating system designed to be run on slow computers at high speed. With the ability to fit on a single floppy disk, SaturnOS will be massively portable with on-the-fly decompression and RAM disk technology.
With this project I intend to write a really, really simple OS, just for fun and learning. I think I will never have a really usable version, as I said, that's no my objective.
uDOS is a free operating system built on the FreeDOS kernel with DJGPP. uDOS provides an integrated suite of features inluding Perl, Python, etc., as well as a Watt-32 based networking environment and ELF library support. Can be run live from CD image.
This project is aimed at making a generic hard disk manager which can work on any type of hard disk irrespective of its company and make. It should provide all the basic functions of a DM like low level format, zero fill etc.
Calcsys is a system tool for the TI-73, TI-83 Plus, and TI-84 Plus calculators. It provides developers with: Hex Editor, Disassembler, I/O Port Monitor, System Flag Editor, Console, VAT Viewer/Editor, and more.
Vera is the true calc lover's OS. The main idea behind it is that it consists of a very basic kernel that allows for file storage and some hardware control, on top of which other programs or plugins can be built.
DPM explores technologies to improve power management, with a focus on techniques applicable to running systems, adjusting power parameters on-the-fly in order to
save power during brief idle periods or execution of tasks
with lower power demands.
