An operating system based on the best Windows NT design principles
ReactOS is an open source effort to develop a quality operating system that is compatible with applications and drivers written for the Microsoft Windows NT family of operating systems (NT4, 2000, XP, 2003).
JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.
Collection of all opensource software used on TomTom's GO devices
A fork of ReactOS which aims to be compatible to the NT architecture (but not a clone) meeting WINE's standards every time a part of NT interface is implemented. The fork was done at revision 9494 before ReactOS changed slowly into Tinykrnl.
Real VMX is a VxWorks like operating system kernel released under LGPL. It should support multiple hardware architectures, only i386 support now. Help wanted with ports to other architectures. Development is done on Linux with the GNU gcc compiler.
Clicker is a project for a Multitasking Open-source operating system written from scratch. based on a modular micro kernel. We want to explore new way of designing and using OSes :) [newz: PCI, NE2K and VBE]
Unix-like operating system for the TI-89 and TI-92+ graphing calculators.
Small real time operating system for AVR and ARM microcontrollers
AvRtos is a small, preemtive, priority based real time operating system for Atmel AVR and ARM microcontrollers. It was written in C. AvRtos provides message queues and semaphores for task synchronization. It uses a static memory allocation scheme. AvRtos is nearly the smallest RTOS out there. Even pico]OS is much bigger. AvRtos can be compiled using gcc compiler. There is a AvrStudio 4 and Eclipse project file to get the example code working very quickly.
CMAKE build enviroment for LPC2000 and LPC17xx Cortex MCUs
The goal of project is to build CMSIS like environment for LPC2000 series MCU and to write RTOS for LPC2000 and Cortex Microcontrollers
A Small, Reliable, Compact, Object-Oriented, Portable RTOS(Real-time operating system).
This project provides a small kernel for the micro controler PIC18F4550 using the SDCC. Since the kernel is intended for small devices, the scope of the project is to provide a minimal process management and process communication support.
A pre-emptive operating system for Atmel AVR 8-bit microcontrollers featuring queues, semaphores, a flash fileystem and high level peripheral device drivers.
A new advanced customizable graphic menu multi boot and OS loader based on XOSL project with gujin project features, this project integrate too a mini OS to provide certain customizable specialized maintenance tasks before boot partition/load OS target.
CJet eXTreme OS is a new project to develop a cross platform operating system with a native application interface designed to make it easy to develop for several architectures at once.
CakeOS is a hobby operating system started by Lukem_95. It is written in C with some partial ASM coding. Cake is a modern OS with portable functions and drivers. We are looking to keep a fairly small team size for this project.
CapROS is an experimental capability-based operating system, based on EROS, KeyKOS, and Gnosis. Ports exist for the Intel IA-32 and ARM9 architectures.
An open source operating system for x86.
Codename Five is an operating system kernel, written as an experiment in learning assembler, written from scratch for x86. It is not (purposely) based on any previous operating system.
CrazySoft OS - is a OS writed in Assembler language
Gebix is a FreeBSD-based operating system that will be available for both x86 and ARM as of version 0.7 Release Candidate 1. It will sacrifice most of the legacy support to transition to new or recent alternatives.
Hydrogen Operating System is a portable kernel framework whose components are ELF objects linked to a core providing thread scheduling and memory management in a single addressing space.
The Isis OS Project Is a Controlled Project to Develop An Advanced Modern Operating System!
Jeko è un sistema operativo italiano che cercherà di mantenere un altissima compatibilità con i programmi unix, così da poter subito diventare un OS usabile. I suoi obiettivi sono quelli di velocità, leggerezza, semplicità, supporto di molti device
MatriX OS Kernel is a general-purpose OS kernel, providing flexible deployment with modules. It is designed to be integrated into various runtime environments, e.g. embedded equipments, realtime systems, desktop systems, and server systems.
MenuetOS is a fully 32 bit assembly written graphical operating system. Menuet supports 32 bit x86 assembly programming as a faster and smaller system footprint. Menuet has no unix roots and the basic system is meant to be a clean asm based structure.
