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.
Software development for 4Mb portable, using Z80 CPU and AA batteries
This project is for the portable computer "Cambridge Z88", produced by Sir Clive Sinclair (of ZX Spectrum fame).
We continue to support software development (ROM, 3rd party apps on memory cards and desktop applications).
We have moved to https://cambridgez88.jira.com/wiki (development, source code and documentation).
However, we continue to publish files for download here.
UNIX/LINUX and legal homebrew software on the xbox360 gaming console
An effort towards porting Linux and related open source operating systems to the Xbox 360. Another goal is to write homebrew applications with a legal and free Software Development Kit consisting of the Library (LibXenon) and the appropriate cross-compiler toolchain (Xenon-Toolchain).
You can get informations and Source-Code on the following Pages:

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.
OCP - Open Controller Platform is software platform that makes it easy to build a cross-compilation toolchain with Ccompiler, assembler, emulator and programming tools for embedded micro corntroller systems.
Embeddedable Forth compiler is a Forth system for 32 bit devices with no OS. I am currently using it with ADUC7026 board. Also tested on STM32. Win32 version is is used for testing.
LoseThos, a free, 64-bit, multicore, PC operating system designed from scratch -- not a Unix. No bloat. Boots in 2 seconds. Comes with games, Ccompiler, tools and lots of demos of the API! Test-drive or install -- it is a live CD.
Project-Sparroh is a hobby operating system project. Goal is to write an OS from scratch for the purposes of learning how they work and for fun. An assembler and high level language cross-compiler will also be written first and used to build the OS.
Put idle assets to work with competitive interest rates, borrow without selling, and trade with precision. All in one platform.
Geographic restrictions, eligibility, and terms apply.
Open Embedded Real Time Operating System. Widely and graphically configurable from a very small non-preemtive OS up to a fully featured pre-emptive system. First target is to cover 8-bit AVR microncotroller's family with GCC - AVR compiler.
K-OS is an open-source realtime-operating-system based on the OSEK/VDX standard aimed at compiler and microcontroller independence. Currently we support Motorola (Freescale) HC12/HCS12/HCS12X targets.
PRE-ALPHA! Eventually, it will become a minimal but fully ISO 9899:1989 / 1999 compliant C standard library framework in the Public Domain, with clean OS interfaces, as a starting point for OS / compiler development. PRE-ALPHA!
The Thix Operating System is fully functional at this time. Many free software packages have been succesfully compiled/run under it, including development tools such as the GNU C/C++ Compiler suite. -- VISIT www.thix.eu
Javum, the Java Virtual Unix Machine, is an ambitious project which aims to provide a full virtualized Unix environment including Ccompiler (GCC), Unix-like API, shell, and command line tools, inside of a JVM. Details @ http://javum.wiki.sourceforge.net
MEDDAC is the seeding point for designing a new approach to Operating System design itself. It is an Open Source project with roots in mainframe design and development the author began in 1979. Monitor Editor Disassembler Decompiler Assembler Compiler
Eclipse OS is a C++ kernel that I am starting as a summer project. Right now it is fully bootable and can accept input from the keyboard. It can also do simple tasks like detect how much RAM a computer has, or tell time. I am hoping to port C++ compiler.
SDL REFLEX is the micro kernel of a real time operating system for the AVR microcontroller family. The kernel is especially designed to implement systems described in SDL The Specification and Description Language . Compiler GNU ANSI-C for AVR v.3.3
This is a library library for the handyboard (www.handyboard.com for a description), which can be used with the gcc m68hc11 compiler. The library has a somewhat different feature set from Interactive C but should be much faster.
We intend to provide a development system for the Rabbit2000/3000
microcontrollers.
On Linux: a cross C-compiler, assembler, linker chain.
On the rabbit: a BIOS including download and debugging
facilities. Later a realtime kernel + TCP/IP stack
QuickOS is a really-quick-realtime-multitasking-os, that requires less than a second to boot up. Basic-kernel-functions will be written with NASM assembler. We should get a C/C++ compiler to work for us.
