Wspólny projekt społeczności OSDev.pl
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.1 weekly downloads
OpenMAC is a TinyOS-based implementation of IEEE 802.15.4 MAC layer, which lies at the core of MeshNetics ZigBee stack, and provides basic wireless networking (star,peer to peer) to WSN's. Available for low-power ZigBit modules and Atmel AVR Z-Link Kits3 weekly downloads
OnyxOS is a 32 bit protected mode operating written primarily in C with a small amount of ASM. It aims to be a small OS useful for learning low-level OS development and provides a base for other hobby OSes to grow from. It features a shell called Slosh.
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.
mmOS(my mini Operating System) is a simple but full function operating system kernel. Major purpose of mmOS is for studying OS principle and implementation.
