COBOL compiler for the PC x86-32 platform.
An open source COBOL compiler for the PC x86-32 platform. Generates GNU assembler and requires GCC to produce a binary. Supports Linux, BSD and MinGW 32 bit platforms.
FreeOS/1 is a Free, Open Source, FreeDOS based Free and Open Source Alternative OS, with open source Microsoft Windows compatibility using HXDOSExtender KernelEx,and ReactOS source code. FreeOS/1 will include new technologies and will be easy to use
My own operating system.
Currently ManuOS kernel is under development. Once kernel is complete, a good Graphical User Interface will be developed for ManuOS. ManuOS runs on IA-32, x86-64 and currently operates in protected mode. In future ManuOS is intended to run in long mode.
NedoPC SDK is a set of development cross-tools (compilers/emulators) to develop system and user software (and hardware) for some old home minicomputers and new "homebrew" hobbyist-friendly computers (including development of that kind of computers)
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.
Venom Operating System. A protected mode kernel for i386+ PC's. Designed for games and multimedia.
Unix-like operating system for the TI-89 and TI-92+ graphing calculators.
A compiler and cross-compiler for (Currently) Cobol (with Fortran being added later). It is intended to be the first self-hosted open-source Cobol Compiler, e.g. the compiler itself will be written using Cobol.
DOS emulation program for WinCE. Based on Dosbox.063,n0p's DosBox,Wall's pDosBox beta 2, mamaich compiller, Pocket Console and DOS Emulator. You may use these tools at your own risk!
An operating system written in RTL
The Controlix operating system is written in RTL and is designed to be modular, synchronous, distributed, verifiable and retargetable.
An operating system written in C & assembly.
An operating system written in C & assembly. FruityOrange uses the concept of a monolithic kernel and GRUB as bootloader for the kernel and some modules. There is still no release. If you want do try the development-version, get the Sourcecode and build by yourself!
MDF is microkernel operating system. Module architecture minimalistic design.
PeiAsm Multi-Processor Assembler/Emulator for x86 Windows. -Coded by M. Keaton (The Polyester Method)
512DevOS is a GPLed operating system that runs on 16 and 32 bit x86 compatible computers. The kernel and shell fit in 512 bytes and occupy only the first sector of a floppy disk.

API Caller is a software for extracting API functions from any executable and can be used to call them. With this tool, quality can easily be checked by calling functions and checking them if they are error-free.
Aurora OS is an operating system designed in a microkernel format for all users. The object is to develop a modular, mulitplatform, multitasking Operating System that is simple, effective, and powerful.
BASIC 7, Free Open Source Replacement for Microsoft's Visual Basic 6.0
Bistro is a type-safe, extensible operating system based on the Java platform. It consists of a virtual machine on top of a micro-kernel that implements process control, IPC, and base memory management. All drivers/programs etc. are run in the VM.
An open source assembler for the popular 68HC11 Motorola chipset. This assembler replaces the AS11 freeware assembler provided by Motorola.
PC boot package
Bootpack will be a PC boot package. Currently has an MBR bootsector ("mbr-bb") and a simple data-write tool ("putbin"). An assembler ("fas") and a partition bootsector ("pbb-fat32") are work in progress. Several pbb variants, a stage 2 loader ("ABC"), a 16 bit C compiler ("scc"), a boot-configurator ("BLA") will follow.
The CK 64-Bit Kernel Operating System
This project is a implementation of layers. Use Virtual machines & virtual adapters alike an onion! Another operating solution instead of Microsoft Windows Server operating system. It is to be used via remote controlling. The special new "Cktool32" will make it easy to handle *Ck64Krnl*.
Caracal is an IA32 operating system which, once stable, will be used to create tutorials and therefore teach others the basics of writing system software for IA32 processors.
An open source operating system for x86.
A new 64-bit RISC platform, complemented by a set of development tools, standards specifications and synthesizable VHDL implementations.
