Open Source Windows Operating System Kernels

DOS/32 Advanced DOS Extender is a drop-in replacement for the DOS/4GW DOS Extender and compatibles. Being fast, small and flexible DOS/32A can be used in many environments, from embedded systems to DOS emulators, by both developers and end users alike.

colorForth is, in Chuck Moore's own words: "A dialect of Forth that uses color to replace punctuation. Includes its own operating system. Produces extremely compact programs. Instant compile from pre-parsed source."

A Java 2 (JDK 1.3/1.4) compatible virtual machine. joeq is unique in that it is almost entirely implemented in Java, making it reliable and efficient. It is also language-independent, so code from any language can be seamlessly and dynamically compiled.

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.

amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.

several vaguely related projects worked on by me: a 3d engine with a javascript-like scripting language (pdsys); an older scheme dialect (vmsys); ... (2009-04-28: I have been gone for years, may try to put up some newer stuff...).

The Simply Memory Manager (SMM) is a replacement for the native memory manager for Free Pascal and Lazarus projects on Windows. Download SMM at https://opensimply.org/smm Free Pascal's native memory manager uses certain memory allocation and deallocation functions for 32-bit Windows applications that cause fatal errors when reusing large amounts of memory repeatedly, and it runs in this case rather slowly. SMM prevents such errors by using a different approach, and it is much faster on avalanche-like memory allocation requests. Simply Memory Manager is a part of the OpenSIMPLY project: https://opensimply.org/

This project aims to develop a Lisp based operating system for general purpose computer architectures.

This project was previously oriented towards creating an AI based Operating System. However new visitors should refer to www.theasciiproject.com for information about what this project has developed into.

fast single-privilege single-address-space preemptive-multithreading persistent data-centric secure multiuser operating system with safe-language and reconfigurable graphical interface

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.

IMA2 Simple command-line editor of binary files (images, object filers, byte code, etc). More sofisticated that F4 option in FAR. More simple that GUI hex editors. Can be useed as command-line utility in scripts.

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.

16 bit Forth for PC. No OS required.

The CodeTime platform covers every aspect of parallel software from authoring, through distribution, to run-time. Its goals are: high programmer productivity; write once, run high performance anywhere; and wide acceptance.

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

The MyNOS project aims at developing a new and different operating system, based on high-level languages. MyNOS will be based on the OCaml bytecode interpreter. We'd like to explore microkernel architecture and new language definition too.

- Plattform: amd64 and nvidia GeForce with shaders - Goal: Assembler with object-orientated paradigma with the ability of massive parallel calculation - Has its own bootloader and its own rudimentary os with a ncurse like editor

This project aims to do for MULTICS what Linux and GNU have done for UNIX - that is, to produce a totally free, totally unencumbered, and totally compliant OS that learns from prior work, rather than copies it.

OS based on Agent based Security with a new type of split kernel and agents platform.

Silis OS is a online based operating system which will allow users to access their files and programs from any where in the world.

The SuperWikia Alpha 1.0 application is an IDE specifically developed for 3D and graphic content. Its built upon the Unity foundation and incorporates various libraries from Komodo IDE, wxDevC++, CodeBlocks, QT Creator and other applications. Its Realtime purpose is an IDE (codesmith developer access), its Runtime (U/I) function is as a space building simulator, operating in conjunction with the SuperWikia 'Navigator' user interface to simulate space economics and fleet operations. It allows users (known as 'data fleet navigators' or DFN's) to compete in tourneys over vast regions known as 'expanses' and to create envoys that manage onsite and offsite stations. Using additional SuperWikia components, users may enhance their experience with plugins and 'dataplates' that help build the Runtime environment. Codesmiths (SuperWikia Alpha developers) can also build on top of the codebase using 'transcribes', acronym/algebraic encodes that differentiate codesmith works.

OS for embedded and mobile devices based on tiny byte-code interpreter and FORTH language compiler (into platform-independent byte-code). In other word its smallest programming language realization works on any type computer with any OS
