C-BIOS is an open source BIOS for MSX computers.
C-BIOS is an open source BIOS for MSX computers. C-BIOS can be shipped with MSX emulators so they are usable out-of-the-box. This project aims to improve C-BIOS by fixing incompatibilities with the MSX BIOS and the development of a Disk ROM.
ELKS is a subset of the Linux kernel that runs on IBM compatible PCs from 8086 up. It is intended to get use out of obsolete old hardware, for use in embedded systems, and as an educational tool. ELKS has been moved to Github to protest SourceForge's installer adware hijacking. This does not directly affect ELKS, but it does affect many major open source projects such as Gimp and FileZilla by attempting to trick the user into installing adware in order to download these programs. I refuse to leave ELKS here with such policies in effect. If you have questions about this, please email firstname.lastname@example.org.
A rethinking of the Operating System Ecosystem.
This is the fifth or sixth generation of this idea, the big difference being that we have written some bootloader code and have started mapping out the kernel layout and structure. We have decided upon a core programming language for the kernel, and the core language for almost everything else. With a focus on isolating the MAJOR kernel features from the system itself, in what until now has remained research only instances, we hope to create a fully functioning exokerne. All code at this time will be available only via a git repository.
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

The Fecundity Project has the purpose of creating a streamlined AMD64 based Operating System. We will hopefully create a stable and secure operating environment, and to investigate orthogonal persistence.
An Accounting Software like Tally in Java
3D-Game with large geodic Maps (Globes) - include multiple Game-Genres
Adamant Space (AS) utilizes many new Technologies to realize high GameSpeed (3D-Graphic, InterActions) with highly resoluted Space/Time in a huge geodic World (Globe) and GamePlay comprises complex Interactions between GameObjects and real Players. Many GameGenres are intended to cover resp covered Aspects inside GameWorld allow to cover a Lot of different known Game-Genres like RPG RolePlayGame, RTS RealTimeStrategy, MUD MultiUserDungeon, ESG EconomySimulationGame etc. It's not about Covering GameGenres but about Covering (most basic) Features of Reality like Needs/Consume/Production/Trade as Base for Economy. Defined MileStones on RoadMap are: GEO: physical Model of Enviroment, BIO: Flora&Fauna with LifeCycle (wo Darwin), PSY: Life do AI to get their Food&Water&etc., ARCH for Constructions and Building. If that MileStone got archieved adding Features means adding GameFun and next Add is: ECO -- a real Economy of real economizing Individuals which represent real Markets.
