- MIT Exokernel OS - http://www.pdos.lcs.mit.edu/exo.html
Puts applications in control, runs 10x or more faster. Exopc and XOK versions run on x86 PCs. ExOS library gives user-level extensible implementation of Unix OS, so most applications compile and run with no change. Download. [Open Source, MIT]
- miray Software - http://www.miray.de/home/
Makes µnOS: 72k microkernel on 8k nanokernel client/server architecture based on OOP framework, symmetric multithreading, multitasking, priority based scheduling, fully interruptible, separated address spaces, and full memory protection. Free download.
- Unununium Operating Engine - http://uuu.sourceforge.net/
Claimed as radical new approach to OSs: no-kernel, self-modifying cells (like objects); single address space, useful where memory and CPU power is low, and maybe for AI. Written in self-modifying, modular assembly language. [Open Source, BSD]
- Miranda - http://miranda-os.sourceforge.net/
Planed features: Exokernel architecture, object-oriented, POSIX compliant, intuitive GUI, and best technologies: journaled main filesystems, LibOS modular library. Development documentation. [Open Source, LGPL]
- Miranda: SourceForge - http://sourceforge.net/projects/miranda-os/
Downloads, announcements, and a forum. Programming languages: Assembly, C, and C++.
- dr'ex - http://drex.sourceforge.net/
Exokernel written in C/asm for the x86 architecture. Released under GPL.
- dr'ex: SourceForge - http://sourceforge.net/projects/drex/
Information, news, forum, CVS, downloads. [Open Source, GPL]
- Elysium - http://elysium.sourceforge.net/
Main idea: enforce no abstractions, rather, have them as options, to all levels of system: hardware, kernel and file services, ways users interact with system; based on exo principles. Descriptions, news. [Open Source]
- TUNES Project: No-Kernel - http://cliki.tunes.org/No-Kernel
Unique description of operating systems without kernels, links.
