The AROS Research Operating System is an effort to implement an Open Source and portable operating system that is compatible with AmigaOS(TM). Originally, it was meant as a direct reimplementation, but already has features not existing in AmigaOS.
Syllable Desktop is a complete operating system that is easy to use, powerful, lightweight and extraordinarily fast and responsive. It has its own kernel, filesystem, GUI and applications. Syllable Server is a matching small and efficient Linux server.
Written in pure ASM and Exode with cloud computing in mind.
Cloudium OS is being written in pure ASM. It's designed for speed and ease, having cloud computing in mind. It also is secure (without requiring constant user input like Windows). But, how are we going to do this? Well every os wants/says these kind of things, so to accomplish our goals we follow these simple rules: keep it simple (that's way better then these complex interfaces etc. almost nobody wants), generalize (this makes things easier and more useful without extra complexity) and be inventive (sometimes doing it the classical way just doesn't work). Note: development peace will be temporarily lowered until February the fifth. Please check out our OS and Project site!
Embedded Operating System
EXIRION/OS is an operating system for embedded computer systems. These operating systems are designed to be compact, efficient at resource usage, and reliable, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run. They are frequently also referred to as real-time operating systems, and the term RTOS is often used as a synonym for embedded operating system. EXIRION/OS project, a Open operating system for computers that can be used in specific operations that require execute a task at a time, EXIRION/OS operating system is a monolithic and mono layered task, which can be used to control complex electronic equipment without the use of instruments PLC, offering a wide range of electronic and industrial applications, EXIRION/OS is also an educational tool, it is an open source operating system to use it as an example of building operating systems in universities and technical colleges.
Alternative operating system for x86 computers
Visopsys is an alternative operating system for PC compatible computers. In development since 1997, this system is small, fast, and open source. It features a simple but functional graphical interface, pre-emptive multitasking, and virtual memory. Though it attempts to be compatible in a number of ways, Visopsys is not a clone of any other operating system. You can demo the distribution from a “live” CD/DVD or floppy disk
It is a Uruguayan Linux distribution. Can be used from floppy disks, cdroom or you can install it in your hard disk. It has been designed to be fast and effective without leaving of side the graphical aspect for the user.
A replacement firmware distribution for the 3com 3CRADSL72 a.k.a 3com wireless 11g (distributed by Ya.com) and its identical twin, the SMC7804WBRA, with an ucLinux kernel based system and associated system tools.
