Free operating system for Atari computers, and more.
EmuTOS is a TOS compatible operating system for Atari ST series computers, and more. It is made from Digital Research's GPLed original sources and is a free and open source alternative to Atari proprietary ROMs.
The future of information technology will be based on controlling the flow of natural light. This project is an attempt to establish the code (or software) that will enable this to happen. It involves rewriting an OS from the ground up.
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.
Open Source microkernel for ia32 architecture. Basicly this is a full functional operating system implementation using GNU C and nasm. Fully commented in spanish and with external documents explaining system calls, library functions, design, etc.
The Patagonia OS is intended to work with x86 computers. It is for general purposes and can be modified easily and add drivers for other devices. The main idea of this kernel is transform PCs into research machines.
