ChibiOS/RT is a free and efficient RTOS designed for deeply embedded applications. It offers a comprehensive set of kernel primitives and supports many architectures: ARM7, Cortex-M0, Cortex-M3, Cortex-M4, PowerPC e200z, STM8, AVR, MSP430, ColdFire, H8S, x86.
Real-time, modular, microkernel-based operating system under development for i386. The first goal is to support 32-bit DOS protected mode applications made with DJGPP as well as native applications.
This project is an effort to develop open source software for all old platforms, like MSX, Commodore, AMIGA, Atari, ..... and collect technical information about old platforms, keeping the "old skool" flame alive.
An operating system written in C & assembly.
An operating system written in C & assembly. FruityOrange uses the concept of a monolithic kernel and GRUB as bootloader for the kernel and some modules. There is still no release. If you want do try the development-version, get the Sourcecode and build by yourself!
An open hardware and software platform, Octobits attempts to recreate the aesthetics of the early eight-bit computer age using cheap, powerful, and readily available modern components.
An 8-bit retro computer (but faster and with much better graphics) which harkens back to “proper” machine code programming when you could hit the metal.
