Fiwix
A UNIX-like kernel for the i386 architecture
FiwixOS 3 is a Fiwix distribution, an operating system made from a software collection that is based upon the Fiwix kernel. It basically comprises a Fiwix kernel, GNU tools, libraries and additional software. All the included software is free and open-source software made available both as compiled binaries and in source code form, which allows modifications to the original software. FiwixOS 3 uses the Newlib v3.1.0 as its C standard library, and the Ext2 as its primary file... -

Aquila OS
AquilaOS: UNIX-like Operating System
Aquila is a minimalist operating system kernel written in C++ from scratch, aiming to offer a clean and understandable implementation of low-level OS concepts. Designed for x86_64 systems, Aquila includes its own bootloader and supports protected mode operations. It features a modular architecture with components for memory management, interrupts, and basic task scheduling. As a learning tool or hobby OS project, Aquila focuses on clarity, with an emphasis on educational documentation and... -

FlingOS
An educational operating system written in C#
FlingOS is an educational operating system and framework aimed at teaching students and developers how operating systems work, using C# and a bit of C++ and assembly. It allows developers to build kernels in a managed, high-level language and understand the entire bootstrapping and runtime process from scratch. FlingOS is particularly focused on making OS development more accessible by bridging the gap between high-level languages and low-level hardware programming. -

qtOS
Tiny operating system for running HCFSM-based systems
...Each task is activated either to be run in parallel (fork) with other active processes in the system or subordinated to the caller task, thus blocking it and creating a hierarchy of tasks. Execution of processes can be preemptive or non-preemptive and, among those with the same priority, a round-robin turn is performed. This operating system can be used to illustrate these concepts and can also be used to suport the execution of some embedded systems. -

Avark
Avark is an embedded operating system for AVR microcontrollers.
...It is currently being developed for the AVR architecture. Main Objectives of the Avark operating system is to facilitate multitasking. Currently a round robin scheduler is being employed, but soon a priority based preemptive scheduler will be developed. Resource guarding of various CPU peripherals will be implemented using device drivers for the peripherals and semaphores. Do send me feedback at my email id. amol.1991@gmail.com Does it work? Is it insanely useless? -
