Open Source Assembly System Software for Mac

Info-ZIP portable compression/archiver utilities (Zip, UnZip, WiZ, etc.)

Project has moved to https://github.com/CloverHackyColor/CloverBootloader.

FLAC is a free lossless compressed audio format which supports streaming and archival. The FLAC project maintains the format and provides a reference encoder/decoder and input plugins for several popular audio players.

This project has been moved to http://pros.cs.purdue.edu/ PROS is a lightweight and fast alternative operating system for the VEX Cortex Microcontroller. It features multitasking, low-level control, and Wiring compatible functions to harness the full power of the Cortex. With a real-time kernel based on FreeRTOS and a development environment built on Eclipse CDT, PROS uses proven software to increase the reliability and usability of the VEX development system across all three major computing platforms. PROS is currently under active development to make it usable for VEX high school and middle school teams. PROS is intended for advanced VEX users seeking to move beyond competing environments. Eclipse and FreeRTOS have their own licensing agreements. Please see http://www.eclipse.org/legal/epl-v10.html and http://www.freertos.org/a00114.html for details.

HelenOS is a portable microkernel-based multiserver operating system written from scratch. It decomposes key operating system functionality such as file systems, networking, device drivers and graphical user interface into a collection of fine-grained user space components that interact with each other via message passing. A failure or crash of one component does not directly harm others. HelenOS is therefore flexible, modular, extensible, fault tolerant and easy to understand. HelenOS does not aim to be a clone of any existing operating system and trades compatibility with legacy APIs for cleaner design. Most of HelenOS components have been made to order specifically for HelenOS so that its essential parts can stay free of adaptation layers, glue code, franken-components and the maintenance burden incurred by them.

The aim of our project is to create a portable microkernel and a set of OS services that allow good local performance, multiple concurrent operative system personalities (ie UNIX and a native interface) and easy integration of distributed components.

MikeOS is a an open source 16-bit operating system for x86 PCs, written in assembly language, which boots from a floppy disk or CD-ROM. It is designed as a learning tool for x86 assembler and basic OS design.

x86Lib is a x86 CPU emulation Library. It is meant to help those that want to create their own emulator. Note: This is not a PC emulator right out of the box. This is meant to aid emulator developers.

Soft-realtime operating system, based in a microkernel design and providing QoS and persistence capabilities.

CubTrix is a graphical user interface with support for real-time applications. Built on top of a small, fast and efficient real-time microkernel.

Project name: frecl (free remote control). This project is devoted to a problem of remote controlling PC. (For an example: management of several IR-remote controls of the several computers incorporated into a network, using one or more IR-receivers.).

The Hierarchical Loadable Schedulers (HLS) framework is a scheduling infrastructure for hierarchically composing soft real-time schedulers. Each scheduler only communicates with other schedulers and the HLS infrastructure according to a well defined i

HALT is a developer friendly programming and simulation environment for the Motorola 680x0 family of processors. Targeted at academia, it is centered around ease of use and utility.

A Unix-like (Not compleatly Unix-compatible) Kernel. Right now, we have (very limited support) of 80486+ IBM-PC AT compatibles. Written in C, and assembly. No network support planned for the forseeable future.

Minerva's primary goal is security. To allow all users to feel safe and secure but have the freedom to do what ever they want. We also want a fast easy way to bring every linux and windows o/s together.

MITE HAS MOVED TO GITHUB! Mite is a simple general-purpose VM system that provides fast JIT translation to good native code, and safe interpretation. It is easy to target (the core specification is about 10 pages), and simple to implement (a few thousand lines of ISO C).

NewOS - Yet another operating system.

OpenFSL is an os-independent file system library. It provides file system control with customizable disk control. Currently supports MBR and FAT32 partially.

PenCube, the ONLY kernel for otakus.

Unix-like operating system for the TI-89 and TI-92+ graphing calculators.

chaos is a new operating system - written from scratch by a young group of people. Unlike most other systems, we do not try to reimplement something else, but rather tries to do things in our own (hopefully better) way.

The Trion Object Oriented Operating system is an OS that is designed to meet the needs for the 21st century, with a kernel written in C++ and modelled in UML, and lots of features. The project is run by a team of OSDev.org community members.

VSPMS is the "Very Simple Project Management System", which is a cross-platform set of shell tools and aliases to establish and share project environment variables, aliases, documentation, and setup procedures.

Wings is an OS for the 65816, in particular the C64 SCPU.

Yamit - Scalable, Portable and High Performance POSIX complaint OS. Microkernel based Operating System designed for tightly or loosely coupled multiprocessor hardware.
