- OS: Project is an Operating System Kernel ×
CleanOS is an operating system developed for educational purposes, initially to be an userspace GNU/Linux application running its executables and simulating the operating system task scheduler and IPC mechanisms. Now it supports a true i386 kernel.
Caracal Boot Loader (cboot) is a second stage boot loader which takes over from GRUB (or other multiboot compatible loader) and prepares the system for your higher-half kernel. It now also includes VESA mode setting support.1 weekly downloads

A small multitasking OS to run on 65C816 based systems. Features to include a GUI support for as much HW for the supported systems as possible and a system of system extensions for easy expandability of the OS. The initial Development is being done on the Apple IIgs, with plans to port to the Commodore 64 with a SuperCPU. Eventually there will be ports to other 8 and 16-bit CPUs beginning with the 6502, followed by the z80, 6800, 6809, 8086, PDP-11, and then the TMS9900. Once these are complete there will be 32-bit ports to the 680x0, ARM, MIPS, etc.
