The Oberon System is an academic operating system and an integrated software environment developed by Niklaus Wirth and Jürg Gutknecht since 1980s at ETH in Zürich. Initial release: v1.0, Latest Release: December 2018 The website is written like a textbook to explain how it all works, focusing on the implementation rather than theory. There are very simple example user programs to demonstrate threads, message-passing and interrupts. When the system starts it loads a server that allows the user to load their own processes. As with most microkernels, the drivers run in user space and help to demonstrate message passing and interrupts. It also has a basic text-mode display driver and keyboard driver. It has its own basic boot loader that loads the kernel and a disk driver. It is currently targeted for the IA-32 processors, but the design is strictly separated into a hardware-dependent mechanisms layer, with an independent policy layer on top of that. It has pre-emptive multitasking with threads, message-passing and virtual memory. The BlueKernel is a simple microkernel design intended for students. Last commit:, currently abandoned - the author has switched to his other project, Rust OS ( ) Open source inside the source code archive there are broken symlinks /Kernel/arch/x86_64/rme.c and /Kernel/arch/x86_64/rme.h to Real Mode Emulator files which are available here. Could try building a new floppy from the latest sources by yourself! (some software rot has been noticed but its fixable) v0.14 outdated floppy image is available at its' old page: username - root, password is blank. Recently, this project has been moved to GitHub, but its old git repo-with outdated sources and some useful documentation-can be found here: a=summary. It features a simple but extensible VFS that currently supports VFAT and Ext2, IPv4/IPv6 networking with TCP/UDP, USB input, and storage. However, unlike Linux, it there is no need to maintain backwards compatibility with anything. Particularly advanced and successful operating systems are listed at Advanced Projects.Ĭontents: 9 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 9Īcess2 is a kernel and operating system designed to do what Linux does, be customizable to any given situation. More mature hobby operating systems can also be found at Notable Projects. OSes without an update since 2015 are now located at Abandoned Projects. Please help keep this list current by correcting it if you see any outdated information. And looking at how often these projects are started by using the OS Project Announcement forum, in that same time period 68 projects were announced! The current total is 175 projects, but just 58 of them are active (as of January 1, 2018) and only 62 have been updated at least once since 2018 (three of which have been since abandoned), and 27 since 2019. OSes have a high mortality rate: between 20, 112 of 213 OS Projects disappeared from the Internet. For information regarding commercial or mainstream operating systems, please visit Wikipedia. This page maintains a list of academic, personal, and small non-commercial operating systems.
