TORO is demonstrating an innovative operating system by integrating at the same ring level both kernel and the user application server. The threads of the user application server are distributed evenly on all CPUs and running independently in parallel. The memory model chosen is NUMA without pagination. During the initialization, the memory is divided proportionally for each processor installed on the system. When a thread needs memory, the memory allocator returns a free block of memory depending on which CPU the thread is running. In the same way, TORO can dedicate resources to specific processor, i.e. a FileSystem. This only CPU then can access to this instance of FileSystem. The scheduler is based on the cooperative threading model, therefore due to this design, TORO can migrate threads between CPUs and send messages between threads without using any lock instruction. TORO is well suited for integrated system to run at high pace application servers like web servers.
DelphineOS is a "unix-like" OS designed for i386 processors and higher. It uses 32bits, protected mode, multitasking, virtual memory... The source code is written in PASCAL. If you want to HELP us, send e-mail to firstname.lastname@example.org
Oberon V4 for Linux and sources for different Oberon V4 implementation
Here you can find both an Oberon V4 system for Linux (x86) as well as a collection of sources for various other platforms. Oberon V4 was implemented at ETH Zurich for several platforms. Binaries can be found on their server and on the one of the University of Linz where Mössenböck's group did further development after he left ETH and the Group at ETH concentrated on System 3. More Information can be found in the wiki https://sourceforge.net/p/oberon/wiki/Home/ of this Project and on Wikipedia https://en.wikipedia.org/wiki/Oberon_(operating_system). In 2013 they were moved here for easy access and, in case of interest, collaboration on further development. The Oberon mailing list is an established channel for its discussion and followed also by the administrators of this SF project.  ftp://ftp.ethoberon.ethz.ch/Oberon/OberonV4/  ftp://oberon.ssw.uni-linz.ac.at/pub/Oberon/  https://lists.inf.ethz.ch/mailman/listinfo/oberon
Perix is a 16/32 protected mode kernel, bootable and capable of running without an operating system. It is written in Turbo Pascal 7.0 for DOS, Delphi 7.0, Pascal Pro, Virtual Pascal v2.1, TASM and JWASM. Turbo pascal version can be used as kernel on its own, or as a second stage loader to external programs. I would like to announce, that the first attempt to put the Delphi 64bit to work was successful. As soon as possible I will place at the disposal a very small 64bit kernel version.
Topologilinux is a complete slackwarebased linuxdistribution to be run on top of any Dos/win partition without partitioning your hard disk. Very easy to install to your favorite Windows system like Windows Vista or Windows XP or Windows 2000.
SD is a new operating system developed in the Pascal language (FreePascal, FPC/FPK) and NASM for IA-32. It's main purpose is to provide a fast and simple 32-bit multitasking OS. The OS must have several DOS, Windows and Linux features and maybe Win32 emu.
Achelous is attempt to clone Mac OS X for the Intel X86 Chipset. There are currently two teams working on the project: the Kernel team and the GUI team.
A new advanced customizable graphic menu multi boot and OS loader based on XOSL project with gujin project features, this project integrate too a mini OS to provide certain customizable specialized maintenance tasks before boot partition/load OS target.
A multiplatform programming language for every kind of platform from a microcontroller to a computer,Based on Adaptors and Terminals,It means you designing Adaptors and Terminals and Concat them(e.g for type a key on keyboard and displaying in monitor you
This is a project to develop a operatingsystem totally writen in Perl. It will maybe be like Linux and finaly when it has been developed for a while then it should have its own startup file like msdos.com or what it is called in dos and this file would be
NuzulOS - pascal operating system
NuzulOS is my operating system whis is develop in pascal environtment.
Pascal Operating System, That will translate Freedos to Pascal --OSPine written in Turbo Pascal and NASM. I think now I will make all that useful before I release. Thank for Feedback (^_^)
Perix is a MS-DOS compatible program, capable of running without an underlining OS. It is written in Turbo Pascal and Assembly. All parts of system are distributed under terms of the GNU General Public License v2.
Plato is an open-source operating system designed to run binaries from almost any operating system. Plato is also desinged with the user in mind. It will have an enjoyable, easy to understand and use interface, and everything will be customizable.
What can compete with hierarchical file structures and class/inheritance schemes if not networking organic type/form languages, with its own graphical and DOS compatible OS? This initiative always moves fast ahead, and in an enlightened way... GNU GPL
a new kind of OS. just an experimental and limited system to test a new concept based of user centric view, but nothing is done because it's "normal" in all OSes , everything is thinked again. The aim is to manage information (represented as XML) wit
nucleOS will be an 32-bit Operating System (perhaps we'll make it 64-bit later), written in Pascal and Assembler. It will be based on the i386 architecture and will support multi-tasking later on. Project is dead since 2006-03-19.
open source analogue of IBM OS/2 operating system
