Project Oberon is a design for a complete desktop computer system from scratch.  Its simplicity and clarity enables a single person to know and implement the whole system, while still providing enough power to make it useful and usable in a production environment. This website contains information and resources for exploring and using the system.  The project is fully described in Project Oberon: The Design of an Operating System, a Compiler, and a Computer — written by the designers, Niklaus Wirth and Jürg Gutknecht. The second (2013) edition of the book and source code are published on Prof. Wirth's website. We provide links to the original material here, and local zipped copies, with kind permission from the authors.
