Oberon V4

Here you can find both an Oberon V4 system for Linux (x86) and a collection of Oberon V4 sources for various other platforms. Oberon V4 was implemented at ETH Zurich for several platforms. Binaries can be found on their server[1] and on the one of the University of Linz[2] 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[3] is an established channel for its discussion and followed also by the administrators of this SF project.
