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
