In addition to Oberon V4 for Linux this project is now host to the collection of Oberon V4 sources for different platforms which in the past was hosted on http://claudio.ch. You can find them in the "V4 Sources" repository.
I've finally managed to put 1.6.02 on sourceforge.
Also note the new homepage.
There's a new release! Check out http://sport1.uibk.ac.at/tanis/oberon.linux.html
