Be sure to read "Project Oberon, The Design of an Operating System and Compiler" generously published online as a pdf: http://www.ethoberon.ethz.ch/WirthPubl/ProjectOberon.pdf

There are emulators for Wirth's new cpu in JS, Java, C, and Python.

You can run it in the browser from here: http://schierlm.github.io/OberonEmulator/

(Shameless plug: https://github.com/PhoenixBureau/PythonOberon I wrote the Python emulator. It is sloooooooow, but it will boot and draw the screen (after a few minutes...)

Correct me if I am wrong, but the page has links to the book you mention as well.

However, the your link says Edition 2005 while the pdfs linked to by the posted page say Revised Edition 2013.

D'oh! My bad. I was just so excited to see Oberon on the front page.
