Instructions for converting an existing Project Oberon 2013 system to Extended Oberon

If you run Oberon in an emulator on the desktop (e.g., http://github.com/pdewacht/oberon-risc-emu), you can simply backup your existing S3RISCinstall directory, download the compressed archive S3RISCinstall.tar.gz from this repository (containing Extended Oberon) to your emulator directory, run the command tar xvzf S3RISCinstall.tar.gz in that directory and then restart the emulator.
