Welcome! These pages collect everything I thought to be useful for you. Most of these things are rather old, but if you're addicted to computers as I am you know what I mean. Much of the documentation is in german; if you like to translate it and send it back to me, you're welcome! Links for downloads and detailed descriptions are in the tables below.
