After some years I've restructured this page. A new system (Dokuwiki) is installed and the content ist cleared.
At this homepage you can find only one page in english, the tutorial ”Howto connect an Casio FX-880P (FX-850P) to an PC” (in a simply and cheap way).
The other pages about electronic and VDR are only available in german. For that pages click at “de” on the upper right of this page.
