Overview Download Decision-Computer-Merz e.K. and Decision-Group-Taiwan. Please search German area first. Taiwan is temporarily out of date. German manuals are bugfixed and therefore always preferable to the Taiwan version!
Should you not find a manual or driver please contact me by email!

The German and English manual offers improved, bug-fixed and more comprehensive information. It is continuously updated and is therefore preferable to the Taiwan Manual. Suggestions for improvements are welcome! At Manual - English some are still in work. The English manual from Taiwan is the original version. Some instructions from very old and little sold boards I didn't include in this download area. But every manual is available. Please inquire if necessary. A board photo is mostly helpful for identification!
