MTX User's Club - Germany

The German user group seems to have been very technically orientated, with quite a number of hardware projects being developed for the MTX and FDX. The MTX User's Club (Germany) was the most long lived of the MTX User groups and was active until at least mid 1992.

The MTX User Club Germany was run by Herbert zur Nedden, who also produced the MTX-Info magazine.

Peter Kretschmar has scanned copies of the MTX-Info magazines which Herbert is offering for sale at 15 Euros on his web site. The CD contains 46 issues of the magazine, along with some PD software.

Unfortunately, being unable to speak or read German, although I may be able to find something useful on the CD, I can't really justify the cost of taking a chance. If you have some grasp of German, you may like to obtain a copy of the CD from Herbert.

Someone (who shall remain nameless, you know who you are - thank you!) has sent me copies of the magazines, but for the reason given above, I am unable to make them available for download.

This page shows some boring images of the cover page from the magazines, but the magazine contents are not available for download from this page. I will try and work through the magazines, doing my best to highlight the most useful content in each issue, but, with having no German language skills, this will likely take some time, particularly as they do not convert to text very well with my OCR software, making it difficult to even run them through Google Translate.

NB : I have not done justice to the contents of the magazines, they really do contain a lot more useful tricks & tips as well as interesting technical notes.

From Issue 11, the magazine contains an index which may give you a clue as to whether there is anything of interest to you in that edition.
