The "Magazine Articles" section of the Elektor Coding Guide at
http://amigan.yatho.com/e-coding.txt gives a list of articles contained
in these archives. These archives contain mostly projects and their
errata.
  There is a lot of other interesting material (eg. advertisements) not in
these archives that may be of interest. See the list at
http://amigan.yatho.com/mags.xls (although it is not exhaustive).
