     268<p>Recently we saved this large (70cm by 60cm) and wonderful "decoder" from scrap
     269at a local university. This device translates 5 bit telegraph codes to their
     270corresponding characters. It has been built as a demonstration object by the
     271university's machine shop sometime between 1937 and 1949 and has been used
     272extensively in lectures.<br>
     273Principle of operation: A 5 bit value is set by means of the large levers. Then
     274the code wheel is turned slowly until the correct character is in the top
     275position which is denoted by lighting a lamp. If, e.g., 10101 is set and the
     276code wheel is turned, the lamp will be lit under the character "Y".<br>
     277What once was state-of-the-art technology is now used as a decoding device for
     278our experimental workshops. There kids can decipher texts given in binary and
     279thus gain experience with binary data representation.</p>
