About 45 user contributions for language improvement of the English homepage. Thank you so much! Unfortunately the system wasn't fully finished at that time (last weekend) so I don't have your names/locations yet :( - so if you read this text and want to be mentioned on the website, just write a mail.

    2727    modern-looking monster features 188 electron tubes and belongs consequently to the first
    2828    generation of calculators. It has a wonderful glowing display. However, the
    29     tube based computer can only compute with the four basic arithmetic operations and
    30     costed the price of a VW beetle and an holiday trip.</p>

    43            obsolete in 1962. The calculator works in decimal system, just as every other

    7070        The upper circuit board contains a ring counter. The gas-filled thyratrons are very small. This
