In this 69 case a curious student at the Goethe University discovered strange objects in a 70 building and informed us. It turned out that these devices were a <a href="/en/computer/punchcard.shtm#u1710">UNIVAC 1710</a> 71 72 card puncher and a cabinet full of punched cards containings programs for our 73 UNIVAC 9200. The punch cards, about 65000 pieces, contain programs which were 74 developed between 1967 and 1975 at the institute of mathematics and applied 75 computer science. We will surely revive some of these old programs on our 76 UNIVAC system. <br> 77 The rescue action was actively supported by the University of Frankfurt and 78 the "FITG" (Frankfurt) whon we would like to thank for their efforts.</p> 79 <div class="box center auto-bildbreite"> 80 <img src="/shared/photos/rechnertechnik/univac/lochkarten.jpg" alt="65.000 punch cards" width="700" height="174" /> 81 <p class="bildtext">24 boxes containing more than 65000 punch cards extend our software library</div> 82 83 <p>NB: One punch card can hold up to 80 characters - that makes about 80 bytes 84 per card. Thus 65000 cards correspond to about 5 MB which is roughly the same 85 amount of data that a modern digital camera produces for a single picture. 86 Stored on punch cards 5 MB weigh about 160 kg while the cabinet housing the 87 cards has a volume of about 0.5 m³ (about 500 liters of volume).</p> 88 65 89 66 90
