The cards are read in the reader 27 station which transmits data to the computer.<br> The computer in turn performs all 28 necessary calculations and transmits the results back to the punched card 29 machine which will print or punch these values.

r481 r482 112 112 <b>IBM 514</b></p> 113 113 114 <p>......will be translated soon</p> 115 <p>Seit Dezember 2013 im technikum29: Gigantisch groß und gigantisch schwer, der Lochkartendoppler von IBM aus den 50er Jahren. Dieses stattliche Gerät war nur dazu da um Lochkarten zu duplizieren. Natürlich sind auch noch ein paar zusätzliche Funktionen vorhanden.<br> 116 Durch die starke mechanische Beanspruchung der Lochkarten während des täglichen Betriebes mussten diese nach einer gewissen Zeit erneuert werden. Der Doppler kann jedoch die Karten nicht gleichzeitig beschriften. Dazu war dann ein Lochschriftübersetzer wie z.B. der IBM 548 notwendig (siehe weiter unten).</p> 114 <p>New in December 2013: Huge and incredibly heavy - an IBM card doubler from the 115 1950s. This grand machine's purpose was just to copy punched cards or to 116 'double' them. Due to the stress of handling, punched cards had to be copied 117 regularly. 118 <br>Of course, there are some additional functions implemented, although 119 there is no function to print plaintext on the card, which would have been a 120 nice feature, but this is where the IBM 548 translator comes into play. 121 A more detailed description will follow soon.</p> 117 122 </div> 118 123
