This device is very fast and versatile and works mostly 80 electronically. Most likely, Univac wanted to trump IBM with this 81 trendsetting device. The device's internals are very elaborate, but offer 82 many advantages, compared to usual apperatures at that time: 83 <br/>It featured semiconductor storage for both data and programs. It could 84 handle eight programs and four auxillary data storages – programming 85 was performed automatically once program cards have been inserted, and 86 programs could be changed at the touch of a key. The device furthermore 87 featured program-controlled printing during punching and verification; 88 Keypunching errors were electronically corrected, since cards were punched 89 only after all entries were in storage. Verifying and correction comprised 90 a one-pass operation. Verified cards were uniquely notched while error 91 cards were automatically ejected to a separate stacker. 92 <br/>The device also features a large illuminated digital display that 93 indicates which program is in control, furthermore the device could be 94 used for subsequent card labeling. However, the device had always 95 mechanical problems: The type wheel print was of bad quality and the 96 card feeding could easily stop working when the adjustment wasn't 97 perfectly fitting. 98 </p> 99 </div> 100 101 <div class="box center"> 75 102 <a href="/en/devices/punchcard-sorter.shtm" name="backlink-sorter"><img src="/shared/photos/rechnertechnik/ibm-082-sorter.jpg" alt="IBM 082 sorter" width="361" height="287" /><img style="margin-left: 2px;" src="/shared/photos/rechnertechnik/ibm-082-sorter.offen.jpg" alt="IBM 082 sorter (without cover)" width="215" height="287" /></a> 76 103 <p class="center"> -
