    7878           trendsetting device. The device's internals are very elaborate, but offer
    7979           many advantages, compared to usual apperatures at that time:
    80            <br/>It featured semiconductor storage for both data and programs. It could
    81            handle eight programs and four auxillary data storages &ndash; programming
     80           <br/>It featured CORE memory of 12x80x2 cells for both data and programs. It could
     81           handle two programs and one data storage. Programming
    8282           was performed automatically once program cards have been inserted, and
    8383           programs could be changed at the touch of a key. The device furthermore
    84            featured program-controlled printing during punching and verification;
     84           featured program-controlled printing during punching.
    8585           Keypunching errors were electronically corrected, since cards were punched
    8686           only after all entries were in storage. Verifying and correction comprised
    8787           a one-pass operation. Verified cards were uniquely notched while error
    8888           cards were automatically ejected to a separate stacker.
    89            <br/>The device also features a large illuminated digital display that
    90            indicates which program is in control, furthermore the device could be
    91            used for subsequent card labeling. However, the device had always
    92            mechanical problems: The type wheel print was of bad quality and the
    93            card feeding could easily stop working when the adjustment wasn't
    94            perfectly fitting.
