     59                <p>Also interesting are typical paper tape accessories as shown below. It is
     60next to incredible that not too far ago programs had to be prepared with
     61tools like these. The figure below shows a manual paper tape punch on the left
     62which can be used to punch programs on a paper tape. For the most basic version
     63of the NCR 446 which lacked the attached paper tape punch, this was the only
     64way to create program tapes!<br>

     70                <p>Programming in those days was done as follows: First, the program was written
     71down by hand. Each character was then translated manually using a NCR
     72supplied code table to its corresponding numerical code. The paper tape was then
     73punched by a secretary. Correcting errors was obviously rather cumbersome and
     74time consuming.<br>
     75
     76The NCR 446 in the museum's collection allowed the creation of paper tapes by
     77means of the built-in keyboard and the automatic paper tape punch
     78unit at an additional cost of 20,000 DM (10,000 EUR).<br>

     80The motor driven paper tape winder shown on the right could be used to wind
     81the paper tapes after using them on the computer. </p>
