Immer noch ein paar Fixes, aber das gehoert alles noch zu
v5.8 FINAL. In dem Punkt sind wir flexibel. Vielleicht wird's
auch erst eine BETA:

  • Kleine Korrekturen in den letzten uebersetzten /en-Dateien
  • Properties in computer/ gefixt

31    <p>In contrast to computers used for scientific applications, commercial data processing systems have a different structure since they are optimized to support large storage systems and to process lots of data like in payroll applications and the like. Sometimes the distinction between scientific and commercial systems is not a clear one. The examples below are typical small to medium systems for commercial applications.</p>

36          <b>Olivetti P 203</b>
37          <p>In 1968 the Olivetti P 101 with enlarged memory capacity was coupled with an electric type writer which led to a system capable of printing the results of computations directly. This system is of a remarkable design and won quite some prices for Olivetti in its time. The following machines made by Olivetti departed from that and were packaged in simple cubic enclosures.</p>

45            <p>Apart from desktop calculators other small computer systems were introduced to solve commercial problems. The <b>NCR 446</b> on display is a so called accounting machine and consists of a paper tape reader and punch, a keyboard and an IBM selectric typewriter as printer. It was built 1968 in Germany. Due to its core memory and woven ROM the machine is freely programmable and thus very versatile.

62              A typical small to medium data processing system is the <b>NIXDORF 820</b> built in 1969/1970. This system is built entirely from modules, has a magnetic account reader and a <a href="storage-media.shtm#threading-rom">threading ROM</a> which was user modifyable. The console consists of a typewriter, the magnetic account reader and two punch card readers. In addition to this the system supports a card punching unit, a high speed matrix printer (visible on the right), two cassette tape drives and a stand alone card puncher (IBM or YUKI, see above).
