     67              In 1970-72, <b>DIEHL</b> selled the <b>Combitronic</b>, featured with germanium transistors from the early 1960s
     68              (used for the printer interface), (still) a paper tape used for booting, a slow delay line memory and ceramic
     69              ICs (modern LSI technology). This device is a prime example for the enormous speed of development of new
     70              technology. The transistor logic was implemented by simply taking four LSI ICs together. Therefore the
     71              computer is logically identical to the almost obsolte Combitron, but the case is much smaller and the whole
     72              computer shrank up to two small boards (see <a href="/en/devices/diehl-combitronic.shtm">detailed pictures from the
     73              Diehl Combitronic</a>). In the picture above you see the compatible paper tape puncher ELS 850 and the reader
     74              "Dilector" on the left.

     78    <p>While DIEHL still emphazised the mechanics, HP tried to hide it as much as possible. For scientifical calculations
     79       the Diehl computers from the series shown above were too slowly, compared to HP or WANG, whereas the Diehl devices
     80       were much cheaper than the others. On the other hand, for normal calculations in engineering offices the
     81       perfomance of the Diehl devices was quite sufficient.
     82    <br/>For large scientifical calculations you had to buy Wang or HP devices.</p>

    6588            <ul>
    66               <li>In the center there is the HP 9100 (first electronical desk calculator from HP)</li>
    67               <li>Above the successor model HP 9810 (same logic but uses TTL-ICs)</li>
    68               <li>At the bottom the next model, HP 9820 (year of manufacture 1971)</li>

     89              <li>In the center there is the HP 9100 (see
     90                  <a href="/en/computer/programmable.shtm">Programmable
     91                  second-generation calculators</a> for description)</li>
     92              <li>Above the successor model HP 9810 (same logic like the HP 9100
     93                  but uses TTL-ICs), uses the very first LED displays that are
     94                  still very small and have only three rows.</li>
     95              <li>At the bottom the next model, HP 9820 (year of manufacture 1971)
     96                  with alphanumerical 7x5 pixel LED display.

     98              <li>At the top the best known computer from HP: HP 9830, year of manufacture 1972
     99                  with paper tape reader, puncher and plotter. This is the world's first desk
     100                  calculator that can be programmed with BASIC.</li>
