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. 75 </div> 76 </div> 77 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> 83 61 84 <div class="box left"> 62 85 <img src="/shared/photos/rechnertechnik/hp-rechner.jpg" alt="HP desk calculators (panorama)" width="335" height="1045" class="nomargin-bottom" /> … … 64 87 <p class="left">The history of development from the HP-desk calculators in one rack:</p> 65 88 <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> 69 <li>At the top the most known HP-computer: HP 9830, year of manufacture 1972 with paper tape reader, puncher and plotter</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. 97 </li> 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.
