r70 r73 69 69 ICs (modern LSI technology). This device is a prime example for the enormous speed of development of new 70 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 whole71 computer is logically (almost) identical to the almost obsolte Combitron, but the case is much smaller and the whole 72 72 computer shrank up to two small boards (see <a href="/en/devices/diehl-combitronic.shtm">detailed pictures from the 73 73 Diehl Combitronic</a>). In the picture above you see the compatible paper tape puncher ELS 850 and the reader … … 80 80 were much cheaper than the others. On the other hand, for normal calculations in engineering offices the 81 81 perfomance of the Diehl devices was quite sufficient. 82 <br/>For large scientifical calculations you had to buy Wang or HP devices.</p> 82 <br/>For large scientifical calculations or even more complex jobs you 83 had to buy Wang or HP devices.</p> 83 84 84 85 <div class="box left">
