I see this thread is still active, so let me add my 2 cents – and a calculator that most of the users of this forum probably have never heard of. ;-) In 1977 my school decided to order a substantical quantity of calculators so that students could buy these for very a good price. As far as I remember it came down to the choice between a TI-30 and another calculator sold by Quelle, a large German mail order store, under their "Privileg" brand. Finally the latter was chosen, so I got one of these. Recently I found it on the net, and so I think it must have been a model 585 D-E-NC as shown on thimet.de. Please note the dedicated ARC key for the inverse trig functions – just like the HP35. ;-) This calculator had two special, err... "features". The first one was its characteristic key click. Which actually was much more than a "click" – I remember that during math tests the room was filled with this loud clicking sound. The other feature may shed some light on the processor used in this device: Although the calculator usually worked with 8 significant digits, most transcendental functions (log, exp, trig) returned only 5-digit results. So lg 2 was simply 0,30103 – how needed more digits anyway ?-) But there also was an advantage over the TI-30 (which might have been a major reason for choosing this model): the Privileg had a rechargeable battery pack (3x AA) which was more convenient (and also much cheaper) than the 9V Alkaline battery used by the TI-30. The charger actually was a simple AC-adapter with a standard 3,5 mm jack plug. Three years later I acquired my first HP, a 34C. It was like entering a completely different world. Not just because of RPN. Dieter |
