From that link: "Leider fehlt der gewohnte Tastenwiederstand bei diesem Gerät" (tactile feedback is missing)

Interesting, "Wiederstand" should actually be "Widerstand" :-)


Hallo Thomas,

Dynatech is a big calculator source for teachers. So, what does it tell us if such a site is not capable spelling German properly? Or does not spend time for proofreading? No further comment :(


That's not the only typo. Punctuation is a bit strange, too.

I've just sent an email to info@dynatech.de:

HP-20 b - Rechtschreib- und Grammatikfehler auf Ihrer Webseite.

Sehr geehrte Damen und Herren,

durch einen Hinweis im Forum http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/forum.cgi bin ich auf HPs neuesten Taschenrechner HP-20 b aufmerksam geworden. Leider strotzt der Text auf Ihrer Webseite nur so von Fehlern. Ich habe mir erlaubt, Ihnen hier eine korrigierte Version zu schicken:


Der neueste Spross aus dem Hause Hewlett Packard wird schnell seine Freunde finden!

HP punktet mit diesem Modell durch seine einfache Bedienung, das schlichte aber dennoch raffinierte Design, die Menüzeile (obere Zeile) und durch die vielen zusätzlichen Funktionen.

Wer den HP-10 B II bereits kennt, wird sich über die Neuerungen freuen. Ganz besonders muss man hier die Menüsteuerung erwähnen. Am Anfang wirkt diese etwas spartanisch, aber auf den zweiten Blick... Simplifikation ist das Stichwort.

Leider fehlt der gewohnte Tastenwiderstand bei diesem Gerät. Dennoch ist die Tastatur im Vergleich mit anderen Herstellern obere Mittelklasse.

Neben den finanzmathematischen Erweiterungen ist der Rechner speziell im Hinblick auf die Bedürfnisse im Studium überarbeitet worden. Mathematische Funktion wie Trigonometrie, hyperbolische Funktionen, Permutationen und Kombinationen und noch vieles mehr wurden hinzugefügt.

Diesen Rechner können wir für jedes Studium in Richtung Finanzen, Unternehmensführung, Marketing, öffentliche Verwaltung und Volkswirtschaft empfehlen!


Auf Ihren Seiten verkehren viele Lehrer. Sie machen mit dem Originaltext keine gute Werbung für sich bei dieser Klientel.

Mit freundlichen Grüßen

Marcus von Cube

Naja! Glashäuser & Steine ...

I'm thrilled HP is introducing new calculators, and if some are non-programmable that's fine too as they are good for exams that don't allow programmable calcs --- but when will these newer models be available on this side of the Atlantic?

The HP 17BII+ (silver) with full-width Input key was released in Europe in Fall 2007, yet as we approach Summer 2008 is still not available at, for example, SamsonCables or CalcPro. Does that mean another year of waiting for availability here of the HP 20B as well?

17BII+ Silver. Buy.com. $83.99.


17BII+ Silver. Buy.com. $83.99.

Yeah, I also have noticed the slow proliferation of the newer image of the HP 17BII+ (Silver) on some US online sites. But I wonder if anyone has ordered the above and actually received the HP 17BII+ (Silver) model? Or did they receive instead the older brown and gold model without the double-width Input key? Both are identically marketed by HP as the "HP 17BII+". Does "model shipped may not exactly match illustration" apply?

As was mentioned, specialty shops such as SamsonCables and CalcPro, whose business is about having the newest and latest models, amazingly are still showing only the older brown and gold HP 17BII+, as is the case too for Amazon.com.

I've been told by one vendor that the reason for the slow introduction of the HP 17BII+ (Silver) model on this side of the Atlantic is due to unsold inventory of the older version of the HP 17BII+ model. And it does make one wonder -- why else would HP introduce a new case-design, yet retain the old model designation, unless maybe they wanted to facilitate retailers clearing out old inventory?

I ordered an HP 17bII+ from HP directly (U.S.) and I received the new silver model. If you look at shopping.hp.com they show the new silver version. I assume that now that is the default one that is shipped, but you may call to be sure.


Interesting. Scientific, trig, combinations, permutations, etc., and business. I'm intrigued.



Anyone remember the HP-27 (LED Woodstock all-in-one from the mid/late 70s) ?

Looks like same idea updated.

HP-27 is quite a rare bird today.



Additionally, you may recall the HP 27S, just 20 years ago. It was one of HP's cleanest designs :) though not RPN. I prefer its way of placing soft keys in the *lower* display line. The 20b has a rudimentary space for menu items top left only, instead, far away from the respective keys :(

No programming and not RPN. :(


Looks like 20B lacks programming, but has RPN available.

[Umgekehrte polnische Notation + ] (from German web site)

My 0.02...




I've just read the line. ;) On the blurry picture, a "mode" key can be identified. I was just guessing from the "=" key that it were an algebraic only device.


No scientific notation?

Wissenschaftliche Notation (Eingabe) -

Then I wonder what this EEX-key is for.

Hmm, a new LCD within a pioneer case. Does this mean we can expect a new scientific platform?

I'd be very surprised if HP just left it at the financial version.
I love dual 7seg/dot matrix displays.

I feel a HP 20SII coming on...

Seems like a replacement model for HP 10BII.


To me it looks more like a Texas Instruments BAII Plus remake than a successor of the HP 10B II.



Hi Joerg,

the keyboard layout with the BIG Enter, aehh INPUT key is similar to that of the HP-17BII,

with the obvious differences, of course;-)
