(in this case we don't need to press enter key)īut in an algebraic calculator we have two ways. What about calculate sin(33)? In a RPN calculator it is just do 33 sin In a bad algebraic calculator which does not know this we have to do In a RPN calculator we do 2 ENTER 79 x 4 +īut how one could do this in an algebraic calculator? If the calculator has the ( and ) sings it is just doīut if there are no () we do this in a good calculator by doing 4 + 2 x 79 =īy a good calculator we mean a calculator which knows that x and / are prior to + and. Lets now consider the following calculation 4+(2x79). To make this using a RPN calculator we do 2 ENTER 2 +Īs we can see in RPN mode we first enter the data pressing the ENTER key after every data (except for the last in HP's RPN) and then we enter the operations. In RPN we first enter data and then we enter the mathematical operations.Įxample: To make a simple operation like 2+2 in a normal algebraic calculator we do 2 + 2 = RPN comes from “Reverse Polish Notation”. HP-42S as most old HP calculators was a RPN calculator.

And also would be nice to have HP-42S roms for free just like what happened to HP-48G and other models and keeping PDF versions of the manuals of retired models to download would be nice too. I would like to finish this introduction saying that would be nice to have HP-42S back to life again and even better to have a model (both real and in simulator/emulator form) based on HP-42S but with some of the 33S features like more memory and equation editor, fractions, program lines starting with letters, physical constants, units conversion, less useless functions, etc. Try asin(acos(atan(tan(cos(sin(6°)))))).įor more information about HP-42S please see

In my opinion Free42 is even better than the real HP-42S. If you want to download the fantastic Thomas Okken Free42 program please go to this web site This because I suppose most owners don't have the printer (and it is not so useful) and also haven't had a HP-41 prior to HP-42S. Two things I really don't want to see here are PRINTING and HP-41 compatibility.

#HP RPN SCIENTIFIC CALCULATOR 42S MANUAL#

It is important to say that this manual is not complete and I don't want it to be. This calculator played an unique position among HP calculators! Being a scientific programmable 100% RPN calculator, it also had some graphing abilities but was pocketed sized and non RPL (some people as me like RPN, but dislike RPL).

And because there is a free simulator (Free42) that works on Palm OS, Windows and Linux and there are also some emulators (at the moment emulators are only useful for who has a real calculator since HP-42S roms are not freely available). I know some other HP models from the past and the present like 48G, 49G, 28S, 33S, 20S, 6S Solar, 15C, and even a TI-36X Solar, etc, but 42S is my favorite. Why HP-42S? Because it was a very, very nice calculator and also a powerful one.

#HP RPN SCIENTIFIC CALCULATOR 42S HOW TO#

I have a HP-33S and had a HP-48G, but my brother has one and I also use Free42 simulator for PalmOS.Ī) Have a HP-42S calculator and lost its manual.ī) Got the Free42 simulator and want to know how to use.Ĭ) Have a palmtop with PalmOS and want a nice scientific calculator (get Free42)ĭ) Just want to have an idea how 42S was.Į) Have the official manual but don't want to read more than 300 pages! I personally don't have a HP-42S (more than U$300 on ebay). Since HP-42S was a very nice calculator, and its official manual is no longer freely available and there were many people looking for its manual, seemed good to me to write my own HP-42S manual.
