To make this using a RPN calculator we do2 ENTER 2 +Īs we can see in RPN mode we first enter the data pressing the ENTER key after every data (exceptfor 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 do2 + 2 =which give to us 4.
HP-42S as most old HP calculators was a RPN calculator.

And also wouldbe nice to have HP-42S roms for free just like what happened to HP-48G and other models andkeeping 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 againand even better to have a model (both real and in simulator/emulator form) based on HP-42S butwith some of the 33S features like more memory and equation editor, fractions, program linesstarting with letters, physical constants, units conversion, less useless functions, etc. Here you can find emulators for HP-42S (very nice) Try asin(acos(atan(tan(cos(sin(6°)))))).įor more information about HP-42S please see If you want to download the fantastic Thomas Okken Free42 program please go to this web site my opinion Free42 is even better than the real HP-42S. This because I suppose most ownersdon'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 reallydon't want to see here are PRINTING and HP-41 compatibility.
Free42 simulator 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 programmable100% 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) thatworks on Palm OS, Windows and Linux and there are also some emulators (at the momentemulators are only useful for who has a real calculator since HP-42S roms are not freely available). I know someother HP models from the past and the present like 48G, 49G, 28S, 33S, 20S, 6S Solar, 15C, andeven 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. e) Have the official manual but don't want to read more than 300 pages! c) Have a palmtop with PalmOS and want a nice scientific calculator (get Free42) d) Just want to have an idea how 42S was.

b) Got the Free42 simulator and want to know how to use. I have a HP-33S and had aHP-48G, but my brother has one and I also use Free42 simulator for PalmOS.Ī) Have a HP-42S calculator and lost its manual. I personally don't have a HP-42S (more than U$300 on ebay). It is written in C and uses the X window system for display.Since HP-42S was a very nice calculator, and its official manual is no longer freely available andthere were many people looking for its manual, seemed good to me to write my own HP-42Smanual. Nsim is a microcode-level simulator for the HP-41CV programmable scientific calculator.
In particular, numerical results will be identical, because the simulator is using the BCD arithmetic algorithms from the calculator. Simulation fidelity is achieved through the use of the actual microcode of the calculators, thus in most cases the simulation behavior exactly matches that of the real calculator. It currently supports many HP calculators models introduced between 19. Nonpareil is a high-fidelity simulator for calculators. This emulates exactly what it says it does. You do not need any ROM images in order to use it, yet it is fully HP-42S compatible. Free42 was written from scratch, without using any HP code. Free42, a cross platform emulator, is a complete re-implementation of the HP-42S calculator and the HP-82240 printer.
