Of course, HP calculators used RPN, but if you grew up with a slide rule that’s fine. For everyone else, it is usually a bit of a learning curve. Also, as great as the HP41C was, it didn’t have binary or hex or even octal math unless you used “synthetic programming” and though we imagine the emulators used can handle synthetic programming (sort of assembly language for the HP41C) it was never fun to work on non-decimal problems with this machine. Still, what a great calculator and it is fun to see it reborn in modern form. We’ve seen another fake HP41C that we think is using the same emulation software but required SMD soldering. Posted in Retrocomputing Tagged calculator, hp41c, retrocomputing Post navigation We wonder if the KIM Uno or 1802UNO could be made to run on the same hardware? Seems like it would. Indeedee do dee, may the forth be with you.įwiw. My first experience with Forth, which prepared me well for RPN, was a nice piece of software on a nucleonic ore flow gauge measuring (mostly) realtime iron ore flow mass pre grading screens written initially by Dav Gibson Pretron Electronics. Used a Pace-16 by NS, paper tape 2708 aprons, with an 8 deep stack 16 bit fixed point computational shell all written in assembler ie the code all subroutine calls to the complicated equation to assess mass flow in tonnes per second from differential attenuation of beta particles (Cs137 upgraded to Co60) through a falling magnetite ore curtain with scintillation counters each end exactly one meter vertical separation – nice formula to get absorption to mass flow !Ĭalibration an issue with a work around for transience via a Kalman filter written by Indesa Rajasingham who visited Mt Newman mining circa 1978-9 to interface his filter and my code to a Foxboro controller. Site visits with Peter Moore under management by Ray Stubbs. Some great experiences, all started off by the tech school having a program to introduce students to industry – lucky I did well in programming, paid really well too…Ī couple of notes about Free42 and Windows:ġ. In Windows, Free42 is a stand-alone/portable application. Zip archive into a folder anywhere and double-click Free42Decimal.exe file to run it. You can ignore the Free42Binary.exe file, the difference between the two files is explained in the README.txt file contained in the. To uninstall Free42 delete the install folder. To upgrade Free42 delete the old files in the install folder and unzip the new downloaded. In Windows if Free42 won’t start, the solution is very likely explained in the README.txt file contained in the download. “If Free42 does not run as is, you will also need to download and install the Visual C++ Redistributable for Visual Studio 2015 / 2017 / 2019. ![]() (Get the file vc_, even if you are runnin a 64-bit system.)” Free42 android install# If you want a new physical HP RPN scientific calculator you can still buy the HP-35S for around sixty bucks. If you use Free42 you’re welcome to download it and give it a try.‘The HP 35s (F2215A) is a Hewlett-Packard non-graphing programmable scientific calculator. It’s a bit ugly because of my limited options for font choices (and limited skill), but I’m a lot happier with it than any of the themes provided on the developer’s site. So I created my own skin for Free42 based shamelessly on PCalc’s Samurai theme. I want the functionality of the calculator, but don’t much care for trying to emulate the look of the actual physical buttons. These aren’t bad, but I’ve really taken to the more modern, flat styling used in the PCalc Samurai theme. The standard skins provided on the project page generally make this very clear, as most are based on photographs or scans of the HP 42s calculator itself. I’ve taken to using the truly excellent PCalc for iOS for general calculation where I don’t have the HP calculator, but I also use an HP 42s calculator simulator called Free42 on Windows when I’m at the office.įree42 isn’t an emulator as it doesn’t use the actual HP roms, but it is an accurate simulator of the calculator. I have an HP 35s which is supposed to be at my desk at the office, but is currently at home. Over the last few years I’ve taken to using RPN for general calculations instead of the more common algebraic notation. Simple Modern Skin for Free42 HP 42s Calculator Simulator
