Build Your Own Classic HP Calculator Emulator
- Aardwolf 5y agoNice, I'm a sucker for things like this! Why such low resolution photographs though (can't even properly see what the buttons are like), and why use a framework for the images that doesn't even allow to do "view image" to be able to zoom in to it?
- teddyh 5y ago> I wonder why there aren’t any RPN calculators anymore. In Unix, terminal: dc In Unix, X11: xcalc -rpn In Emacs: M-x calc On Android: https://search.f-droid.org/?q=rpn https://search.f-droid.org/?q=rpn
- trasz 5y agoAlso Free42; no idea about Android, but works perfectly on an iPhone. (Which, funnily enough, almost exactly matches HP42’s physical dimensions.)
- Baeocystin 5y agoDroid48 on the play store. https://play.google.com/store/apps/details?id=org.ab.x48&hl=en_US&gl=US https://play.google.com/store/apps/details?id=org.ab.x48&hl=... As my (still functioning!) HP-48 was my first True Calculator Love, I am happy that this app exists.
- copperx 5y agoI'm still bitter someone stole my 48G. But Droid48 does everything it did (and it's always in my pocket!).
- trasz 5y agoHP48 was my first HP calculator too, but over the years I realized I like 42 more. 48 was great back in the day, but nowadays I don’t need to use it for more complicated stuff - and for simpler things 42 is just more convenient.
- wtallis 5y agoOn my phone, I prefer Emu48, with a 50g skin. It ends up being almost exactly the same scale as the real calculator, so my muscle memory from the 50g transfers over about as well as possible give that it's on a touchscreen instead of a real keyboard. And the extra screen space over the 48 series sometimes comes in handy.
- hungryforcodes 5y agoI love your list -- but that you have to spell them out, indicates they're not really that adopted.
- Jtsummers 5y agoApple’s builtin calculator in macOS has an RPN mode. One click from a menu and it becomes the default after that, IIRC.
- fmajid 5y agoSwissMicros makes recreations of the classic HP calculators that are arguably superior to the originals, specially the DM15L and the DM-42: https://www.swissmicros.com/products https://www.swissmicros.com/products
- copperx 5y agoI now know what my birthday present to myself is going to be.
- joezydeco 5y agoThat's amusing that SwissMicros branched off the work of Free42, a free (as in beer) reproduction of the HP-42S calculator. https://github.com/swissmicros/free42 https://github.com/swissmicros/free42 The author created and continues to support a build of Free42 for iOS, completely free. It's one of the most useful apps on my phone. My real 42S stays safe on a shelf. https://apps.apple.com/us/app/free42/id337692629 https://apps.apple.com/us/app/free42/id337692629
- fmajid 5y agoYes, their innovation is in hardware, not software. I also keep my 1986 HP-15C safe and use a DM15L as my everyday calculator (a new meaning for EDC...). In fact I had a NIB HP-15C LE reissue (two, in fact, but one was stolen) and resold it when I got the DM15L (and a second one for redundancy), it's a much better calculator. I have Free42 for my iPhone and iPad but I tend to use the [official HP HP-15C emulator app](https://apps.apple.com/us/app/hp-15c-calculator/id503720774 https://apps.apple.com/us/app/hp-15c-calculator/id503720774) instead, or PCalc.
