Gosh I need one so badly. Used ones are up to about 500USD. Pity the international shop is down

hp48 is still on Android for free, as HP released the ROMs to public domain while they were still an awesome company. The unit converter is still very handy. =3 https://play.google.com/store/apps/details?id=org.ab.x48&hl=en https://play.google.com/store/apps/details?id=org.ab.x48&hl=...

  Most of the point is the button-feel, though. If I'm just gonna use a computer, I might as well use a full REPL.

    Running something like Julia in Termux is possible, but not a trivial install process. =3

    I use hp48 app on the iPhone. Obviously it does not have the tactile feedback of the original. But it’s a far cry from using on a desktop with a mouse. Using a REPL as a replacement does not mimic the experience, I don’t think. Not for me at least. Mind, I’m talking a generic REPL. Like a CL REPL or similar, obviously not some custom calculator REPL. First off, you’re missing the stack, which is significant. CL can almost mimic this with , *, and *. But while it provides a free, handy value store, it’s not the same. You’d end up with contrivances like: (* * **) Then there’s the value of the special keys (i.e. SIN et al, gives a new feeling to the term “function key”). So, for me, a calculator and its hand held form factor, especially something like the high end HPs, go hand in hand. No doubt someone could (and likely has) code up a dedicated calculating experience, but a generic REPL I find to be unsuccessful in that role.

      If you want to use a REPL as a pleasant calculator you really want an APL-family language or a modern concatenative language like Factor. Sexprs are horrendously verbose in comparison.

      ‘dc’ has been a thing on Unix forever. It uses RPN, provides arbitrary precision arithmetic, and is programmable. https://en.wikipedia.org/wiki/Dc_%28computer_program%29 https://en.wikipedia.org/wiki/Dc_%28computer_program%29

  I have a physical 48GX, a 50G,a 12C and even an LX200, but I always wanted a 16C. The physical one, just because I kinda dig HP calculators.
