OSX HP48 Emulators

I recently brushed the dust off my trusty HP48SX calculator I used in college.  Back in 1991 it was my prized possession.  After all these years stuck in my desk drawer at work, it still works great.  I'm still blown away at how much it can do.

Unfortunately, it is not a calculator I want to carry around with me (you would need really big pockets).  Luckily there is a great free version of the HP48GX available for iOS: m48  This does so much more than 99% of the paid calculators available (not to mention nice extras like unit conversion, loan amortization, etc).

After spending some time rediscovering how to use the dang thing, I wanted to maximize my investment and use the equivalent on my desktop machine.  Unfortunately, it doesn't look like there is much available, other than a paid version in the AppStore.

However, I was able to get the x48 0.6.4 emulator compiled for OSX.  The only drawback is that it requires XQuartz/X11 to be installed (no longer default with Mountain Lion).  I also bundled the app with Platypus which works great.

Here's a screenshot with an extra memory card installed (see the readme/docs for instructions).

So, without further ado, you can grab the binary or the source.

Have fun!


  1. Very nice, finally I can run this emulator again on recent OS X systems! Thank you!

  2. great job!
    very hard to find a version for Yosemite.

  3. Hi there, I grabbed the binary, but it does not run on my macOS Sierra 10.12.3 - can you give me some advise? Greetings Michael

  4. Is anyone still maintaining x48 here ? I would like to at least try recompiling (currently using 10.13.4), but not seeing any xcode config in src. Thanks ! --Mark
