HP42 calculator on your smartphone

    A friend showed this to me today, and I downloaded it and am loving it. The HP42 was my favorite calculator, and after my latest one died many years ago, I hadn't been able to find any to buy (at a reasonable price). But now there is a free app that you can download to your phone that brings your trusty HP42 back to life! I'm a happy camper. :biggrin:

    Get the app "Free42" from your apps store, or visit the developer's website here: http://thomasokken.com/

    That’s cool, @berkeman! I once used a really old one of those that I found in the garage and I was planning to use it for my schoolwork, but the screen was all faded and the calculator leaked ink. So I got a new TI calc to replace it.

    I’ll definitely download this, though!

    I'm a big fan of RPN, so having my trusty HP42 back is so nice! :smile:

    So I guess I couldn't interest you with this TI?
