Retired Old User
Before buying check the web for more credible reviews, I found lots. RPN is really addictive after using it and although I dont crank out the math I used to this app feels just like an old friend reincarnate. Still have my original calculator with the instructions which should work fine with this app. I love it. Paid a lot of money for the original calc and more for the plug in chips. In 2014 dollars this costs squat! One wish, let me paste in numbers Ive copied from other sources. Its not original but this is the computer age.
