Leave a Review Legendary 67
Looks good but sounds terrible
I like the look and functionality of the calculator but the sound of the button click is not in line with the calculator look and feel. Wish it was closer to the sound of the actual calculator buttons which was one of the outstanding features of the typical HP calculator.raytttat

Thank you for the review. The sounds are actual recordings of an original hp 67. However, as the original is already quite dated (especially the magnet card drive), the sounds might not be the same anymore. Also, the recordings probably cannot capture the true sound. You can disable the sound in the settings or after pressing h E.RPN!!! It has Reversed Polish Notation
The first calculator I used with any frequency was a HP 46. Before that was a slide rule. HP used to always make the best calculators. Then I got issued a HP 67. That’s where I first got into programming, and eventually became a real computer programmer.
Anyway, as far as I can tell, this is a nearly flawless implementation of one of absolutely best hardware calculators ever.
But pardon me for asking for support, is there documentation somewhere in the program?
Oh, for those who aren’t familiar with Reverse Polish Notation, (not a slur, it was invented by a Polish guy), and if you do much more than add - subtract, multiply, divide, you owe it to yourself to learn RPN well enough to make a judgement. As an ex-land surveyor, math guy and programmer, I can tell you that it’s worth learning. It’s much more flexible than algebraic notation.Show lessRussJones67220
This is a great app
I used a real HP-67 when I was studying statistics at university. I still pwe a working one. This app is as close to the real thing ss it can get. Great work Fabian!ndc1954usa
