Clever and useful
One of my favorite RPN calculators. Good looks, simple display basically shows X-register, but entire contents of stack and memory are easily accessible. Easy to program, with comprehensive instructions built in. Has a relatively light memory footprint, good for devices that are short on memory. Keyboard is a little disconcerting at first because it doesn't appear to have an enter key, but it's there - it's just labeled X with an up-arrow next to it. A little different from traditional RPN calculators but fun to use and all the same functionality is there.
Interesting reproduction of original
I bought this app and own several real MK-61 calculators and an MK-52. This is a very good reproduction, albeit in English. Some things that I notice right away are that the red Clear button on my real MK-61 is Cx, which clears all the way F-C on this app behaves. Also the addition of Bin Hex and Dec features on this app. I wonder if there was a version of the original calculator that had these features (which makes the app a little nicer to use). Anyway this is a very cool app. Thanks!
The best RPN calculator!
Thank you! If you make MK-52 I'll buy without hesitations!
