Its a good program, but there is an implementation error. If I remember well, the 48's delete button delets only the first number in the stack. If you are entering numbers the delete button should only delete the last digit. In this implementation the whole stack is erased when the delete button is pressed. Needs more work as others have mentionned. The 48 is my favourite calculator and will definetly use this program when its ready. Ah, should definetly be renamed. I also had the problem where my other RPN calculator program was erased and replaced by this one when I installed it.

Warning, missing PI (key), otherwise ok. Would be nice to take input from memo so long formulas could be saved and edited more easily (long sequences are always error prone). It did convince me to write my own, palm's are much better than scientific calculators. :)

Very good. I downloaded the special version for OS 3.3. Drawback: no way to convert easily decimal degrees into deg min seconds.

A good free RPN calculator is a good idea. However, my experience with this one was not good. When I entered a number with two digits past the decimal place (hundreths) it reverses the digits. For instance, I type 2.25 then hit the "enter" button and in register 1 what shows up is 2.52. Needs more work.

Great to have a freeware palm program, but I have some issues. Not sure why it was modelled against the HP48 - since there are problems with the design. Enter button should be on the right, so should the main buttons - since on a palm most people use the stylus R-handed. Silly to call it RPN.prc, since so many RPNs do that - and I lost my main one! Needs a "last x" button, for reversing the last calculation. Would be useful if it had memory registers (drag&drop to and from digits).
