a41cv is my open source simulator of the legendary HP41CV RPN calculator. The first production version of a41cv was released in February 2011. Nearly all of the original HP41CV functions are implemented.
The calculator differs from the HP41CV in the following ways:
No definition of number of register
Programmes cannot be assigned to keys (working on that)
Not all special flags implemented
Number of programme lines only limited by phone memory
Only a simple programme editor (by now) but full import / export of programmes on cvs format
Still trying to make a41CV fit better on the now more than 1782 different devices it works on according to Google Market

Recently changed in this version

Not much news in version 1.5.
Some bugs have been solved and the old layout removed as it was too dependent on screen size. This reduced the size of the app to a 1/4 of last version.
Bug fixes:
Problem with rounding in INT function solved
Problem with stack lost when the user switch to other apps solved

    Ugly GUI and pgm mode crashes every time. Display too small.

    Thanks a million! I thought I would never see my old hp41CV ever again. And here it is right here on my favorite phone. Runs great on RAZR Maxx and droid Maxx

    The HP41CV was THE calculator in the early 80's. Thank you for making this app, seeing it brought alive like this made me a little emotional. Thank you and keep up the good work!

    This really is the closest to the real thing. I use it all the time at work. No need to carry a scientific calculator around for with me any longer. Give it a try.
