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
