cs-41 RPN calculator is a remake of the amazing HP-41C/CV series of Hewlett-Packard RPN programmable calculators. It contains near all the built-in functions found in the original HP-41C (including sounds) and the ability to save and restore ilimited programs in "module" files, so you can modify routines, start new ones, erase the calculator's memory, quit and reopen the app without worry - the saved modules will remain intact to be restored when you need them.
Note: Now requires OS X 10.9 or later
- Fixed an issue that prevented to reset the memory or load module files under OS X 10.10 Yosemite
- A few improvements in the appearance
- OS X 10.9 or later
