From the developer:
This application is an HP48 calculator emulator based on Emu48. The emulator adopts Aqua conventions such as sheets. Drag and drop is functional, and you can drag a saved stack object from the Finder to the calculator to push it onto the stack, or drag a text object (string) to the Finder to save as a text clipping.
