Have you tried HP's one? I thought it might also just emulate the hardware and run the actual HP-15c ROM, but it's hard to be sure. The MEM function (and everything else I've tried) certainly seems to work. How do I perform the "Forensic Test"?

Execute the following equation:
arcsin (arccos (arctan (tan (cos (sin (9) ) ) ) ) )

For more information on calculator forensics and the results from various calculator models, see the following site.

And yes, I would expect HP's app to be using the original HP-15C firmware so it should have the same result as a real HP-15C. In this case the result should be 9.000417403.
