Excellent HP RPN emulation
I am a bit of an RPN calculator junkie and this incarnation of a venerable model is EXCELLENT in my opinion. The emulation seems complete, the programs run quickly, and there is a very useful ability to load and save programs. It works in landscape and upright mode.
Manuals for this model are available at the on-line HP museum and the examples there work well in this emulation. I have several calculators loaded on my iPhone - this is the one I keep for immediate access.
