RPN-67 SD

Good replica of 67. I have one issue that could be quickly solved. When I press the f or g key and then the display key, and enter a 4, the number of digits does not change from 2 to 4 and I would be happy.

This was my first scientific calculator in real life. It is great to have the simulator on my iPhone. The special features added make it into a HP-41 or 42S! It comes packaged with some great samples. Am having great fun with it.

My first HP calculator was an HP 29. A few years later, I got an HP 67. Later I bought a 15C and when I started an MBA program i got a 12c. It means a lot to have a really faithful representation of my old friend. I currently have this emulator plus a 12c and 15c (from different a vendor) on my iPhone. I love them all. Take it from somebody who know, all the emulators replicate their real world counterparts.
