There are a number of Windows-based calculator emulators out there which try to look and behave like various HP models. For the last few years I have used Excalibur for Windows. It doesn't try to look like anything else, which for me is fine, and it does everything I ask of an RPN calculator. It is an amazing piece of freeware and the developer is definitely one of the good guys.
