HPN is a functional - as opposed to microcode - cross-platform emulation of a classic 1970s Hewlett-Packard scientific calculator for any command-line interface. Its operations completely model the historical and groundbreaking HP-35 series, and functions to support the HP-45 and the later HP-65, 67 and HP-15C are in the pipeline.
Features
- Faithfully models all the operations of the HP-35 calculator
- Complete inline help is available
- Described by Softpedia as "lightweight and intuitive"
- Tested to compile under Linux and Windows
- Will compile for other *nix platforms, including Mac (not tested)
- Windows and Linux binaries are included in the source package
- Package includes the original HP-35 User's Handbook as a PDF

I'm using the Windows version - it runs fine and is fun to use ! Thank you very much and goodbye to brackets. Keyboard usage is very concise, eg t = tan, but this could be an issue with typos - maybe it should expand letter keys after enter is pressed eg t to tan. Maybe I'm missing something fundamental, but would like to see units support (eg degrees, radians) - apparently the HP35s has a mode button ? Also additional functions like hyperbolics / stats but maybe they are in the works with the other emulations you plan. I'm not sure about being so tightly bound to emulating the calculators, on the other hand I'm sure a lot of thought went into their "user interface" and the original HP documentation is a bonus ! Cheers.

I don't know what platform or version pmancer was trying to compile on, but the latest snapshot of hpn includes all the necessary Pascal files, along with working Linux and Windows binaries for convenience. Compile and run have been thoroughly tested under Linux (Ubuntu/Mint) and Windows (XP). Softpedia, where hpn is also listed, has no complaints about the program, describing hpn as "lightweight and intuitive". Development will continue, so all comments are welcome.

Don't waste your time downloading. The source is missing files so you can't compile and there are no provided binaries!!
