- JRPN 16C and 15C are calculator simulators inspired by HP's 1982 models.
- The simulators mimic the original calculators' functionality and appearance without using HP's source code.
- User guides for the simulators are based on the original HP Owner's Handbooks.
- The UI scales to any screen size without pixelization, using graphics primitives.
- The project started as a hobby, with no revenue, and is open-source with a permissive license.
- JRPN was rewritten during COVID using Flutter for a more authentic UI experience.
- The web version works but has limitations; primary support is for desktop and mobile platforms.
- iOS distribution is hindered by Apple's developer program requirements.
- The software is provided 'AS IS' without any warranties.
