The existing HP-50G emulator skins are starting to look dated, so I made a new one. I made a modern flat interface, improved the keyboard shortcuts, increased the screen size, changed the screen's usual ugly green colour, and now it's my favourite mathematical tool. And it's free. And it's faster than WolframAlpha.

Open the Calculator folder and run Emu48.exe. When prompted for a KML script, select Flat HP-50G (Wide) or Flat HP-50G (Tall). After the emulator opens, you may choose to load my prefered settings by going to File > Open > settings.E49. Then just hold down CAPS and type to enter commands like a command-line application.
