  HP12c+ Financial Calculator Emulator
  
  The HP12c+ Emulator faithfully reproduces all the functions of the legendary HP12c financial calculator — including full programmability. Perform every financial calculation you need: TVM, IRR, NPV, bonds, calendar operations, and more.
  
  Just like the original, the HP12c+ uses Reverse Polish Notation (RPN) with a 4-level stack, 400 program steps, dedicated financial registers, and 20 memory registers. It supports percentage, statistical, linear regression, calendar, depreciation, bond pricing and yield, and cash flow discounting functions.
  Programming includes conditional branching and looping, with the ability to store and manage multiple programs. Built-in applications cover yield analysis, loans, amortization, securities, leasing, and banking operations.
  
  Additional Features in HP12c+, Interest conversion: nominal and effective; cost, price, and margin calculations; tax and base amount computations (base, tax, tax-included)
  
  This version also preserves stored programs and allows you to export them to disk f+* and reimport them f+/ later.
  
  Quick Access. Launch in popup mode with Alt + Q. If it doesn’t open automatically after installation, go to Extensions, Keyboard shortcuts, Open HP12c Calculator and set Alt+Q manually.
  
  Display Size. Switch between large and small calculator views using f++ or f+–. Your preferred size is saved for future sessions.
