Features of the real HP-15C

The HP-15C was a high end scientific programmable calculator and the top model of the Voyager series. Some of the main features are:

• RPN logic with 4 stack levels plus a last X (LSTx) register.
• 67 addressable registers, used for storage registers or program steps.
• 19 storage registers in default configuration with 46 registers for programs (appx. 332 program steps).
• Programmable with up to 448 program steps. In this configuration only 3 storage registers are available: R0, R1 and RI
• 10 Flags and 12 conditional tests, such as x = 0, x ≠ 0 and x > y.
• Indexed looping via storage gegister I.
• Full storage arithmetic: STO +, −, × and ÷.
• 5 softkeys, labeled A through E.
• Multiple number format: FIXed, SCIentific and ENGineering.
• Trigonometric functions SIN, COS and TAN.
• Hyperbolic trigonometric functions SINH, COSH TANH.
• Three trigonometric modes: DEGrees, RADians and GRADs.
• Reverse trigonometric functions for standard and hyperbolic functions.
• Mean and standard deviation of 2 variables.
• Summation of n, x, x², y, y² and xy for statistic calculations of 2 variables.
• Decimal hours and hrs.min.sec. conversions.
• Polar and rectangular conversions.
• Solve and root finder.
• Numeric integration.
• Linear regression.
• Complex numbers.
• Continuous memory.

The real HP-15C also provides Matrix operations. These are not implemented in the simulator.
A more detailed feature list is available from the HP Calculator Museum.

Additional Features of the Simulator

Additional features provided by the simulator to integrate with and benefit from the operating system.

• NEW: Data exchange with the DM-15/DM-15CC card-size HP-15C clones.
• Native support for Windows (XP and following), Mac OS X (Intel based) and Linux (x86)
• The source code version should run on all unixoid operating systems supported by Tcl/Tk 8.5.x.
• Pop-up menus for stack, storage registers, program, flags and conditional tests.
• Save and load programs to and from disk.
• Programs can be documented, the documentation is stored with the program file.
• Export a program and its documentation as HTML file.
• Integration with the operating system's clipboard.
• Code and mnenomic display of program steps (via pop-up menu).
• Full mouse and keyboard support.
• Multi language support for pop-up menus and dialogues.
