i41CX+ is an advanced programmable and expandable RPN scientific calculator with a virtual thermal printer/plotter. i41CX+ is functionally equivalent to the world-renowned HP-41CX and supports over 200 built-in functions and contains 319 registers of main memory for storing data, programs, alarms, and user-defined key assignments. It also contains 600 extended memory registers for storage of data, text, and program files. The large number of registers combined with programmability, makes the 41CX+ an extremely powerful scientific calculator suitable for a wide variety of scientific, engineering, mathematical, financial, and technical applications.

• RPN logic with a 4 element deep memory stack
• Powerful and rich set of numerical, mathematical, and statistical functions

The virtual thermal printer/plotter supports printing, plotting, graphics, and special characters. The printer has three basic modes of operation. In manual mode the printer only prints when explicitly specified to do so by either the user or a program. In normal mode, the printer prints numbers and alphanumeric characters that are entered by the user, function names as they are executed from the keyboard, and output from print functions. In trace mode, the printer prints numbers and alphanumeric that are entered by the user, function names, intermediate and final answers, and output from print functions.

• Ability to control print color on a per line basis either via GUI color sliders or programmatically via the calculator’s highest numbered data register
• The state of the printer/plotter is retained across program launches
• Ability to save a JPEG snapshot of the virtual paper roll to the iPhone’s photo gallery. These can then be emailed or transferred to the computer and printed out on a real printer.

******* NOTE TO 1G iPOD TOUCH USERS *******
Sounds, including the key click sound, are only audible when played back through the headphones. To mitigate this limitation, i41CX+ supports an option to enable a “glow” key press feedback effect.
