## What is my10c?

my10c brings the Voyager Series model 10C back to life — not as a look-alike, but as a true microcode-level emulation. The app runs the original 10C ROM on a cycle-accurate model of the Nut processor, so every calculation, every rounding, every display quirk and every undocumented behavior is exactly what the real calculator did in 1982.

• RPN entry with the four-level stack, LAST X and ten storage registers
• Trigonometric functions and inverses in degrees, radians and grads
• Logarithms, exponentials, powers, square root, reciprocal and factorial
• Polar–rectangular, hours–minutes–seconds and degrees–radians conversions
• Two-variable statistics: mean, standard deviation, linear regression and estimation
• FIX, SCI and ENG display modes
• 79 lines of keystroke programming with GTO branches, x≤y and x=0 tests, PSE and single-step execution
• Continuous memory: programs and registers survive quitting the app
• The original self-tests, including the keyboard test

PROGRAM FILES
Save the program in memory to a text file and load it again later. Files carry a title, author, notes and the mode the program was written for, and the listing uses the keycodes the calculator itself shows, so programs can be read and typed in any text editor and shared with other users.

THE ORIGINAL HANDBOOK, BUILT IN
The complete Owner's Handbook and Problem-Solving Guide is included, rewritten for the app page by page, with every example and worked program, searchable, and with the display readouts drawn as the calculator shows them.

MADE FOR APPLE PLATFORMS
• One purchase for iPhone, iPad and Mac
• Landscape layout that fills the screen on every device
• On the Mac: keyboard typing, a resizable window and an optional menu bar mode that keeps the calculator one click away
• Real-speed emulation of the original hardware, or turbo mode when you want results instantly
• Sound and haptic feedback on iOS
• Your calculator state follows you between devices with iCloud

my10c is part of a family of microcode emulators from Nibble Workshop: my11c, my12c, my15c and my16c complete the Voyager series, alongside my41cx, my59 and my57.
