About my11c
The scientific calculator that defined an era — now in your pocket. my11C brings the legendary 11C Voyager series scientific calculator back to life with cycle-accurate emulation running the original microcode. Every keystroke, every display flicker, every RPN operation — faithfully reproduced. WHY ENGINEERS LOVED THE 11C The 11C wasn't just a calculator — it was the trusted companion of engineers, scientists, and students throughout the 1980s. Its blend of powerful scientific functions, full programmability, and the legendary efficiency of RPN made it a desk-and-pocket classic. Decades later, it remains a benchmark of how a calculator should feel. FEATURES - Cycle-accurate emulation — runs the original Voyager microcode, not a simulation - Full RPN entry — the efficient Reverse Polish Notation 4-level stack - Programmable — write, store, edit, and run programs just like the original (up to 203 lines) - Complete scientific function set — trigonometric and inverse trig in DEG, RAD, and GRAD - Logarithms and exponentials — LN, LOG, e^x, 10^x - Powers, roots, reciprocals, factorial, and percentages - Statistics — mean, standard deviation, and linear regression - Permutations and combinations - Random number generator - Rectangular to polar coordinate conversion - Hours-minutes-seconds conversions - Display formatting — FIX, SCI, and ENG notation - Conditional tests and flags for real programming - Authentic 7-segment LCD display with all original annunciators BUILT FOR TODAY - iCloud sync — your calculator state follows you across devices - Native on iPhone and Mac — landscape optimized on iOS, resizable window on macOS - Full keyboard support on Mac — type numbers and operators directly - Dark interface faithful to the original Voyager design - Built-in Owner's Manual for quick reference
What’s new
Version 1.0.4 · Updated September 30, 2026
Program files • Import Program… and Export Program… – a document icon on the bezel, between Settings and the handbook (File menu on the Mac). Save the program in memory to a file, share it, and load it again later. • Files are plain-text listings with the keycodes the calculator shows in Program mode, so they can be read and typed in any text editor. JRPN 11C listings load as they are. • A file can carry a title, the author, a description of each label, notes, and the modes the program was written for (DEG/RAD/GRD, User mode, flags 0–1). Import shows everything in a preview first and can set the modes for you. • A new Program Files chapter in the handbook describes the file format. Handbook • Find in the handbook: ⌘F on the Mac, the magnifier in the toolbar on iPhone and iPad. Fixes • The trial period is now counted correctly on every launch.
