The programmer's calculator that defined an era — now in your pocket. my16C brings the legendary 16C Voyager series programmer's calculator back to life with cycle-accurate emulation running the original microcode. Every keystroke, every display flicker, every RPN operation — faithfully reproduced. WHY PROGRAMMERS LOVE THE 16C The 16C wasn't just a calculator — it was the essential tool for every serious programmer and computer engineer in the 1980s. Its unique combination of base conversions, bit manipulation, and RPN logic made it indispensable. Decades later, it remains unmatched. FEATURES • Cycle-accurate emulation — runs the original Voyager microcode, not a simulation • Full base conversion — HEX, DEC, OCT, and BIN at the press of a key • Bit operations — shifts, rotates, AND, OR, XOR, NOT, 1's and 2's complement • RPN entry — the efficient Reverse Polish Notation stack system • Programmable — write, store, and run programs just like the original • Authentic 7-segment LCD display with all original annunciators • Word size control (WSIZE) — work with 8, 16, 32, or 64-bit integers • Floating point mode for standard calculations • Unsigned and signed arithmetic modes 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 TRY BEFORE YOU BUY my16C includes a free trial period so you can experience the full calculator before purchasing. A single one-time purchase unlocks the app forever — no subscriptions. Whether you're a software engineer debugging hex values, a retro computing enthusiast, or someone who remembers the original on their desk — my16C is the most authentic way to use the legendary 16C today.

Very nice if you have Tahoe

Unfortunately I’m not going to upgrade my regular computer to Tahoe for this app - Tahoe has too many other issues, particularly from a developer perspective. Also, I have a separate numeric keypad connected to the computer (a KisNT KN 34) and this calculator doesn’t seem to receive keystrokes from it

You can now switch between period and comma as the decimal separator, just like on the original calculator. Turn off the calculator, press and hold the decimal point key, then tap ON. The radix mark and digit separator will swap instantly. Also fixed: display annunciator labels now match the original HP hardware.
