The programmer's calculator that defined an era โ€” 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 โ€” faithfully reproduced. WHY PROGRAMMERS LOVE THE 16C The 16C wasn't just a calculator โ€” 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 โ€ข Cycle-accurate emulation โ€” runs the original Voyager microcode, not a simulation โ€ข Full base conversion โ€” HEX, DEC, OCT, and BIN at the press of a key โ€ข Bit operations โ€” shifts, rotates, AND, OR, XOR, NOT, 1's and 2's complement โ€ข RPN entry โ€” the efficient Reverse Polish Notation stack system โ€ข Programmable โ€” write, store, and run programs just like the original โ€ข Authentic 7-segment LCD display with all original annunciators โ€ข Word size control (WSIZE) โ€” work with 8, 16, 32, or 64-bit integers โ€ข Floating point mode for standard calculations โ€ข Unsigned and signed arithmetic modes BUILT FOR TODAY โ€ข iCloud sync โ€” your calculator state follows you across devices โ€ข Native on iPhone and Mac โ€” landscape optimized on iOS, resizable window on macOS โ€ข Full keyboard support on Mac โ€” type numbers and operators directly โ€ข Dark interface faithful to the original Voyager design โ€ข 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 โ€” no subscriptions.
