Not simulations — cycle-accurate microcode emulation of the actual hardware that defined an era. Seven legendary programmable calculators, faithfully reproduced for iPhone, iPad, and Mac.
HP-41 Emulator
The expandable, modular flagship of HP's programmable line.
TI Emulators
Texas Instruments' Programmable family — algebraic entry and Learn-mode keystroke programming.
Texas Instruments TI-59
The most accurate TI-59 programmable calculator emulator available — built on cycle-accurate microcode emulation.
Open →Texas Instruments TI-57
Microcode-level emulation of the TI-57 — 50 program steps, 8 memory registers, and Learn-mode programming with branches and subroutines.
Open →HP Voyager Emulators
The shirt-pocket RPN calculators that defined a generation of engineers — and of financiers.
HP-16C Computer Scientist
Microcode-level emulation of the Voyager-series HP-16C — the calculator built specifically for programmers. HEX, OCT, BIN, bit ops, all of it.
Open →HP-11C Programmable Scientific
Microcode-level emulation of the Voyager-series HP-11C — the everyday RPN scientific with trig, statistics, linear regression, and keystroke programming.
Open →HP-12C Financial
Microcode-level emulation of the Voyager-series HP-12C — the financial legend still in production today. Time value of money, amortization, NPV and IRR, bonds, and depreciation.
Open →HP-15C Advanced Scientific
Microcode-level emulation of the Voyager-series HP-15C — matrices, complex numbers, numerical integration, and root solving. Widely regarded as the finest scientific calculator ever made.
