Description |

Free42 | Free42, a cross platform emulator, is a complete re-implementation of the HP-42S calculator and the HP-82240 printer. Free42 was written from scratch, without using any HP code. You do not need any ROM images in order to use it, yet it is fully HP-42S compatible. |

HP 9100A Emulator | This emulates exactly what it says it does. |

Nonpareil | Nonpareil is a high-fidelity simulator for calculators. It currently supports many HP calculators models introduced between 1972 and 1982. Simulation fidelity is achieved through the use of the actual microcode of the calculators, thus in most cases the simulation behavior exactly matches that of the real calculator. In particular, numerical results will be identical, because the simulator is using the BCD arithmetic algorithms from the calculator. |

nsim | nsim is a microcode-level simulator for the HP-41CV programmable scientific calculator. It is written in C and uses the X window system for display. |
