Nonpareil is a microcode-level simulator for electronic
calculators. The software simulates some of the HP
calculators introduced between 1972 and 1982.
Simulation fidelity is achieved through the use of the actual
microcode of the calculators. Consequently, 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.
Nonpareil attempts to run the simulation at the same nominal
rate of microinstruction execution as a real calculator, e.g., 3500
microinstructions per second for an HP-55.
- Simulates the following calculators:

- HP-21, HP-25
- HP-31E, HP-33C, HP-34C, HP-37E, HP-38E, HP-38C
- HP-41CV, HP-41CX
- Simulates an 82143A printer
