A high-fidelity simulator for calculators

Nonpareil simulates 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.

Nonpareil was written by Eric Smith and contributors, and simulates the following calculator models:

  • 21 Scientific Calculator
  • 25 Programmable Scientific Calculator
  • 32E Scientific Calculator
  • 33C Programmable Scientific Calculator
  • 34C Programmable Scientific Calculator
  • 35 Scientific Calculator
  • 37E Financial Calculator
  • 38C Programmable Financial Calculator
  • 38E Programmable Financial Calculator
  • 41CV Programmable Scientific Calculator
  • 41CX Programmable Scientific Calculator
  • 45 Advanced Scientific Calculator
  • 55 Programmable Scientific Calculator
  • 80 Business Calculator
