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
