Nonpareil simulates many HP calculators models introduced between 1972
and 1982. Simulation fidelity is achieved through the use of the actual

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
