From its introduction in 1979 until final production in 1990, the Hewlett Packard 41 Series Programmable Calculator reigned supreme as the trusted companion of professionals and students worldwide. Its instant success was due to innovation, quality and a well established base of loyal customers.

The HP-41 series calculators were very successful. The HP-41C was produced from 1979 to 1985, the HP-41CV was produced from 1980 to 1990, and the HP-41CX was produced from 1983 to 1990. "At least 1.5 million HP-41 units of all types were sold - perhaps more" [1]

2021年2月12日 · The full nut version was the original design of the calculator. After a while, the calculators were redesigned and simplified, and this is how the “half nut” (halfnut) version appeared. The HP-41C exists in only one version: the so-called “full nut” (or fullnut). The HP-41CV and CX exists in both full nut and half nut versions.

The Systemyde 41CL takes advantage of modern technology to significantly add to the capabilities of the Hewlett-Packard 41C system. The 41CL circuit board replaces the original CPU board in the calculator and provides all the features of an HP-41CX except for the Time Module.
