The HP41c calculator, produced from 1979 until 1990, was the standard in engineering and sciences during most of its life. Programmable, alphanumeric, with a high contrast LCD screen, and expandable, it was a true computer in your pocket. Here is our web hommage to it.
Its capabilities could be extended by means of ROM modules with additional functions, and with interfaces it could use printers, plotters, mass storage devices, bar code readers, measurement instruments, etc.
Recently, the user community has developed both new software in ROMs (like the Sandmath family) and hardware: a circuit that substitutes the original and throroughly updates the calculator in terms of speed, memory and functions, including all known modules ever developed (the HP41CL from Monte Dalrymple)
