Notes:	The HP 41C series must be the top-of-the-bill calculator design of all time. It’s the successor to the HP 67. Even today this calculator is still totally up-to-date and usable. It’s my all-time favourite series of calculators. The HP 41C series has three models, here in chronological order: HP 41C (this one) HP 41CV HP 41CX Working on the text, please wait. Time to be more elaborate about this series. It has constant memory and has four extension possibilities. The case is wonderful and, well, only HP could build them like this. The HP 41C (which was introduced in 1979) was probably the first alphanumeric handheld calculator ever. It was far before dot-matrix LCD’s existed, and it uses a clever display using 14 segments. Programming this calculator is more difficult than necessary however (at least compared to more modern programmable calculators, but at the time the programming of the HP 41 was a huge step forward). It’s therefore not my favourite of programmable calculators (that is the CASIO FX-602P if you want to know). The HP 41 series calculators have had a very long lifetime. The range of peripherals is also amazing. For more information on this beauty please refer to the better sources, like The Museum of HP Calculators (link validated 2024-01-13).

Peripherals

There many peripherals available for this calculator.

The HP 41C has four easily accessible extension slots which can be used for ROM modules, a clock module, a HP-IL connection, card reader, printer, even an HP 67 compatible card reader which translates HP 67 programs to HP 41C programs on the fly. The only peripherals I own myself are the HP 82143A Peripheral Printer and the 82104A Card Reader.
