The functionality in the base version lagged behind the top models of the precursor series. The alphanumeric capabilities can also be used for programming ( in FOCAL ), so that inputs and outputs can be commented on in plain text. Partial Expansion modules templates are included as keyboard overlays. This enables it to the commands which he often takes place on the keyboard. In a separate "User" mode, the user can assign these functions to each key.

Other functions can be called by entering the function name.įor this, the keyboard in the alpha mode is switched, so that each letter of the alphabet can be entered ( plus some special characters).In standard mode, each key has only two functions.Since the abundance of functions could not be meaningfully placed on the keyboard, the following three-step approach was used: The HP -41C was the first pocket calculator with programmable keys. 9.1 Technical specifications of the HP -42S.Successors were functionally very similar to the HP-42S and the much more advanced models HP -28 and HP- 48th Key differentiators over the competition by Texas Instruments ( specifically the TI- 59) and compared with Casio devices were the great expansion options and the HP typical input by means of reverse Polish notation. The three models differed in appearance only in small details and the model designation, especially the key assignment and its label were identical. The later models HP- 41CV and HP- 41CX were better equipped and also lend themselves to automatic control and data acquisition for smaller laboratory experiments through the IEC bus, which was often used. The calculators were also modular and expandable with additional Daten-/Programmspeicher, program modules, and various peripheral devices such as magnetic stripe reader, a special reader for barcodes to read programs and data, printers and tape drive. They offered alongside extensive programming and expansion opportunities, especially as the first device of this type an alphanumeric display with energy saving compared to the then usual LED indicators liquid crystals. The computers developed in spite of their relatively high prices (from 750 DM, according to today's purchasing power about 840 Euros ) quickly become an essential tool for scientists, engineers and students.

The first model of the 41er series was launched in 1979, ended in 1990, production of the series. The HP -41C and the HP- 41CV models developed and CX were programmable calculators by Hewlett -Packard.
