It was a "do all" calculator that included algebraic solver like the HP-18C, statistical, probability and time/value of money calculations. It had approximately 7 kilobytes of programmable memory which could be used for formulas or notes. The two-push 6-key letter typing system was fairly fast after a learning period. [5] HP-28C: 1987
The HP-45 is the second scientific pocket calculator introduced by Hewlett-Packard, adding to the features of the HP-35. It was introduced in 1973 [1] with an MSRP of US$395 [2] (equivalent to $2,711 in 2023). [3] Especially noteworthy was its pioneering addition of a shift key that gave other keys alternate functions.
The HP-65 is the first magnetic card-programmable handheld calculator. Introduced by Hewlett-Packard in 1974 at an MSRP of $795 [1] (equivalent to $4,912 in 2023) [2], it featured nine storage registers and room for 100 keystroke instructions. It also included a magnetic card reader/writer to save and load programs.
The HP-67 is a magnetic card-programmable handheld calculator, introduced by Hewlett-Packard in 1976 at an MSRP of $450. [1] A desktop version with built-in thermal printer was sold as the HP-97 at a price of $750. [2] Collectively, they are known as the HP-67/97. [3]
The HP-35 was 5.8 inches (150 mm) long and 3.2 inches (81 mm) wide, said to have been designed to fit into one of William Hewlett's shirt pockets. Was the first scientific calculator to fly in space in 1973. [5] HP-35 calculators were carried on the Skylab 3 and Skylab 4 flights, between July 1973 and February 1974. [6]
A graphing calculator is a class of hand-held calculator that is capable of plotting graphs and solving complex functions. While there are several companies that manufacture models of graphing calculators, Hewlett-Packard is a major manufacturer. The following table compares general and technical information for Hewlett-Packard graphing ...
The HP-28C and HP-28S were two graphing calculators produced by Hewlett-Packard from 1986 to 1992. The HP-28C was the first handheld calculator capable of solving equations symbolically. They were replaced by the HP 48 series of calculators, which grew from the menu-driven RPL programming language interface first introduced in these HP-28 series.
The HP-22S is an electronic calculator from the Hewlett-Packard company which is algebraic and scientific. This calculator is comparable to the HP-32S. A solver was included instead of programming. It had the same constraints as the 32S, lacking enough RAM for serious use. Functions available include TVM and unit conversions.
