The HP-42S RPN Scientific is a programmable RPN Scientific hand held calculator introduced by Hewlett-Packard in 1988. It is a popular calculator designed for science and engineering students. Overview
The original TI-30 was notable for its very low cost for the time, around US$25. This was much less than the retail prices of other scientific calculators of the era; for example, Hewlett-Packard's cheapest scientific calculator at the time was still well over $100. The Casio FX-20, another popular scientific calculator, sold for roughly double ...
The HP 35s (F2215A) is a Hewlett-Packard non-graphing programmable scientific calculator. Although it is a successor to the HP 33s, it was introduced to commemorate the 35th anniversary of the HP-35, Hewlett-Packard's first pocket calculator (and the world's first pocket scientific calculator). HP also released a limited production anniversary ...
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.

SR-50 (1974) Printed circuit board. Data code 035: 3rd week 1975. The SR-50 was Texas Instruments' first scientific pocket calculator with trigonometric and logarithm functions. . It enhanced their earlier SR-10 and SR-11 calculators, introduced in 1973, which had featured scientific notation, squares, square root, and reciprocals, but had no trig or log functions, and lacked other featur
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.
Introduced by HP for students, the HP 10s (F2214A) is a scientific calculator with more than 240 built-in functions, with 2 lines x 10 digits LCD. It is permitted to use on SAT and ACT tests. [3] It has a standard scientific layout and function set that very closely correlates with the Casio fx-85MS, allowing for calculations to be done in a ...
