The Museum of HP Calculators. This small but powerful calculator was designed to be software compatible with the HPC. It lacked the HPC's expandability but it offered, a two-line dot matrix screen with customizable menus, greater speed, smaller size, and a lower price as compensation. The calculator had over built-in functions. Obviously, many of these were not printed on the keyboard but could be accessed by catalog, by typing their name after the XEQ key or by assigning them to the custom menu. Functions included:. The HPS had numbered storage registers and named variables.

It has advanced functions suitable for applications in mathematics , linear algebra , statistical analysis , computer science and others. Perhaps the HPS was to be released as a replacement for the aging HP series as it is designed to be compatible with all programs written for the HP The 42S, however, has a much smaller form factor than the 41, and features many more built-in functions, such as a matrix editor, complex number support, an equation solver , user-defined menus, and basic graphing capabilities the 42S can draw graphs only by programs. Additionally, it features a two-line dot matrix display, which made stack manipulation easier to understand. Production of the 42S ended in The HPS is keystroke-programmable , meaning that it can remember and later execute sequences of keystrokes to solve particular problems of interest to the user. The HPS supports indirect addressing with which it is possible to implement a Universal Turing machine and therefore the programming model of the HPS can be considered Turing-complete. This is a sample program which computes the factorial of an input integer number ignoring the calculator's built-in factorial function. The program consumes 18 bytes. No memory registers are used. The final product was released on the 9 December Since , Free42 version 3 and Plus42 version 1 optionally supports a dynamic RPN stack only limited by the amount of available memory instead of the classical four-level stack.

The HPS had numbered storage registers and named variables. Initially, 25 numbered registers were allocated but this number could be changed to use as much memory as the user required. Only registers numbered could be accessed directly. Higher numbers required indirect access.

Programmability see below. Complex numbers see below. The HPS supports indirect addressing with which it is possible to implement a Universal Turing machine and therefore the programming model of the HPS can be considered Turing-complete. No packaging or cables included. For instance to store the number in X in the register indicated by the value held in register 12, the user would press STO. HPS features. In other projects. I sent the DM42 back. A new feature on this model allowed both polar and rectangular forms of complex numbers. Add to List. Matrices could be stored on the stack or in variables.

Hidden category: Use dmy dates from April Variables and the stack registers could also be used for indirection so a sequence like STO. Value for money. Back to top. The HPS had numbered storage registers and named variables. I have it on display in my library beside the long dead An RPN calculator that feels fantastic to hold and use, that delivers all the functionality you could want, and that is built to last a very long time. Programming Programming was essentially the same as the HPC with the following exceptions. Menus could lead to submenus and where most Pioneers had a clear key, this model had an EXIT key to return to the previous menu. Hewlett-Packard HP calculators. It's my everything calculator. Variables were more powerful than registers because they could hold complex numbers and matrices. Learn more how customers reviews work on Amazon. Additionally, it features a two-line dot matrix display, which made stack manipulation easier to understand. The Alpha register held up to 44 characters.
