75 KB usable RAM, a beeper, a callable real-time clock as well as an infrared port for HP 82240A/HP 82240B printer support and a USB interface (with Micro-B connector) emulating a FAT16-formatted USB mass storage device for easy program transfer and state backup / transfer as well as for firmware updates. This is a sample program which computes the factorial of an input integer number (ignoring the calculator's built-in factorial function). ASTRO_TSO: calculates the fix using the standard azimuth-intercept method of Marcq St. Hilaire which is based on the calculation of the point of intersection of 2 position lines. There is no manual for Free42 per se, but since it is an accurate simulation of the HP-42S, the original HP-42S Owner's Manual should be adequate for most purposes.

Torsten Manz wrote the best desktop version of the HP-15c. I dont want to have to put in Z-scores, i can just put in mean and sd (once) and then find the upper tail or inverse. The DM42 is also the hardware basis for the community-developed WP 43S calculator,[5][6] a successor to the WP 34S. An HP 35s (top centre), with an HP-67, HP-34C, HP-41CX, and HP-42S. It is powered by a CR2032 coin cell or via USB and clocked dynamically at 24-80 MHz. The original HP-41C series and HP-42S were broader market, certainly for engineers and scientists, but not necessarily true aficionados. HP-35s This is a 2008 hp-35s. An Hp 35s seems to be designed to last 3-5 years of moderate to heavy use vs older Hp's would last for decades. They had only bulky graphing calculators in ugly metallic design. The program consumes 18 bytes. https://en.wikipedia.org/w/index.php?title=HP-42S&oldid=986999324, Creative Commons Attribution-ShareAlike License. The developers of the 34S and 43S go beyond what HP would have dared do for a broad-market product. Indeed. Well, The 35s came with a program in the manual, and its as accurate as my tables book. An Alternative: HP-42S calculator and Free42 simulator for PalmOS. 6 MB are available to users). I also recommend the Alternative HP-42S/Free42 Manual, written by José Lauro Strapasson and Russ Jones; you can get it here, in PDF and Word formats. Perhaps the HP-42S was to be released as a replacement for the aging HP-41 series as it is designed to be compatible with all programs written for the HP-41. I like it. The Hp 50G is a much more feature rich calculator, but if you liked your Hp 32sii, you will probably like the Hp 35s better than the bulkier Hp 50G.. Indeed. HP 35S 35S Programmable Scientific Calculator, 14-Digit LCD (HP-35S/B12) 4.6 out of 5 stars 667. ... My favorite aspects of the HP 42s: - Compact size (truly shirt pocketable, second only to the HP Voyager line such as HP12c and 15c). The HP-42S RPN Scientific is a programmable RPN Scientific hand held calculator introduced by Hewlett Packard in 1988. HP-42S calculator pdf manual download. Production of the 42S ended in 1995. The HP-42S supports indirect addressing with which it is possible to implement a Universal Turing machine and therefore the programming model of the HP-42S can be considered Turing-complete. Physical RPN Calculators with real buttons. The 34S and 43S are calculators designed by RPN calculator geeks for RPN calculator geeks. The final product was released on the 9 December 2017. 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). Since it lacked expandability, and lacked any real I/O ability, both key features of the HP-41 series, it was marketed as an HP-15C replacement.. I would appreciate if someone can tell me where to download the Owner's Manual in english for for my trusty HP-42S (serial number {Personal Information Removed}) because some time ago I misplaced the manual. These programs make the HP-42S (Free42) a worthy equivalent of an astrocomputer to navigate by the sun. World's Most Precise RPN Calculators. Only 18 left in stock - order soon.

This is, after many years, the first scientific RPN calculator which comes close to the successful classic RPN calculators. The calculator, which comes in a stainless steel case with matte black physical vapor deposition (PVD) coating, supports keyboard overlays and is based on a modified version of Thomas Okken's GPLed Free42 simulator with Intel's decimal floating-point math library for higher precision (decimal128) running on an STM32L476RG processor (ARM Cortex-M4 core, 128 KB RAM, 1 MB internal flash) with another 8 MB of external QSPI flash (of which ca. The HP 35s is just slightly larger in width and height than HP’s earlier pocket scientific offerings, but thanks to modern technology, quite a bit thinner. Perhaps the HP-42S was to be released as a replacement for the aging HP-41 series as it is designed to be compatible with all programs written for the HP-41. Real easy. List of Hewlett-Packard pocket calculators, http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv020.cgi?read=177373, "Upgrading the memory of the HP 42S to 32KB", "HP-42S Owner's Manual Addendum: Hidden Matrix Functions". The 34S and 43S are calculators designed by RPN calculator geeks for RPN calculator geeks. The developers of the 34S and 43S go beyond what HP would have dared do for a broad-market product. The original HP-41C series and HP-42S were broader market, certainly for engineers and scientists, but not necessarily true aficionados. The HP-42S uses a superset of the HP-41CX FOCAL language. It has advanced functions suitable for applications in mathematics, linear algebra, statistical analysis, computer science and others. While surfing the Internet I found the page HP Japan where if … View and Download HP -42S manual online. For many years HP did not produce anymore any good scientific RPN calculators. Even though slightly smaller (144×77×13 mm, 170 g) than the original HP-42S (148×80×15 mm, 170 g), the calculator comes with an additional top row of keys for soft menus, a keyboard layout supporting direct alpha character input, a much larger high-contrast display (Sharp low power transflective memory LCD with a resolution of 400×240, protected by Gorilla Glass) showing all four stack levels at once (configurable), ca. [2] As this calculator is regarded amongst the best ever made in terms of quality, key stroke feel, ease of programming, and daily usability for engineers,[3] in the HP calculator community the 42S has become famous for its high prices in online auctions, up to several times its introduction price, which has created a scarcity for utility end users.
