![]() Unfortunately there is no way to export programs/data/memory, although, if I could only keep one calculator, this would certainly be the one (that is until the arrival of the Swiss Micros DM42), and therefore I rate it 5 stars. The display can also be used for graphics. Many scientists and engineers still use this calculator today. ![]() This calculator is often regarded as the best ever made in terms of quality, key stroke feel, ease of programming, and daily usability for engineers. ![]() I just wanted to demonstrate its' graphing capability with this video. HP 42S RPN Scientific Calculator w/ HP-15C plus. The dot-matrix screen resolution and contrast is sub-par. HP 42S is largely known to be a two line Scientific RPN Calculator. * Simple but powerful RPN keystroke programming methodĪlthough there are certain design features that do not compare favorably to my other HP calculators: * User-assigned Alpha-character program labels and variables and numbered registers makes this a very nice programmable. * Plenty of program storage capacity (~7kB) I prefer it to single line for the added context when programming or caculating, and of course navigating menus. The complex number support is thorough, takes up a single stack register, and is very nicely implemented. The quality (feel and reliability) of the button presses (again, second only to the HP Voyager line). Due to the number of functions and capability available, much is accessible via a menu system, for a clean UI look and operation. Compact size (truly shirt pocketable, second only to the HP Voyager line such as HP12c and 15c). UPC 088698000311 is associated with product Hp-42s Rpn Scientific Calculator With Case, Manual, & Box - Vintage, find 088698000311 barcode image. I reach for this calculator whenever I actually need to use the advanced features such as complex number calculations or a custom program, There is also an excellent digital version of this calculator available as a smartphone App (Free42, developed by Thomas Okken). I prefer older HP calculators due to RPN and superior build quality.Īlthough not my favorite EDC for banging out quick calculations (HP 32sii for that), it is by far the most powerful and trustworthy pocket calculator that I have ever owned and coupled with ease of use (due to well thought-out UI), excellent build quality (but not quite as good as the HP Voyager series), and great size/form factor, makes it technically my favorite pocket scientific calculator. For questions about me and the origin of the museum, please see my personal page.I have a small collection (~20) of calculators, most of them being 80/90s era HP handhelds.
