![]() A DM15 Silver Edition in a titanium case is available as well in three color variants (metal, brown, blue). With a modified firmware (M80 and M1B), the additional memory allows for up to 129 or even 230 registers and up to 1603 or 896 programs steps. Newer DM15 models feature a better keyboard and more RAM ( LPC1115). It closely emulates the functionality of the original HP-15C by running the original ROM image in an emulator on an ARM Cortex-M0-based NXP LPC1114 processor. On 6 February 2012, SwissMicros (previously known as RPN-Calc) introduced a miniature clone named DM-15CC approximating the size of an ID-1 credit card (88 mm × 59 mm × 7 mm). Another version is commercially available for Android and iOS devices. Īn official PC emulator for the 15C is available as freeware from Hewlett-Packard. The original manual did not include the new self-test procedure. The original HP-15C self-test keystrokes do not work with the HP-15C LE and can corrupt memory contents.Downgrading the firmware resolves the PSE bug, however, other bugs will also be reintroduced. One of the more significant bugs in the released firmware version (dated in the self-test) is that PSE only works once in a program and subsequently blanks the display until the program stops or is stopped.The non-responsive reset procedure documented in the 15C manual had the side effect of rotating the X register by 22 bits which could then be used to perform synthetic programming.This model is powered by two CR2032 batteries, and can easily be differentiated from the original model by the "Limited Edition" script below the company logo as well as the black text on brushed metal back label, as opposed to the white text on black of the original.The power consumption of the processor is greater than that of the original HP-15C, as HP did not use the same technology in any of the future models. The calculator was released alongside the HP 12c 30th Anniversary Edition. It is based on a flashable controller utilizing the same ARM7TDMI core already used in the 2008 revision of the 12C but in a different package, an Atmel AT91SAM7L128-AU running an emulator written by Cyrille de Brébisson to execute the old HP Nut code much faster than on the original hardware. HP 15c Limited Edition Īfter showing a prototype labelled " HP 15c+" at the HHC 2010, HP announced the HP 15c Limited Edition (NW250AA) on 1 September 2011. The 15C used CMOS technology for its processor, resulting in very low power consumption. The HP-15C was a replacement for the HP-34C. Although out of production, its popularity has led to high prices on the used market. The calculator is able to handle complex numbers and matrix operations. A member of Hewlett-Packard Voyager series of programmable calculators, it was produced between 19. The HP-15C is a high-end scientific pocket calculator with a root-solver and numerical integration. The HP-15C is a high-end scientific programmable calculator of Hewlett-Packard's Voyager series produced between 19. They are listed on the “About” page, which is accessed by using the menu icon.USD 135 (Original) USD 99.99 - USD 179.99 (15C LE) The app responds to touch, mouse, and keyboard inputs. The tape can be copied and cleared the tape font size can be adjusted. If the display is too narrow, the tape is not visible, but can be seen in a popup window selected with the menu icon. The calculator has a “tape” that records each calculation. The number of decimal places and/or significant figures displayed is set by the user in a popup window accessed via the menu icon on the upper left. It supports fixed, scientific, general, engineering, and currency formats. RPN Scientific has a 25-level stack and supports ten store and recall memory locations. Results text can be copied to the clipboard. Users are assumed to be familiar with using RPN calculators. It performs most of the 10C’s math functions but does not include the ability to be programmed. It is free, does not contain any ads, and does not collect any information about you or your device. RPN Scientific is a scientific Reverse Polish Notation (RPN) calculator based on the venerable Hewlett Packard 10C scientific calculator. It is free, has no ads, and does not collect any information about you or your device. ![]() RPN Scientific is a scientific Reverse Polish Notation (RPN) calculator. ![]()
