The available programming features differentiate between the various HP Voyager series calculator systems. The HP12c Platinum is similar in appearance and functionality to the 12C, and is designed to mimic the 12C whilst extending its capabilities in various aspects. The calculator was introduced in 2003, is visibly distinguished by its silver-colored upper half as opposed to the gold-colored plate on the original 12c. There are six variants of the HP12c Platinum (including two special issues). Based on the same processor, a limited HP12c 30th Anniversary Edition (NW258AA) was introduced in 2011. [14] Only 40,000 of this model were made. later 12c Platinum variants: 7…20 ( R0… R9/ CF0… CF9, R.0… R.9/ CF10… CF19) + 5 ( n, i, PV, PMT, FV) + 61 ( CF20, CF21… CF80) + 5 ( X, Y, Z, T, LAST X)

The HP-12C is HP's longest and best-selling product, in continual production since its introduction in 1981. Due to its simple operation for key financial calculations, the calculator long ago became the de facto standard among financial professionals. [4] Its popularity has endured despite a relatively simple but iterative process such as amortizing the interest over the life of a loan, a calculation that modern spreadsheets can complete almost instantly, can take over a minute with the HP-12C. The 1977 October edition of the HP Journal contains an article by Roy Martin, the inventor of the simple method of operation used in HP financial calculators, which describes, in detail, the mathematics and functionality built by William Kahan and Roy Martin that is still used today. [5] Models [ edit ] HP-12C [ edit ] The Aurora FN1000 calculator in clamshell design was closely inspired by the HP-12C in 2003. Capitalizing on the limited availability of the HP12c Platinum 25th Anniversary Edition, Victor Technology released the Victor V12 in 2007 which was a budget priced clone of the HP12c Platinum edition. It is also available as BrtC FC-12 in Brazil. The 2010 Compucessory CCS28956 [24] aka Compucessory 28956, [25] a clamshell design, is another clone of the HP12c Platinum, but with added margin calculation functions (COST, SELL, MGN). It is also available as Procalc FN 1200C in Brazil. The Truly SC123 in 2015 closely resembles the HP12c Platinum as well, but in a vertical case layout. a b Without DSZ/DSE (Decrement and Skip) and ISZ/ISG (Increment and Skip) writing loops is difficult. The internal hardware of the HP-12C changed again in 2015, when the design switched to use an Atmel ATSAM4LC2CA-AU processor with ARM Cortex-M4 core. [2] The calculator's part number and physical appearance didn't change except for a "Rev 2" plate on the bottom side. [2] It continues to use two parallel CR2032 cells. [2] The firmware reports a 2015 build date. [2] Serial numbers starting with "PHA", "9CJ", "7CD", or "3CD" rule out the older model variant. [2] The 2×3-pin flash port now uses the USB protocol instead of a TTL serial protocol; [2] in addition to this, the calculator's circuit board features an unpopulated mount for a Micro-USB connector. [2] In 2012, SwissMicros (aka RPN-Calc) introduced a miniature clone named DM-12CC approximating the size of an ID-1 credit card (88mm× 59mm× 7mm). It closely emulates the functionality of the original HP-12C by running the original ROM image in an emulator on an ARM Cortex-M0-based NXP LPC1114 processor. Newer DM12 models since 2013 feature a better keyboard and more RAM ( LPC1115). A DM12 Silver Edition in a titanium case is available as well. [26]

Nut core (HP 1LF5 / HP 1LM2 / HP 1LQ9 / HP 1RR2 / Agilent/ Marvell 2AF1 [1]) / ARM7TDMI core ( Atmel AT91SAM7L128 [1]) / ARM Cortex-M4 core ( Atmel ATSAM4LC2CA [2]) The HP Voyager series calculator are keystroke programmable, meaning that it can remember and later execute sequences of keystrokes to solve particular problems of interest to the user. These keystroke programs, in addition to performing any operation normally available on the keyboard, can also make use of conditional and unconditional branching and looping instructions, allowing programs to perform repetitive operations and make decisions. For example, Goldman Sachs issues HP-12Cs to the members of each new incoming class of its analysts and associates. a b Furr, Richard (2003-01-22). "HP Calculators by Date of Introduction".

In February 2016, SwissMicros introduced the DM12L, a version of the calculator about the same size as the original HP-12C. The first release of the 12c Platinum used a faster processor than the revision of the original HP-12C which was available at that time. (However, the subsequent revisions of the original 12C which switched to ARM-based processors have reversed that speed gap.) It was equipped with a Sunplus SPLB20D2 [1] [18] with a 6502 core, larger memory (for up to 30 CFj registers [17] and 400 program steps) and more built-in functions. It allows input to be entered in algebraic mode as well as in 4-level classical RPN. The calculator's particular implementation of RPN exhibits an unusual behaviour of the CHS key different from that of the 12C and other classical RPN calculators. [19]The HP calculators Voyager series consisted of five models, some of which were manufactured in several variants (with years of production): The HP-16C is a computer programmer's calculator, designed to assist in debugging. It can display numbers in hexadecimal, decimal, octal and binary, and convert numbers from one base to another. A number of specialized functions are provided to assist the programmer, including left- and right-shifting, masking, and bitwise logical operations. HP has (as of 2015) never made another programmer's calculator, but has incorporated the 16C's functions in later calculator models. a b Kuperus, Klaas (2022-09-10). "HHC 2022: HP Calculators Distribution (Klaas Kuperus)". HP Handheld Conference 2022. Nashville, Tennessee, USA . Retrieved 2023-08-11. The HP-10C is the last and lowest-featured calculator in this line, even though its number would suggest an earlier origin. The 10C was a basic scientific programmable calculator. While a useful general purpose RPN calculator, the HP-11C offered twice as much for only a slight increase in price. Designed to be an introductory calculator, it was still costly compared to the competition, and many looking at an HP would just step up to the better HP-11C. Poor sales led to a very short market life, making it one of the most difficult of the series to find today. In 2011, the continued popularity of the Voyager series among users prompted SwissMicros (originally called RPN-Calc) to produce a series of credit-card-sized calculators looking like miniature versions of their HP equivalents and running the original HP firmware in an emulator on a modern calculator hardware. The series consisted of the DM10, DM11, DM12, DM15 and DM16. [9] All calculators used the same hardware, but differ in keyboard and firmware (which can be changed with an upgrade port). After the introduction of the larger DM15L, DM41L and DM16L in 2015, the DM11L was added in January 2016 with the DM12L following in February. A limited production run for a DM10L was planned for 2019. [10] [11] See also [ edit ]
