However, HP's market research found in the late 1980s that users did not trust results obtained too quickly and so the CPU speed was never improved from the original 884 kHz, but the speed could be increased by a user modification.

HP-12C Type Manufacturer Introduced 1981 Cost ca. Due to its simple operation for key financial calculations, the calculator long ago became the standard among financial professionals. Its popularity has endured despite the fact that even a relatively simple, but iterative, process such as amortizing the over the life of a loan — a calculation which modern can complete almost instantly — can take over a minute with the HP-12C. The 1977 October edition of the 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 from and Roy Martin that is still in use today. Later HP financial calculators are many times faster with more functions, but none have been as successful. Basically, the keys one would press in the calculating mode to arrive at a solution are entered in the programming mode along with logical operators if, and, etc. After the programming is complete, the macro will run in the computation mode to save the user steps and improve accuracy. There are 99 lines of programmable memory on the HP-12C. Models HP-12C There were at least eight hardware revisions of the HP-12C since 1981 including one special issue. Over its lifespan, the proprietary HP Nut originally the 1LF5, then 1LM2 processor's technology has been redesigned to integrate all the circuitry into a single chip first the 1LQ9, then 1RR2 and to refresh the manufacturing process as the foundry could no longer manufacture the necessary chips, having moved on to making higher-density chips. However, HP's market research found in the late 1980s that users did not trust results obtained too quickly and so the CPU speed was never improved from the original 884 kHz, but the speed could be increased by a user modification. In the late 1990s, the CPU was changed to a 3 V process 2AF1-0001, later a 2AF1-0002 and the battery was therefore changed to a single cell replacing the three cells previously used F1637A. In 2008, HP modified the design to use an processor with core running a software emulator of the previous Nut processor, written by Cyrille de Brébisson, in order to execute an image of the former Nut-based firmware in it. This has brought advanced possibilities such as flashing new firmware, not previously possible. HP also released a SDK , making it possible to make new and custom. The calculator ran 60-90 times faster on most benchmark operations. In contrast to the preceding revision, it supported two parallel cells, of which only one was necessary to run the calculator. Based on the same processor, a limited HP 12c 30th Anniversary Edition NW258AA was introduced in 2011. Only 40,000 of this model were made. The internal hardware of the HP-12C changed again in 2015, when the design switched to use an Atmel processor with core. It continues to use two parallel CR2032 cells. The firmware reports a 2015 build date. The 2×3-pin flash port now uses the protocol instead of a TTL serial protocol; in addition to this, the calculator's circuit board features an unpopulated mount for a connector. The HP-12C is one of only four calculators permissible in the exams, the others being its sister, the , and the. Proponents, however, are quick to note that the HP-12C continues to be both the and standard of high finance. It allows input to be entered in as well as in. 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. The first HP 12c Platinum version F2231A did not have parentheses, which often led to awkward key sequences to solve problems in algebraic mode. Since 2005, newer versions F2232A of the HP 12c Platinum have parentheses on the blue-shifted functions of the STO and RCL keys. They also support undo and backspace and provide memory for up to 80 CFj registers. The firmware changes increased the ROM size beyond the capabilities of the original processor, so it was replaced by the Generalplus still with core , which is also faster. It was manufactured by. Also based on the GPLB31A, the HP 12c Prestige F2233A features a gold-colored plate like the original 12C, but is otherwise like the second HP 12c Platinum model. The latest revision of the 12c Platinum was introduced in 2010 apparently still with product code F2232A. Like in the later revisions of the 12C, it features two parallel rather than only one cells, but it continues to be based on the GPLB31A processor. Bugs and problems The Aurora FN1000 calculator in clamshell design was closely inspired by the HP-12C in 2003. Capitalizing on the limited availability of the HP 12c Platinum 25th Anniversary Edition, released the Victor V12 in 2007 which was a budget priced clone of the HP 12c Platinum edition. It is also available as BrtC FC-12 in Brazil. The 2010 Compucessory CCS28956 aka Compucessory 28956, a clamshell design, is another clone of the HP 12c Platinum, but with added margin calculation functions COST, SELL, MGN. The Truly SC123 in 2015 closely resembles the HP 12c Platinum as well, but in a vertical case layout. In 2012, aka RPN-Calc introduced a miniature clone named DM-12CC approximating the size of a credit card 88 mm × 59 mm × 7 mm. It closely emulates the functionality of the original HP-12C by running the original ROM image in an emulator on an -based 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. In February 2016, SwissMicros introduced the DM12L, a version of the calculator about the same size as the original HP-12C. Deviating from the HP original, these calculators feature a dot-matrix display, switchable fonts and clock speeds, and, based on a CP2102 converter chip, they come with a serial interface to exchange data with a PC etc. San Diego, CA, USA:.
