For those of us who grew up using the 12C in business school, and later in business, this is a perfect app. The frustrating part so is that it does not look exactly like the one we've all used. The color is different, the font of the numbers is different, etc. Which HP12C calculator function did you find particularly useful? Do you have further tips to share?

Introduction

Although Reverse Polish Notation (RPN) – the HP12C’s mathematical notation – may initially take some getting used to, it offers some advantages over non-RPN devices. A final interesting detail is that the horizontal layout and metallic edging came about because the display was found to break when prototype vertical Voyagers were dropped - so the display was placed horizontally - leading to a horizontal layout for the HP-12C - and giving HP their most successful stopgap product ever. The metallic bezel is now platinum in colour rather than gold and there is four times the amount of memory for programs. There are a couple of new software features added, most notably the ability to use arithmetic mode rather than RPN and the somewhat more minor addition of x 2. For the really paranoid, we suggest that you bring two calculators instead (that’s right — quite a few candidates do that 😉 ) Get these CFA Calculator Discounts before It’s Too Late!

The HP calculators Voyager series consisted of five models, some of which were manufactured in several variants (with years of production):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 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. It may make sense to buy a used calculator to save a few dollars, but in this instance, the calculator may not function properly, and you won’t have a warranty to get it fixed. Even if it works fine, you can’t be certain that the battery will be operational, and this could end up costing you even more. a b Hidalgo, Jordi (2004-06-09).

When deciding between the Texas Instruments BA II Plus vs. Professional model, the professional version has a more solid case. The keypad is less flimsy, but there are still some complaints of the keys being too hard to press or too slow to register.

History

Note: Hitting [f] REGwill clear the storage registers. You may also overwrite a single stored register by storing a new value in the register. R0… R9/ CF0… CF9, R.0… R.9/ CF10… CF19) + 5 ( n, i, PV, PMT, FV/ CF20) + 5 ( X, Y, Z, T, LAST X) [3] By default, the HP12C will show only two decimals places. To modify the number of places displayed, hit the yellow [f]prefix key followed by the number of places you wish to display. For example, to display five decimal places, you would key:

A simple example: if you used the HP12C to add 6 and 7, you would input “ 6 7 +” rather than the ‘usual’ “6 + 7”. 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.

Questions from Readers about CFA Calculators

The five keys in the top left corner (including their [f]and [g]functions) are all used for these types of problems. 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.
