NEW VERSION!

Option: True leather case!!

The HP-12C is HP's longest and best-selling product, in continual production since its introduction in 1981.^[1] Due to its simple operation for key financial calculations, the calculator long ago became the de facto standard among financial professionals – for example, most investment banks issue HP-12Cs to the members of each incoming class of its investment banking analysts and associates. Its popularity has endured despite the fact that even a simple, but iterative, process such as amortizing the interest over the life of a loan—a calculation which 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 Prof William Kahan (from UC Berkeley) and Roy Martin that is still in use today.

Later HP financial calculators are many times as fast with more functions, but none has been as successful. The HP-12C's programming mode is very intuitive and works like a macro operation on a computer. 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.) applicable to the solution. After the programming is complete, the macro will run in computation mode to save the user steps and improve accuracy. There are 99 lines of programmable memory on the HP-12C, and 400 lines on the HP-12C Platinum.

Over its lifespan, the processor's technology has been redesigned to integrate all the circuitry into a single chip 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 the users did not trust results obtained too quickly and so the CPU speed was never improved from the original 200 or so kHz.^{[citation needed]} In the late 1990s, the CPU was changed to a 3V process and the battery was changed to a single 3V cell.

In 2008, HP modified the design so that new production runs contain an ARM processor which runs an emulated version of previous chips. This has brought advanced possibilities such as flashing new firmware, not previously possible. HP also released a software development kit (SDK), making it possible to make new and custom operating systems. The calculator runs 20 times faster on most benchmark operations. This version is colloquially known as the HP-12C+ although HP does not market it as a different product. This is the version sold by TheCalculatorStore.com.

The HP-12C is one of only four calculators permissible in the Chartered Financial Analyst exams, the others being its sister, the HP-12C Platinum, and the Texas Instruments BA II Plus and BA II Plus Professional.

Made in the Philippines.

Leather case: Standard = normal PE case (NOT learther)

NEW VERSION - MULTILINGUAL!

More powerful and capable than ever, the HP 12c Platinum is up to 6 times faster with 4 times more memory than the original HP 12c. (the current HP 12c in this shop is a new model based in the ARM processor which is 25 times faster than the HP 12c Platinum) However, it takes up to 399 program lines, compared with just 99 of the plain 12c model.

Choose between RPN1 or algebraic entry-system logic, handle up to 80 cash flows and utilize over 130 built-in functions.

Now with the option of true leather case! (in addition to the original case)

As many of our customers are calculator collectors, we have created "collectors' packs".

This is the Financial Calculators Pack, which includes the 4 current financial calculators: HP10bII+, HP12c, HP12c Platinum, and HP17bII+

The bundle has a 20% discount over the list price.

Leather cover set:

- Brown for HP17bII (all types)

- Black, brown and Bordeaux for Voyager calculators

New, true leather case for HP Voyager calculators, including HP12c, HP12c Platinum, HP10c, HP11c, HP15c, HP16c calculators.

Note: this is not an original HP product.

The original Voyager calculators had a vinyl case that resisted quite well the passage of time - and that was designed to be kept in the jacket pocket. It also had the knitting "inwards so that it occupied the less possible space for a given volume.

Later versions (including anniversary units) have been made in false leather (called PE), which has a very low resistence to external scratches. There are several types but all of them in my possession have now a very bad aspect. For the current HP12c Platinum, the case is not even suited for jacket pocket, since it has very square corners

We have decided to create real leather cases that stand the passage of time, made with the same material that pocked cardholders and money holders are made. We have selected a manufacturer in Ubrique (Spain), famous for this kind of work. We sent to them the originals and the calculators that go with it, so that the case you have with you is not something similar that fits well - it has been expressly designed for your calculator

Please take a look also to the leather cases for Pioneer (HP17bII and HP42s types) and HP41c cases.

Original HP17bII calculator. Excellent state. Includes original cover and English manual. Works with both Algebraic and RPN

Other features included:

• Basic four math functions plus logarithms, reciprocal, factorial etc. (Some hidden under the MATH menu.)
• Algebraic solver.
• Basic business/financial functions including Time Value of Money, cash flows, bonds, depreciation business percentages etc.
• Basic statistics.
• Time and appointments.
• A beeper which beeped on appointments and optionally on errors.
• Infrared printing.
• 6.7K Bytes of user memory.

Please see the review in our blog!

The HP-18C was HP's first RPL-based calculator even though this model was not user programmable. The user did have a solver (another HP first) available, but only had about 1.5 K of continuous memory available to store equations. The calculator had many functions buried in a menu structure. It is very similar to the HP19BII, but missing RPN logic.

This unit has a wonderful true leather carrying bag (pictured)

This calculator was the intermediate step between the current HP 17bII and the old, Pioneer-style HP 17bII. Main differences with the original are increased memory (up to 28 kb), and the currency exchange menu. There is as well the "key feel": while both have good tactile feedback and never miss a key, some called "hollow" the keyboard touch of the 17bII+

The calculator is in perfect shape, with some dust specs in the screen (already there when I bought it). However, the pouch is a little bit "battered" - see enclosed pictures.
