The 10C series consisted of five models:
THE HP-10C 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. 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 relatively expensive 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. THE HP-12C The HP-12C is a popular Financial calculator. It was such a successful model that Hewlett-Packard redesigned it from scratch, adding several new functions, and introduced the '''HP-12C Platinum''' in 2003 . 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. Its popularity has endured despite the fact that even a relatively simple, but iterative, process such as amortizing the Interest over the life of a loan--a calculation which modern Spreadsheet s can complete almost instantly--can take over a minute with the HP-12C. Later HP financial calculators are many times as fast with more functions, but none has been as successful. The HP-12C's programing mode is very intuitive and works like a macro operation on a computer. Basically, the keys you would press in the calculating mode to arrive at a solution are entered in the programing mode along with logical operaters (if, and, etc.) applicable to the solution. After the programing is complete the macro will run in the computation mode to save the user steps and improve accuracy. There are 99 lines of programable memory on the HP-12C. Over its lifespan, the battery-compartment design has changed and faster processors have been used. However, HP's market research found the users did not trust results obtained so quickly and so its engineers have introduced some delay in the code. The HP-12C is one of only two calculators permissible in the Chartered Financial Analyst exams, the other being the Texas Instruments BAII. THE HP-11C AND HP-15C The HP-11C is a mid-range scientific programmable. The '''HP-15C''' is a high-end scientific programmable with a root-solver and numerical integration. It is able to handle complex numbers and matrix operations. THE HP-16C 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 from one to the other. To accomodate long binary numbers, the display could be 'windowed' by shifting it left and right. For consistency with the computer the programmer was working with, the word size could be set to different values from 1 to 64 bits. Binary arithmetic operations could be performed as unsigned, 1's or 2's complement. This allowed the calculator to emmulate the programmer's computer. A number of specialized functions were provided to assist the programmer, including left and right shifting, masking, and bitwise logical operations. Sales were poor, and no similar calculators have been made. REFERENCES SEE ALSO NOTES |
