From Wiki
Hewlett Packard HP-12C
- Type: Programmable RPN Electronic Calculator
- Size: 3 x 5 inches / 8 x 13 cm
- Serial number: CN34902310
- Date of Manufacture: December 2003
The HP-12C financial calculator was introduced in 1981, and is the only one of the popular Voyager series of calculators to stand the test of time. Currently there are three major variations of this calculator, including the HP-12C Platinum and the HP-12C Platinum 25th Anniversary Edition. The 12C is the only purely RPN calculator still sold by HP; the other calculators that support RPN also support semialgebraic entry as an optional setting.
Financial stuff baffles me. How can someone take the wonderful set of mathematical knowledge we humans derived over the last 4000 years and make these weird compound interest and sinking fund thingies is beyond me. I'm sure no good will come of it. Money is the root of all evil, after all. Anyway, for the times I get confused, there is a nice little cheat-sheet on the reverse side.
Low-power design permits the calculator to go 6-12 months between changes of standard, store-bought, button batteries. No more worrying about replacing that darned custom battery pack!
