HP 12C Platinum - a mystery Message #1 Posted by Luc Chanh Truong Vietnam on 16 June 2003, 10:56 p.m. Hello, my friends. Yesterday, I read some pages in the HP 12 C Platinum owner's hanbook, i found a mystery: - in page 61, HP wrote : "Calculating NPV for Grouped Cash Flows. A maximum of 30 cash flow amounts (in addition to the initial investment CF0) can be stored in the HP 12C Platinum.15; - and also in page 61, at footnote paragraph for note 15, HP wrote:"15.If you have stored a program in the calculator, the number of registers available for storing cash flow amounts may be less than 31" So, HP said that HP 12 C Platinum has "Capability to handle up to 30 cash flows" (20 cashflows in HP 12C), in fact HP 12 C Plat has to share memories (when store 30 cashflow) with memories of programming (if they are idle). Besides, HP said that 12C Platinum has more than 130 built-in functions (120+ in classical 12C, I think that 10 new build in functions reserved for algebraic entry keystrote. In short, what's news in HP 12C Platinum: - algebraic entry; - Keystroke programming performs up to 400 steps (you need ?); - Sofware source was be rewritten (more reliable than classical 12 C ?). That all. Any comment else.

HP 12CP ? That's all? no there's more, Message #2 Posted by Norm on 16 June 2003, 11:29 p.m., in response to message #1 by Luc Chanh Truong Vietnam LCTV wrote: In short, what's news in HP 12C Platinum: - algebraic entry; - Keystroke programming performs up to 400 steps (you need ?); - Sofware source was be rewritten (more reliable than classical 12 C ?). That all. ************************ Hey wait a minute here !!!! You forgot what else they did !! They came up with a color scheme featuring ugly aluminum front panel they call "platinum", virtually unreadable light yellow lettering on the aluminum, and they changed the color of the plastic to a dark blue. So don't forget that they put a lot of engineering department resources into that color scheme. Of course, a monkey throwing darts at a color wheel would've done better ..... we can laugh at the HP execs on this one.... it's THEIR BUSINESS CALCULATOR, THEY have to use it ! har har har . Youd think it was for the engineers when they screw up the colors like that.

Re: HP 12C Platinum - (another) mystery Message #4 Posted by Luk on 16 June 2003, 11:55 p.m., in response to message #1 by Luc Chanh Truong Vietnam Page 62: (3) If the initial investment consists of more than one cash flow... key in the number of those cash flows, then press [g][Nj]. DOES NOT WORK! It works on the original HP-12C though.

Re: HP 12C Platinum - (another) mystery Message #6 Posted by Ellis Easley on 18 June 2003, 1:38 p.m., in response to message #4 by Luk I've poked around with my financial calculators just to learn how they work, and I find that that some, like the 12C, let you treat the first cash flow as a member of a cash flow group (n[0]>=1) and some, like the 10B, call it an "initial investment" (n[0]=1). I think in either case, the actual first cash flow (either the first cash flow of the first group or the initial investment) is treated differently - it inherently happens at the beginning of the first period. But this sounds like another exception to the proposition that the 12C Platinum contains most of the 12C ROM and a Nut emulator. It sounds like they picked something out of the 10B manual.
