My HP 10bII+ is much faster than HP 12c!
Hi guys!
As an Econ student I decided to first buy the HP10BII+ for its price and functionalities. My cousin gifted me his Hp12c Platinum, 1 battery on the back and CN serial number engraved on the case, not as a sticker, that I had to sent to repair for just 20 bucks and needless to say I was stoked. The problem now is that my 10bII+ feels so much faster and it never has the "running" sign. For instance, the 12c took whooping 25 seconds when trying to calculate the required interest rate for a 45 PMT, 10925.76 FV and an N of 168 while the 10bII+ did it INSTANTLY! I'd like to know if it's something with my calculator and if I should stick with the 10bII+. Thanks a lot guys!

While the 10bII+ lacks RPN and the classic style and hardware quality feel of the 12C, it is a superior machine in just about every way, including dramatic speed increase as you've found. I believe it also uses higher precision math (Tim?) internally, plus provides extended math functions not available on the 12C/12CP. It's a great choice if you're happy with Algebraic logic, there's nothing like it in its price range. Search old Forum posts here, there are lots of comments, virtually all are positive. Enjoy your 10bII+. Bob Prosperi

So will do the most recent HP12C, a. k. a. HP12C+: http://www.hpmuseum.org/cgisys/cgiwrap/...ead=177549

Yeah, that is pretty much normal. There are only 2 or 3 calculations that can possibly show the "running" message if I remember correctly due to the speed. (inverse T, cflow, interest calc  if memory serves right) As others have pointed out, provided you can live with the nonRPN, the nonprogramability, and the "not quite as good hardware"  it actually is a more capable unit. The 12cp will be much slower then either a new 12c or the 10bII+ (which both use a modern, ARM processor while the 12cp uses a very slow, older design). When comparing the original 12C compared with the newer 12cp, you'd generally see anywhere from a 4x8x speed increase over the original 12C. The newer 12C is about 120x140x the speed of the original. The 10bII+ will be in the same speed range. There are some exams that only allow either the 12C/12CP from the HP side of things (CFA/CFP???). So that might be important to check for you depending on future plans. There is a rather authoritative 10bII+ review found in a newsletter here if you are interested. http://h20331.www2.hp.com/hpsub/download...011_v2.pdf Quote:I believe it also uses higher precision math (Tim?) internally, plus provides extended math functions not available on the 12C/12CP. Yes, the 12/15 digit napier library is in use on the 10bII+. TW Although I work for the HP calculator group, the views and opinions I post here are my own.

Wow! I am "authoritative" ?

What a bummer! I thought I had a good unit in my hands! The repair guy even hyped me up by showing the inside made of metal compared to a flimsy Chinese model. He told me they don't manufacture it like that anymore and that I had been lucky!
I have to confess I really want to stick with the 12c, which is much better looking and has a hard leather case. I'm not planning on becoming a CFA, though. I guess I can live with the "running" message if it only happens in a few calculations. I just wish there was a way to upgrade its processor, haha.

Hello,
The microprocessor is already upgraded (runs a 48Mhz)... The 12C is slower than the 10BII+, which uses the same CPU, solely because the 12C is emulating the old CPU and that the old algorithms were not as good as the new ones... Cyrille Although I work for the HP calculator group, the views and opinions I post here are my own. I do not speak for HP.
