HP12 Platinum Processor Speed Message #1 Posted by Andy on 15 Mar 2004, 4:16 p.m. Heard rumors that the machine has a faster processor but the speed was intentionally crippled. Can anyone confirm? It sounds too unbelievably stupid, even for HP.

Re: HP12 Platinum Processor Speed Message #2 Posted by Jeff on 16 Mar 2004, 8:43 a.m., in response to message #1 by Andy Who knows why that is. I heard that it's slower because it uses algabraec (sp?) and RPN, and that causes inefficiency. I don't know, though. I know that I did buy a Platinum and I didn't like the feel of it, the lighter and harder to read number display, and the slowness. I took it back and got a old-fashioned 12C and am glad I did.

Re: HP12 Platinum Processor Speed Message #3 Posted by Veli-Pekka Nousiainen on 16 Mar 2004, 4:47 p.m., in response to message #2 by Jeff I bought the new hp 12C Turbo and it is lightning fast. Even If I have very irregular cashflows (more than a thousand) it calculatest both the IRR and the NPV in a blink of an eye Even the most demanding program loops (solving the integration limits of a triple integrals using thousand digits accuracy) takes less than a second The only problem is that I have to change the batteries every five minutes as they die very quickly....

And before you can change them, you have to wait for them to cool down!

Re: HP12 Platinum Processor Speed Message #6 Posted by Wayne Stephens on 17 Mar 2004, 7:30 a.m., in response to message #3 by Veli-Pekka Nousiainen I hooked mine up to a car battery with the voltage stepped down. After a while the "12C Turbo" was calculating faster than I could hit the keys (which were getting very warm). I ended up leaving it alone in a room and it did my taxes, amortized my mortgage, got my bond rating increased to "A", offered short and long-term investment advice (seemingly very sound investment advice by the way), and then blew up. I guess I'll have to get another one. On the other hand, I do have a regular 12C, and that Garrett turbo-charger is just sitting on the shelf in my garage... Hmmmm. Take care. Wayne

Re: HP12 Platinum Processor Speed Message #8 Posted by Julián Miranda on 18 Mar 2004, 2:06 p.m., in response to message #7 by bill platt I think the Endurance World Championship is more suitable for the 12C, from 1981 till ...
