hard coded delay
"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." I put it back because it's a good story (but of course wikipedia isn't here to propagate urban legends), and the template:fact tag is here to take it with a grain of salt, and asks for verification. --Marc Lacoste 09:40, 31 May 2006 (UTC)


 * That's fine; I remember reading it somewhere, but haven't been able to find it again. Maybe someone else will have better luck. Tom Harrison Talk 13:43, 31 May 2006 (UTC)

"redesigned from scratch"
The 12cp is very similar to the 12c, and not just in it's layout. I have always seen the platinum version reffered to as a reimplementation, rather than a redesign. Does anybody have a source for the extent of the design changes made to produce the platinum?

Hello, when the article states "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 spreadsheets can complete almost instantly--can take over a minute with the HP-12C." It should be pointed out that the HP-12c Platinum is really quite a lot faster then the original HP-12c and certainly no longer takes a minute to compute things with a lot of iterations such as amortizing interest or calculating IRR.

Lot o' Crap
"People have been known to take an HP-12C into a mortgage-broker's office and tell the broker the monthly payments on a proposed loan, well before the banker could compute the number, because most bankers had to look up a number in a thick book of mortgage tables, while this calculator could compute it directly."

This is pure Urban Legend.

Also, the HP-12C is NOT known as the Papal calculator. Just making it up as you go along are we? 209.29.88.44 (talk) 13:16, 17 November 2007 (UTC)

Well, I confess to using mine in the car dealership with the leasing officer. —Preceding unsigned comment added by 207.203.19.203 (talk) 20:20, 14 December 2007 (UTC)

I've done this on several occasions using several different calculators (just depended on which I had with me); my wife has done this too, with her very old 12c. Either of us is usually faster than the bank person, even if they're using their own 12c. htom (talk) 21:22, 6 April 2012 (UTC)

HP-12C
I think, the HP-12C should have an own article and be outsourced from this article. Please compare with de:HP-12C and pt:HP 12C. So long --JWBE (talk) 19:37, 12 July 2010 (UTC)

Reported features of the HP-11C?
I hope I am in the right place for this... Anyway I came here to find some facts abouyt the HP-11C calc and notice some possible errors in the table that appears in the article. My only wish is to set straight the reported available conditional expressions that are reported as being unavailable on the 11C. the table lists 4 conditions as being not available in two red boxes marked with "no". Provided I am understanding things correctly, when I look at my HP 11C I am able to see that the four expressions are present and able to be used. THe four expressions are: x<0,x>y,x>0,x (not equal to)0. If I am mistaken please excuse me. Endorfun86 (talk) 07:07, 14 April 2011 (UTC)
