Texas Instruments RPN calculator - Graeme W. - 08-13-2003 Surely the HP32SII production line is not that cold that it couldn't be restarted in Indonesia so that HP could get back to producing at least one single classic calculator - surely that's not too much to ask is it!!!! - just one single solitary measly lonesome classic calculator - why the hell is that so difficult to do. HP just had a calculator competition to determine what the kids would like to see in a calculator.....ummmmmmmm.......why don't they ask the veteran/expert users instead (sorry kids). Some of these veteran users have been using HP and RPN since 1972 and might possibly know a couple of things (more likely a thousand good ideas some of which have already been mentioned on this site). It's now totally apparent that the HP calculator design contract was won by a Canon or Casio design bureau. Take all the tell-tale labels off the HP33S and ask the public what brand of calculator it is - guaranteed 99 percent would say its a Canon or maybe a Casio ... no.... it must be the new Sharp model. Maybe someone should be tapping Texas Instruments on the shoulder to try to get them into RPN machines - after all HP cross-dressed into algebraic machines. Maybe TI would do a better design job and produce a classic looking machine ... desperate times require desperate measures.
Re: Texas Instruments RPN calculator - Ron Ross - 08-13-2003 I think it would be a wasted effort. As long as Hp is even remotely capable of making or outsourcing a calculator, Ti will never make an RPN model (the Ti-89 has a pretty good download to change it over to an RPN, I am told, but that was developed outside of Ti). Why? Because that just might breathe new life into a competitor on the ropes (HP). There is a whole decade of Ti users and a new Hp calculator user is in the EXTREME minority (and I would bet 2/3's of the new users are using Algebraics, since that is what many new Hp's are). Textbooks are written around Ti calculators. Why would Ti even think to make an RPN to admit or recognize its merit? But that is only my belief, and you could certainly campaign Ti to do otherwise.
And concerning many of the new Hp algebraic models, while they may be superior to their competetion, they are not significantly superior to warrent any tears if they disappear. I'll use an Hp39G as an example. It has lots more functions and capability and 10 times the RAM as Ti's 83 series. Very similiar and you could almost use their manuals interchangably. But they are not identical, and when the text book is using a Ti-83 for examples, what calculator do you think the student or parent will buy? The point is: - Harry (Germany) - 08-13-2003 All those "veteran/expert" users already HAVE RPN calculators that they use. Regars, Harry, who is very disapointed that nowadays it is not quality, but design that is important.
btw, its the same with cars: Re: The point is: (LONG) - bill platt - 08-13-2003 Harry,
On the other hand, if you read any industry magazines from the world of photonics, electronics, microelectronics, or robotics, you will see great enthusiasm for the ability to do anything formerly requiring mechanical action by using electronics. I have read just such a piece regarding automobile stability and control!
What does this have to do with calculators? The same dynamics are at work---the products are produced using 3-D wiz-bang total product models, TQM ("total quality management") and "advanced analysis" (read: the software thinks instead of the engineer) and so in the nd, you have no real quality--only what a robot "thought" would work. I suspect this is why the 12C has the problems it does.

hp's marketing strategery (rant) - ned - 08-13-2003 HP contracted Kinpo to build their calcs. This company makes perfectly good ones branded as Citizen. The 30s is an example of straight rebranding of an OEM, in this case the Citizen SR260. The 9s is the SRP325g, which is a redone Casio fx-6300. The 33s, 48ii, and 49+ all appear to be designed exclusively for HP, as evidenced by the keys EVAL, R/S etc. Re: The point is: (LONG) - Harry (Germany) - 08-13-2003 I got my first Calculator - a HP 32S - in 1989. Although I wasn't allowed to use it in class at that time. I don't know about now, but back then we started using calculators in class from 8th grade on. That was in 1992 for me. Looking for pictures of that ugly Pontiac now ;)

I totaly agree with you. I am studying electronics engineering, and this happens to me all the time.
Regards, TI 89 RPN program is great! - Matt Kernal - 08-13-2003 Ron > (the Ti-89 has a pretty good download to change it over to an RPN, I am told, but that was developed outside of Ti) I picked up a TI 89 for $40 a couple years ago just to try out Lars Frederiksen's RPN program. What a nice (and fast) interface! One really cool aspect is that as you perform a calculation (in rpn entry format.. working from the inside out.. ie. no parenthesis), it builds/maintains a "history", in algebraic format, as the calculation is entered. In other words, the history shows the same calculation, as if you entered it algebraically (ie. it shows the calculation in the order it was calculated with parentheses inserted). It is by far, the BEST way I have seen to teach an "RPN impaired" person how/why RPN is so efficient, while also reinforcing rules of precedence (order-of-operations). I must admit, I only use it (TI 89) as a four-banger calculator (can't stand SO MANY things about the TI 89). Matt
ps. I should take a stab at writing a similar app for the 48/49G series.
Re: The point is: (LONG) - Eduardo - 08-13-2003 The word in English is "one-to-one". Your question can be rephrased as: "why is the Laplace transform one-to-one?" (sometimes the term "injective" is used instead).

Fundamentals... - Karl Schneider - 08-14-2003 "bill platt" wrote:
Quote: Right on, Bill! I've noticed a general de-emphasis of fundamentals, too. There could be several reasons: 1. Students are expected to cover more topics and advanced material in their "4-year" degree programs, so they don't spend as much time learning the fundamentals. 2. Computing devices (more PC's than calculators) make it so easy to get answers without analyzing the problem from a fundamental standpoint. 3. Higher emphasis on short-term payback can result in "solutions" intended to make distinct impressions rather than to withstand the test of time. 4. Rapidly-advancing and more-complex technologies make it more difficult for most people to comprehend the fundamentals, except for the exclusive "cognosenti" (sp?)
Quote: I assume that this was in high school. I bought my first HP (15C) as a college junior in 1983, after being enthralled by the 41C in 1980-81. I think it was more a matter of "kids" not being able to comfortably afford HP's until the mid-80's. The $115 I paid exceeded my monthly scholarship stipend.
Thank you Eduardo!! - Harry (Germany) - 08-14-2003 no text
