It'd look unusual at first but we could reap the practical benefits of having the operators and ENTER next to each other and at the same time wouldn't alienate potential new users who expect operators on the right. If the 43S aims to attract a broader audience, we have to pick our fights: I think RPN is a genuinely useful invention worth promoting, but which side the ENTER key and the operators occupy is relatively unimportant. |

I stand with what I wrote, and yes, I already said that what I really want is only a working unit on sale. Given that I wouldn't care that much which side operators are on. After some thought I realized that I already have to adapt to different keyboard incarnations (plastifications?), be them physical or virtual. So I would gladly take operators AND ENTER on the right side. However I don't understand why those fabled new users should expect operators on the right side. I see lots of calculators with operators on the right, yes, but which right is right? or or or we all know this one and why not this? Why fabled new users? Because this won't be a cheap calculator, for the casual shopper. I fear there won't be so many of them beyond our community. Of course I hope to be proved wrong so the developers will be happy! ;) P.S. My tagline is still valid, though :) Greetings, Massimo -+×÷ ↔ left is right and right is wrong |

The 50g proved to me that a large Enter key isn't necessary and can become comfortable more quickly than I would have believed. And the Prime (with all on the right) has become comfortable too, though less so, probably because I use it far less. If I had to do math on a calculator with a blindfold and a gun to my head, I guess I would pick a Pioneer, despite having been raised on classic-thru-nut machines. It seems many years of muscle-memory wins over initial training. Fortunately, very few gun-wielding mathematicians care as much as we do about this, so I feel I can adapt, as I have many times before. Like most of you, I just want it to get here, so we can begin our precise, fact-based criticism phase. --Bob Prosperi |

When I first mentioned the 34S to my father, he showed his ancient algebraic TI from the 1970s and exclaimed he didn't see much point in contorting the way he performs calculations if even the old device could do better. Then he got a 34S for Christmas along with a concise explanation of how RPN works and why it makes sense. A few weeks later he said something like he didn't understand why everybody wasn't using RPN. I gave away nine 34S and 31S calculators (modified to be more user friendly) as Christmas presents and promised to deliver a tenth one. All to people who never used RPN before, and all (except my father) younger than what I estimate the average age could be here, four of them under 25. The calculators were well received and while I expect some will ultimately end up collecting dust, I can already see that many of them won't. I don't know how successful the 43S can become if it realizes its full potential, but it will definitely depend on how much effort, both in terms of wise design decisions and also skillful communication, is being put into reaching out to a broader audience who aren't HP RPN fans already. |

Something perfect for your presents and the intended scope: find new adepts to the RPN church. ;) Here we are dealing with hardware costing hundreds of dollars. Not something everybody can get an handful of and giving away freely waiting to see if they will be ever used... Still waitin' to be proved wrong, really.

Yes, a device costing hundreds of dollars is unlikely to be given away in great numbers. However, some of those who got a 34S or 31S and liked it, or some who use one of the many RPN calculator programs on their phone, could become interested in the 43S if a convincing case is presented for why it's awesome. Edit: If a nice suite of financial functions is included, it could even be marketed for the folks using the 12C. It's not my goal to prove you wrong. I'm just trying to provide a new perspective and point out that it is possible to win new converts by the merits of RPN alone without relying on nostalgia. But it won't happen if an attempt isn't even made and everyone resigns to the fact that RPN calculator users are inevitably going extinct. |

I agree that adding TVM (and other financial Fns) to the 43S will broaden it's appeal to MANY more potential customers. If even a miniscule fraction of those millions of 12C customers are looking for a better platform, we could instantly double, triple, etc, demand for this machine. This has been suggested in the past (early 31S spec discussions) but indeed was too far from those core goals, but I think fits nicely into the 43S scope, so I for one was quietly happy to see it appear in Walter's recent layouts. I agree it's of lower priority than the core scientific functions, but would suggest basic financial functions are far more useful, and desirable, to a much larger group of potential customers than some of the exotic mathematical features in the 34s even now. Those features surely appeal significantly to a small but passionate group of us here, but the long-term success of the 43S (and successors?) will almost certainly depend on sales volume. Walter points out correctly that TVM, etc. is beyond current competence (at least proven competence) but I do not think it is truly beyond the skills available on the current (and growing) team, plus other contributors on this forum (cough, Gene...). Unlike scientific, engineering and mathematical domains, where calculators have continually expanded features, capabilities and even precision over the years, the financial applications have changed little since the 12C- or maybe even 17B-era. I think these applications are well defined and understood, and there is no need for large investments of time on the UI/Specs. That said, testing is surely a challenge as most of us (MoHPC forum-ers) are more interested in other areas. The good news is that there is a wealth of sample problem data to test with in the endless manuals, books and prior threads here. I would volunteer to do testing in this area. Walter, is it possible to post the current state of the 43S top-level specs and layouts in a new thread? As it appears we are getting ever closer to test hardware, it is useful for the interested members to refresh. I noted that the recent layout (left vs right, etc.) discussions involved many comments that reflected folks didn't understand (or forgot) some basics such as the dynamic menu structure. Lastly, if functions such as TVM are to be considered, would they be "native" (C code, part of the core) or similar to the user-code libraries as in some of the 34S features? --Bob Prosperi |

TVM$ lives in the SandMath side by side with Bessel, Whittaker and many other special functions - and apparently getting along quite well.

RE: 43s status
If anything can be learned from the long continuous history of HP's financial calculators, then this: the customers of those calcs appreciate a clean surface of their problem solvers. Technical people can stand significantly more clutter. Thus I think the 43S in its present draft state will appeal to science and tech folks, maybe also to technical managers (still), but hardly to financial people.
And financial functions are well covered by HP. So I don't see much sense in competing with HP on a field I've got little expertise. I've no idea what I'd change on their financial calcs - in fact, I don't really care. Anybody who wants to take the challenge, however, feel free to take it. And concerning your proposal of a new thread for the 43S: good idea! I will fulfill your wish immediately as soon as I find a prototype in my mailbox.

That's a good point. However, if the financial functions and menus are already in place, it'd be easy and cheap to produce an alternate, financial calculator build of the 43S with different symbols on the keys and a modified firmware with appropriate defaults and UI. |

From the preface of the draft 43S Owner's Manual
Dear user, now you hold your very own WP 43S in your hands. Congratulations! It is a true pioneer: the very first entirely community-designed and -built RPN pocket calculator.
All the hardware, firmware, and user interface of your WP 43S were thoroughly thought through, discussed, designed and assembled, written and tested by us over and over again. We did that to create a new fast and compact problem solver like you did never own before – fully programmable, customizable, incorporating a state-of-the-art LCD, still comfortably fitting into your shirt pocket, and RPN – a serious scientific instrument supporting you in your professional activities! It readily provides several advanced capabilities never before combined so conveniently in a pocket calculator:
We baptized our baby in honor of the HP-42S of 1988, the most powerful RPN pocket calculator available before. May it be a worthy and valiant successor of the HP-42S – though we would have appreciated and even preferred HP making it. In any way, WP 43S stands in the tradition of over 40 years of RPN pocket calculators. ... Enjoy! But remember it's only a draft - especially the numbers 888, 10 000, and 20 000 are subject to change without notice. d:-) |

Very ambitious project sir. Looking forward to it!
May I suggest one more? • Approximately months of average daily use from only one pair of commonly available CR2032 cells. :-) |
