A ridiculous idea: what if HP sells calculator hardware & software seperately - kc - 09-18-2009 This comes to my mind when HP decided to sell its calculator emulator on iphone. It sounds great, as one can have a machine with all the good old calculators inside it. But wait, would you ever feel comfortable "pressing the keys" all the way on the screen? I wouldn't. Try entering the Mach number equation on iphone and I'm sure it will drive you nuts.

Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Martin Pinckney - 09-18-2009 Sounds only great to me. I don't think viruses would be an issue; not enough "return on the investment" (glee for causing someone else problems) for the virus-writers. The trick would be to get HP to consider it a worthwhile project.
Oh, and choosing a form factor that would gain widespread acceptance.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Walter B - 09-18-2009 We're not so far away from this. Take the HP-20b as an example. Though its tactile response as well as its display can (and need to) be improved for sure, an interface is given at least. Ceterum censeo: HP, launch a 43S (on your way to it you may launch something blank as KC suggests, if you prefer, but a good keyboard and display are inevitably necessary, as had been said here many times).

Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Frank Rottgardt - 09-18-2009 If I want to drive a beetle I don´t need a Mercedes Benz chassis. Will say the still expensive calculator hardware needed to implement and run advanced functions is a must for the typical 50g customer, but by far an overkill for the 10s type of guy. So where will the 10s mate buy his next basic scientific calculator? Would the 50g guy be happy to subsidize the lower end market fraction by paying higher prices than necessary? Further, the 50g customer expects first class keys, the 10s customer expects nothing from the keys. The latter is used to the simple equation "cheap calculator = poor keys". Will he be happy to pay a higher price tag for decent keys?
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Dan W - 09-18-2009 You mean something like this?
Actually I think the technology could be developed to place some kind of character display on each key and the keyboard so that the function labels could be dynamically changed electronically.
Then one would say, why not just have the flat touch screen like an iPod with the complete keyboard electronic? Two reasons. First as you say there is something inherently superior to a real keyboard. Second, a blend of real and electronic keyboard would have a cool factor - flat touchscreens are so yesterday.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - David Hayden - 09-18-2009 I think HP could get 90% of the benefit of your proposal just by providing keyboard overlays for their calculators, just like they did with the HP 41's. I'm not sure which models currently offer user-assignable keyboards, but certainly the 50g does.
On future models, I think they could also make a handsome profit if they made the machines expandable (again, like the 41). Lots of us would pay to add cool extras (like a printer).

Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Egan Ford - 09-18-2009 Quote:With the exception of #5 I get this with an iPhone and soon any number of touch screen devices such-as other phones, touch screen netbooks, tablet PCs, and eBook readers. If you survey the landscape of calculators out there today and their respective users you'll find that key press doesn't even register as something of importance. However, even small markets can generate revenue. What is the size of the nit-picky calculator market? I avoided the iPhone for a year because of a bias towards Blackberry style keyboards--rigid, inflexible, reliable. However I--as have many others--have adapted to touchscreen technology. The possibilities of virtual keyboards IMHO outweighs the static (even if you can put your own stickers on it). Look at the work done by i41CX+ and 42s. I like the dynamic labels, the on-demand QWERTY keyboard, the swipe for a 4 line stack, etc... I feel that as a whole it makes me more productive.
It's the end of an era, time to change.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Martin Pinckney - 09-18-2009 Quote:Well, fortunately, I do not have to, since I already have sufficient physical HP calculators that I like. Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Howard Owen - 09-18-2009 I would have argued with this if Sam Kim had stuck around. You could at least point to quality improvements in the scientific and graphing models under his watch Now the question is open again in my mind. Focusing on the high school market is presumably the right move for their business, but what sort of quality standards do you need to compete effectively there? What shortcuts in quality would make economic sense in that market and others HP competes in?
Regards Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - hugh steers - 09-18-2009 Hi Egan, The issues of this thread overlap what I am planning to talk about in Denver next month, so I won’t comment. However, your point on virtual keyboards is interesting; I’ve been experimenting with free42 on the HTC touch pro 2. On this device and other latest gen handsets (like iphone), the calculator appears on screen almost life sized – at least big enough to actually press the virtual buttons with your finger. One of the big drawbacks is that you can’t feel the keys. Consequently, I’ve been trying to get some tactile feedback going with the virtual keys. I don’t know if the iphone version does this, but it’s fairly effective (compared to nothing!). Phone people like to call it haptic feedback, but its not really because true haptic feedback involves fingertip sensation (would be nice to add!).
What Im doing is wiggling the vibration mass inside the phone. I’m picking a number for the duration that gives it about 1 spin or so. For me, its 25ms, for other handsets it could well be different. if you’re in Denver, I can show you and that goes for anyone else interested.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Alain Mellan - 09-19-2009 Couldn't agree more with you, Egan. Had a personal iPhone (plus almost every RPN calc that run on it :-) for about a year, and I got outfitted now for work with a Blackberry. The tiny keyboard is totally unusable. I found out the best way use the various calcs for me was to hold the iPhone in the left hand and "press" buttons with the left thumb, while I can write with the right hand at the same time. YMMV. Everybody has different needs and ways to use the machine, and the touch screen seems the easiest to use and customize. Look at the discussions on this forum and OpenRPN.org in the past on keyboard layout. Anybody can potentially make their own with a programmable device like iPhone, it's not limited by the hardware.

Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Garth Wilson - 09-19-2009 Does anyone have any numbers on how long a touch screen lasts? Sometimes I can hardly make the ATM work, and it's not even mechanical-- you can see the conductors for the capacitive sensors when the sun is at the right angle.
One problem with consumer products like the iPhone is that the product life is extremely short-- they're here today and gone tomorrow. If the battery goes out in a few years, there probably won't be one available to fit it anymore. The 41 OTOH was in production for over ten years IIRC, and even today, 30 years after its introduction, you can still get things like Clonix41, MLDL 2000, and of course the older products are available on eBay. I've had programs on mine continuously for over 20 years. In the consumer market you have to move all your programs to another device every couple of years and learn to use it.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Garth Wilson - 09-19-2009 Quote:I believe one of the early ideas or plans for the 41 was to make language ROMs available. That could still be done, couldn't it? Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Walter B - 09-19-2009

My first HP (15C) is still in use and will probably continue to function longer than my 50g and 35s. They just don't make them like they used to. The market has changed to wanting change. Quote:Yep, I did this with my Palms, then Zaurus, then Windows Mobile, now iPhone. Hmmm... also did this with VCR -> DVD -> BlueRay and Vinyl/Tape -> CD -> MP3 and rotary dial -> touch tone -> voice dialing. And, I also did this with my 15C -> 48GX -> 50g. "Couple of years" in this case was ~10 years.
Change is good. Nothing wrong with learning something new.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Egan Ford - 09-20-2009 Quote:That is because you were conditioned to expect to feel it. The next generation will not. Visual and auditory feedback may be sufficient and in some cases mandatory, i.e. a poorly designed mechanical keyboard can give the user a false positive--you'll find multiple threads of missed keystrokes on the 50g and 35s. I'd argue that most pocket calculator users rely mostly on the visual feedback of the LCD. However that all said I firmly believe that there are applications where a real keyboard cannot ever be replaced. E.g. the weighted keys of a piano.
Being conditioned myself for tactical feedback keyboards I'll admit I do miss the feeling at times and that I cannot substitute certain keyboards with a touch screen, e.g. my computer keyboard--the ridges on the J and F are critical for touch typing at speed. I imagine that accountants with their 5 key feel the same way. Perhaps the difference lies in speed. The piano, computer keyboard, Blackberry, etc... need tactical feedback for speed. Most calculator and mobile phone users use a single finger and without thinking register each keystroke from the display--relatively slow work. Quote:Very interested. I think there is a high probability I will make it this year. Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Garth Wilson - 09-20-2009 Quote:Sometimes. But when new doesn't mean better, it's a waste of time. I got a 50g, and totally lost interest after going through the paper manual. The 41cx meets my needs better. So does my 71. Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Palmer O. Hanson, Jr. - 09-21-2009 Quote:What I have found for touch typing is that the positioning of the rows of keys on a slanted keyboard and audible feedback from the keys hitting the platen were more important than the tactile feedback. I went through that when I switched from a mechanical typewriter to an electric typewriter, and again to a modern computer keyboard. When I learned to type on a mechanical typewriter I could do forty to fifty words a minute with very few errors. I held that speed with an electric typewriter but lost it with modern computer keyboards.
In the old days we also had key punch entry machines. Operators never looked at the keys, often (at least as I recall) didn't even have a display, but could achieve phenomenal speeds and accuracy. Engineers didn't need to apply.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Bastian - 09-21-2009 It looks like TI doesn't like the idea of people running a custom OS on their hardware.

Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Hugh Evans - 09-21-2009 Neat idea, but given the cost of development for such an endeavor will keep it from getting off the ground. From some of the posts I've read from Cyrille it could theoretically be possible to get HP to make calculator hardware to the specs of the community... Bankrolling it would be the big challenge, though. How many hundreds of thousands of dollars can HP enthusiasts pool to make that happen?
I'll leave it at that, this could be an interesting thought experiment.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Garth Wilson - 09-22-2009 Quote:As one who has brought many electronic products to market, I am almost tempted to make such hardware myself, if I could give it the time. It would not take hundreds of thousands of dollars. For NRE (non-recurring engineering costs), figure a few thousand for a custom LCD (we looked into it 20 years ago and were quoted about $2K, and I suspect that greater efficiency today means the price has not increased much), or maybe better, use an off-the-shelf LCD to avoid the NRE, a few thousand for the keyboard (we looked into that too, with double-shot keys so the labels are actually in the keys like the HPs' of the early 80's so they won't wear off), a couple thousand for lexan overlays (we've done those), a few hundred dollars for the first run of PC boards (we've done loads of those, up to 12 layers, but 2 to 4 would be plenty for this), and a few thousand for the case molds. I lay out very dense PC boards all the time, SMT and thru-hole, and up to 500 parts on a single board. Add in the parts for the first run, and we're only up to about $20,000, plus my own time.

Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Egan Ford - 09-22-2009 Quote:Much of that time is probably spent on software and documentation. I believe that is where the hundreds of thousands comes from. A single engineer's salary can easily exceed $100K US. And, you need to double that to get the actual carrying cost of an employee (at least in large companies).
I have a dozen incomplete personal projects sitting on my desk (I'll bet Eric has 100 :-). Time is a rare and expensive commodity.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Garth Wilson - 09-22-2009 I was figuring that the community of enthusiasts would do the software. I'm happy on a fraction of your $100,000/yr though.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Hugh Evans - 09-23-2009 My quote of hundreds of thousands was in response to HP taking on the development of said hardware. Your figures are correct. LCDs in many cases waive tooling fees now, injection molding costs vary more than I'd like. As a cost cutting tool, I worked on a procedure for OpenRPN to accomplish the effect of double-shot keys using laser etching with a resin back-fill for key legends. It's a trade-off in terms of cost vs. flexibility.
If you ever want to pursue such an endeavor I would be happy to donate my efforts to see it happen. OpenRPN, for me, was always about bringing at least one more great no-holds-barred piece of calculator hardware to the market.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Hugh Evans - 09-23-2009 I've pondered this issue before. Looking at the body of work already available from nonpareil, free42, x48, to name a few. Creating hardware capable of running said software would be relatively trivial.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Eric Smith - 09-23-2009 I imagine that a few of the reasons that TI isn't happy about installation of non-standard firmware on their calculators might be:
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Bart (UK) - 09-24-2009 Has anyone tried reporposing a 20B to a 42S, to replace, as it were, the aging hardware of current user's 42s's? Doing the same as what HP has done with the 12C+ could give a faster 42S with new harware. Just a matter of re-labelling the keys, I remember someone posting that they were struggling to remove the original lettring from the 20B keys?
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Tim Wessman - 09-24-2009 The big problem with trying to do that, or to make any scientific out of the 20b is the screen. The LCD driver built into the chip will only support 400 segments, and they are all used on the 20b. It could be possible. . . but I'm not sure how it would turn out. :-(

Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Mike Morrow - 09-24-2009 Quote: Sounds fishy. :-)
Quote: IMHO, such alterations to existing hardware would be a big-time kludge of interest only as an experiment. How would the 20B display be made completely compatible with that of the 42S? What about generating 42S sounds, which can be important to prompt for input? What about IR printer support? If I lost both of my HP42S units, I'd use my disdained HP32SII before falling back on a Franken-42S. Actually, I'd accomodate the large size and just use a 50G. But I've used one 42S daily for 12 years and it still looks and responds like new, while the other is yet new in the box. The 42S has kept its youthful appearance much better than my HP-15C did after only a few years of routine use.
But a new HP42S-type machine designed from the start in the HP20B-type hardware (but with sound and IR) would be interesting indeed. Much better than any mythological HP-15C re-issue, IMHO.
Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Jeff O. - 09-24-2009 While not optimal, it seems like the display could be useable for a decent scientific calculator. The dot-matrix area in the upper left side of the 20b diplay could be used as a rudimentary second line, to display the stack-y contents and/or to display the imaginary part or angle for a complex number representation. Last year after HHC 2008 when the 20b repurposing project was active, I played around to see how numbers might be represented in the dot-matrix area. Below is what I came up with. Of course I have neither the knowledge nor the equipment needed to repurpose my 20b, so that's as far as it got.

Re: A ridiculous idea: what if HP sells calculator hardware & software seperately - Mike Morrow - 09-25-2009 This LCD would be completely unsatisfactory for an HP42S type of calculator.
