A new HP calculator group?!?


I just read the following at http://www.magpage.com/~jakes/video.htm:
A new HP calculator group based in San Diego announces its intentions to resume calculator development.
According to the latter website this was announced at HPCC 2002 Handheld and Portable Computer Club Twentieth Anniversary Conference in London.
This is some very nice news...
Does anybody out there know more about this (sadly I'm not a member of HPCC, at least not yet...)


Yep, heard the rumour before the conference. But I do not believe it before it's going live.




I belive we have an HP95C's photo (right, 2nd. row) at the page mentioned by JHonny. I read about it and I thought Dave Hicks had the only one existing.

Is this the one?

Just curiosity.



I know of several others besides the one I have. There were either 50 or 100 made and a significant number seemed to have escaped.


I recently received an urgent request from HP to send some manuals to their OEM in Taiwan. Fortunately, no one asked me to keep this confidential, although I think I should avoid specifics. I'll just say that the requested manuals were for RPN calculators and most were scientific calculators. Of course, this could mean... well anything really.


You should have only sent manuals for the higher end RPN's so that they wouldn't benchmark themselves on the lower end units (ie a 42s and/or 28s) so that any new RPN calcs would be compariable to the higher end pocket calculators we all want. 8o).


Hi Ron,

One of the types of calculators I would like to see IS something equivalent to an hp32sii with RPN without equation storage, and without programming, but WITH equivalent memory storage, and the constants and conversions in the hp30s.

Such a calculator should be inexpensive and would be permitted on a wide variety of tests where more powerful calculators would not be permitted. It would also be an easy entry level into the world of RPN calculators for students.

To be competitive and desirable, this calculator would have to include fraction capability as on the 32sii or as on the 30s.

Of course, I would like the more powerful calculators as well.


Clarification: The same number of memory registers [if not more] as the 32sii.


rsenzer: "without equation storage" NOOO, please. The solver of the 32sII is one of its best.
rsenzer: "and without programming" Again NOOO, please. With MORE memory for programing. Why shorter memory than in the 15c? I've never understood that. What about 2Kb? 8Kb?
Best regards


Hi Raul,

This is designed to be a stripped down model not the mainstay for an RPN line. Many instructors will not allow calculators with the ability to store formulas or programs, to be used on tests. This may be a "first" calculator for many students and as the need arises, they would buy the more advanced products. Although I did not mention this, I believe that this low-end machine should be dual powered -- i.e., battery and solar, since it would be used frequently during tests. I would expect it to be cheap and small, i.e., sized like the 6S or 12C.

I suppose you could still allow formula entry, evaluation, integration, and solution of an algebraic equation/formula entered on the display line, even though it would not be capable of being stored. But this might raise the cost beyond the scope of what I have in mind. In fact, it could be dual mode, allowing for RPN or algebraic, but I know where I want to see the "ENTER" key.

I still wish to see more substantial RPN products similar or better than the recent RPN lines that have been discontinued. Such new models should have more than one line. [I have not used the 2 line 42S, but I do have a 19BII and I like the multi-line display there, although it would have been nice to have 4 lines on that particular model in order to see the T-register.]


I did whine a little about the fact that they didn't request my favorite. The response was "maybe next time".


....of the man who has everything?



after what I read from Joerg, I think there is no big deal to transform and SRP400G into an RPN calculator. I believe a reversed engineering process begins with the specs of the equipment to be "reversed-egineered". People in Taiwan should first know how does an RPN calculator operate, so they could adapt an existing operating system to do so.



Perty sure that the Koreans could lay their hands on some real rpn machines at any moment... HP or Elektronika or some simulation on a PDA... and as most engineers at the OEM are likely familiar with stacks and such, I'd find it INCREDIBLE if anybody working for a calculator factory needed to "bone up" on the user-end elements of an RPN interface.

What I *would* find credible is that HP is looking for the OEM's documentation to reflect some of it's own earlier instructional glory. HP asked for docs it had long mothballed, but as examples of what it wants the documentation to be like on the next models. If HP asked for docs of RPN calcs, HOPE is there... AND the implication that HP itself is taking the idea of instruction books seriously again, after a lull of several years.

This could be VERY GOOD news all around-- thanks Dave. You've made my week.


Hi, Glynn;

I agree with you an RPN-like device operates much like any average uP, and developing a calculator's RPN-based O.S. is, I think, easier than and A.O.S.-based. What I've been wondering about is that the HP interface is brilliant, because it bonds simplicity to power. And I think that this is something they are probably trying to rescue, too. As you mentioned:

"(...)the implication that HP itself is taking the idea of instruction books seriously again, after a lull of several years."
Do the Koreans have this feeling? Anyway, Dave mentioned Manuals to their OEM in Taiwan, not OEM manuals to Taiwan, right? Is it correct, Dave?

It's a fact that programs developed in an RPN-based O.S. machine are hard to debug, but daily use has proven it's not hard to use and understand (see HP12C's still). Maybe they want the new models to have classic RPN interface, and the best way to develop the interface is learning how does it work and what it can do.




Yes Taiwan - these folks to be exact

They also make:


Yes, Kinpo works with Citizen, Casio and TI too:


Is it me, or under CE appears a TI 30X after a time?

'Clone war, began has'



Indeed, a TI-30X IIS: Compare this one http://www.kinpo.com.tw/images/114.jpg and that one:
Regards, Joerg


If the calculator OEM needs help with RPN, "compatability testing" perhaps, I'm sure that some of us here could lend them a hand :)

Beta testers, anyone?


I am a volunteer!


dave; did you send them the product specs for the 67c/cx or (be still my beating heart) the 68wx? humor doesn't translate...you never know; they might just build one.

seriously, thanks for being there for them to ask info from. you may have helped get us what we want. still; it's a good sign but a strange one that the company that invented the genre has to ask a collector for help to start building them again.

glad they did. glad they are. - d


I should have sent that and pointed out that some people tried to order it at $399, 26" magnetic cards and all ;-)



We can always dream -- can't we? 8^)



I really don't know about this Video, but the clear cover of the HP-9x and the Classic one is cool. Where can I buy such a cover?



Maybe ask Mike (ipscone@msdsite.com) or another mass reseller with good sources;-)
