Well, I'm not talking about WP34S. WP34S is really great, but what if I'm too lazy to do all the cumbersome works of flashing and labelling?
People in this forum are highly demanding towards quality of HP calculators, and yet, the 30b seems to be generally regarded by the forum members as a quality product. I don't have a 30b, but AFAIK, it alreay contains common scientific functions, just buried somewhere inside menus. Therefore, I think it wouldn't be too difficult for HP to remap the keys to produce a scientific version of it. Or is HP already doing that?
Or better still, it would be really nice if HP would buy the invention of WP34S and produce a version of it :)
Scientific version of 30b by HP?

You can buy a pre-flashed 34S plus overlay. Well not at the moment, buy I'm sure it will be available again soon. HP wasn't interested in the 34S firmware when I offered it to them. We've come a long way since then, but I suspect this hasn't changed. I've no idea what kind of scientific calculator, if any, they are working on.

I very much doubt this was the reason. In fact, I'm certain it isn't. We didn't ask for money, the project is open source and hence freely available anyway. We can and would license it under alternative terms if asked -- this has been done for the power saving code e.g. (main.c from memory). The reasons given at the time I asked were: no scientific calculator was on the immediate road map and that the software would need to be re-written to use HP's internal mathematics library. The former clearly changed with the 15C LE, the latter is likely still a concern.

Quote: You mean the library that says log(10^20)=14? (as on the 20b) That's a good plan.

Strange, currently returns 20 and has for several years now. . . TW <edited since I read a 14^20 for some reason>

Hello Tim, hello Mark, I don't get the joke???? Which bases you use for the log? @Mark: 26.5? @Tim: 7.5

I get 21 on my Sinclair Scientific and Elektronika B3-19M. Edited: 13 Feb 2012, 11:22 a.m.

I prefer base 27 for Mark's solution :-)

As others have stated, you can buy a pre-flashed WP34s. The unavoidable problem with the WP34s is that its hardware is fairly anemic and the display is not optimal. What really needs to happen is for HP to commission the WP34s team to decide what the hardware should be like and have them make the firmware. The last time HP tried to make an RPN calculator of that kind, they came out with the HP35s, which falls flat in several important areas.

Is there a supplier of flashed 30b/20b units in the USA? TomC
02-13-2012, 02:40 PM
I plan to provide them in the near future. Actually I'll do it now if anyone wants, but I plan to make it an official listing on my site soon. Probably by the end of the month. Eric
02-13-2012, 03:06 PM
Eric, are you also considering with or without crystal upgrades, or by default all WP-34s' get the crystal upgrades. I think having the upgrade by default is a better choice.

So now you are getting log(10^20) = 20 ? Interesting.

I haven't decided, but I am strongly leaning towards having it be a full-service thing. Ideally it would be a 30b, with the overlay preinstalled, the crystal preinstalled, the latest 3.0 build flashed (or perhaps the last-known-stable build, but I don't know how to determine that), and maybe a printed manual (but as long as it still says "DRAFT" in the watermark I won't bother printing it, and I personally don't think the manual is suitable for printing anyway).

That could happen if you used 10E20 (or 10x on some calculators, although the B3-19M only seems to have Yx).

I'm not sure I understand here. With the current screen a soft key setup just isn't viable. The dot matrix portion is simply too tight for this and seven segments don't work well. The CPU can't drive any more LCD segments so a screen upgrade isn't feasible either. As for more powerful, yet alone significantly more powerful, I'd like to know how so we can implement it :-)

Quote: Version 2.2 would be this. Version 3 will get there, probably fairly quickly though. We've no current plans for major or significant changes after version 3. We've taken the hardware about as far as we can and a lot further than any of us thought possible at the outset.
02-13-2012, 06:14 PM
I'm talking about you working out what CPU and support chips to use in order to properly use a dot-matrix display and somehow getting HP to build that calculator. More memory would be good too.
02-13-2012, 07:24 PM
David; Yes on both. The 34s is 99% "all it can be" on the hardware it is on now.
02-13-2012, 08:08 PM
Drat, I was hoping for at least a v3.5 with a "proper" complex mode per Marcus' proposal. (message no. 14)

I'm pretty sure that proper complex support like the 42s is what we'll aim for rather than the 15c's relatively poor substitute. It won't, however, be in the 30b body. We'll be using something more capable: DIY RPN 5, OpenRPN, the 15CC or something entirely different. We simply don't know at the moment.
02-14-2012, 10:19 AM
Agreed that proper complex support is as on the 42S, with a display that can show real and imaginary or magnitude and angle at the same time. However, I feel that a 15C-style implementation in a device that cannot display both parts (i.e., the 30b) would be preferable to the current wp34s paradigm. But I can see that you would not want to spend any time developing such a paradigm for wp34s if better hardware that will allow the preferred implementation is expected to arrive. |
