Re: DM42 vs DM43S

The current solver is a keystroke program fairly close to how the calculator is programmed: https://sourceforge.net/p/wp34s/code/HEAD/tree/trunk/xrom/solve.wp34s The main differences in this case are that: the user's function is called using the sequence XEQUSR immediately followed by POPUSR the sta...

Re: DM42 vs DM43S

The thing I dislike the most about the wp34s is the lack of a built in MISO solver. Feel free to donate such a solver to the 34S project. I'm sure a keystroke program would make the standard library. It might make XROM with enough care. A C implementation including the ancillaries, would most likel...

Re: DM42 vs DM43S

As far as I'm concerns DM43 == WP43S. This is at a minimum two years from completion and very likely more than that.

Re: Why was Stainless Steel used for the DM42?

Why then do the stainless steel screws I use break far more readily that the plain steel ones? Stainless steel ones seem to break as easily as brass or even more easily. Stainless has other properties that make it difficult. It work hardens quickly and my previous employer had to press enclosures mu...

Re: 43S News

I'm confident HP did some investigations before changing the keyboard layouts with the launch of Pioneers -- assume the gains by following a logical order of operators outweighed the losses by hidebound traditionalists. I'm not. Big companies often do bizarre things for no intelligible reason. Pauli

Re: Troubled waters

AFAIK (I'm no SW person) we will handle the 43S as far as possible like we handled the WP 34S . I.e. our code would be as public as the WP 34S code is. I'm not aware of any code from anybody else needed for the 43S yet. We'll need hardware support code and this would likely have come from DM. I dou...

Re: buttons that don't register well

I've got a couple of keys that don't always work and one (7) that sometimes works, sometimes misses and sometimes double registers.

Re: 43S News

... and it's even viable. :) Just for logarithmic fits you loose a digit more, meaning output of fit parameters will have a somewhat limited precision but sufficient for the real world by far. Is a size reduction possible for the fit equation? Split it over two lines? Rename a0 and a1 as a and b? O...

One small suggestion: show the equation underneath where it says "Power*", if there is room.
I like this suggestion.

Re: 43S News

If the 34S is a guide, a couple of years to go :(
