I saw an interesting Youtube vid on BINET's formula tonight, and what happens in the complex plane if you expand N to the rational numbers. ... A m a z e d ;-) Nice! :-) It would be interesting to see how long the DM42 hardware takes to execute the same program. PS: Could you share that youtube link?

He lives in France, not in the US of A. 8-) Careful... you're dangerously close to being reported :roll: Please kindly consider this forum is luckily located in good ol' Europe where Roman Law was practiced before firearms were even invented and nothing like the NRA exists until today. :D Briefly: ...

I think H2X thought it would be a bit simpler, but this is more complicated. Basically, you can imagine that you "only" store the key codes in the menu table, the 'item'. I improved it quite a lot. The RPN code looks pretty usable to me now. And the fact that the files are less complicated, i.e. on...

Even the ordering of the operator keys is right! I mean correct...

Nice read. Thanx jonmoore. I like the statement below: Having said all that, the engine room of interaction design is habit so regular use of most reasonable device layouts create a positive bias for it's idiosyncrasies. I agree to that statement. I also believe that great interaction design also s...

Great idea but I don't like the fixed filename. Could their be something like: if I specify a flle name like XXX we can save/load the state of the Calc, including the menu structure. And offcourse selecting the menu file by picking from a filebrowser like it is done on the HP41X? I think the abilit...

Haakon, more or less what you had in mind? More or less! I was also thinking about the extra menus for the g-shift labels, since different users might prefer one and not need the other. Or neither, once memory or a proper faceplate makes them obsolete - or if they prefer their own setup to anything...

Amusing, thanks for sharing!

BTW, there's a little section called Background Considerations and Facts at the end of the ReM. Recommended if you want to get some idea why things on the 43S look and work the way they do.

Thanks, Walter, I found that an interesting read!

I don't know about the DM41X, but you can run it on the DM42. The WP43S has an entirely different keyboard, but if this bothers you, you could try the WP43C which has a keyboard layout which is compatible with the DM42 (the keys and yellow shifted labels are the same, and you can get on screen help...
