Re: buttons that don't register well

Hi Cesar, only to check whether I have understood your hack correctly: You put this two pieces/stripes of post-it above the left or the right dome of the ENTER key (looking at the DM42 from the front side and the calculator oriented with the usb pointing away from you) ? Thanks a lot for the hack! ...

Re: Inconsistant way of editing LBL and GTO targets

Hi, another idea: In both cases (that is LBL and GTO): Let the user decide. Pop up the alpha menu and stay in numerical input mode. When a menu key (top row) is pressed, change in alpha mode and "return" the according label name. If a new alpha string needs to be entered, do what you usually do: Ent...

Inconsistant way of editing LBL and GTO targets

Hi, In a valid program each GTO corresponds to a LBL. Therefore I think, all LBL and GTO should be editable the same way To explain for what I want to suggest an improvement is this: Start a new program: Enter the global program label. Now enter GTO. No alpha mode is activated and you can enter numb...

DM42 hangs

Hi, this is a somehow incomplete error report: I managed to hang my DM42 by browsing the included help pages. It happens while moving up and down quickly (I confused up and down for a moment and switch the direction fast to correct me). I had to trigger system reboot. No program was lost from RAM, t...

Hi, The following is done with the HP42S-font set for the display [Yellow] ENTER (Alpha) [Yellow] SST (to set [A]) [Yellow] x (multiply) ...and you will get an "*" (star) in the Alpa register on top of the LCD. Doing [Yellow] ENTER (Alpha) [Yellow] SST (to set [ ]) [Yellow] x (multiply) ...you will ...

Driven by curiosity: Is it only me or is it the glass actually?

Hi, every time I touch the Gorilla glass of the DM42 screen I think..."...that feels somehow different...somehow 'smoother'". (compared to ordinary glass of a window...that one without that gorilla...you know... :) ) Based on physically parameters ;) gorilla glass should feel much harder...in my opi...

Re: buttons that don't register well

Hi, I had some kind of a partly sucessful hack of some sort ... (being careful here... ;) I measured the resistance of the foam on the battery holder...infinite high. So I think its purpose has nothing to do with grounding static electricity. To get rid of one point where the PCB may get bend due to...

Re: buttons that don't register well

Hi,

I think it's not the ENTER button...the hole thing
isn't plane as it seems to me.
On the lower part of that photo take a look
at the "STO"-button and compare it with the
"R(down)"-button for example...

Only my two buttons...your buttons may vary... ;)

Cheers!

Re: The Solver and the Golden Ratio / Golden Cut

Hi ijabbott,

OH YES! Thanks a lot...until now, I thought the X-value (as the the "x" in f(x)) is
also in the x-register of the stack when the function is called, which should
be solved.
Seems not to be the case.
Thanks for the hint -- now it works as exspected (tm) :) !

Cheers
