Re: DM42 "USB Disk Mode" works at random - mostly not at all

Yes - both the sharpie, cable, calculator and my fingers survived the operation, and now the DM42 connects every and each time! My cable was blocking both above and below. I tried to first remove a wedge at the top, but that wasn't enough, so I removed all the way arround the socket. Approximatly 3 ...

Re: Astronomy OFFIMG's

Great pictures as before! I think NGC6946 is better suited for offimg display than the horsehead. Agree - the Fireworks Galaxy looks better. That's quite a serious telescope you have in your back yard if you can image the Horse Head Nebula like that! :) Please do share more such images, lots of fan...

Re: DM42 "USB Disk Mode" works at random - mostly not at all

Update: If I press the USB plug hard, like really hard, into the DM42, it connects. I use this same cable for several other devices, so I don't think the cable is broken. Have also tried the same with my other cables. It's the same, need to apply a lot of pressure.

DM42 "USB Disk Mode" works at random - mostly not at all

Do I need a Windows 10 driver for the DM42? Since I got it, it's been very sporadic weather I could get access to my DM42 on Windows 10. Usually I just have to retry 2-3 times, then the connection succeed, but now I have tried a dozen times without any luck... I have tried several cables, they all w...

Re: DM41X Unresponsive to RESET action

Isn’t there also reset buttons inside on the PCB?
I vaguely recall having seen that somewhere here on the forum. But they might just be the same as can be pressed from the outside?

Re: DM41X Unresponsive to RESET action

I’m certain that removing the batteries will eventually switch the calculator off ;-) No idea if it helps resetting though ;-) Back in the early 80’s, I remember that when putting my HP-41CV into synthetic mode, it could hang. Removing the batteries didn’t help immediately, probably due to some capa...
