Re: DMCP v3.16 ?

DMCP v3.16 is what's powering the DM41X. You won't really see any difference if you update your DM42 with it, there's little point.

Re: DM1X/DM1XL Introduction Dates & Board Revisions

I guess, this technical stuff (and the why behind) would even be great for a short talk/topic at the next Allschwil-Meeting ... 😉 @SwissMicros: what do you think ? I'll point Michael in this direction tomorrow. Are there any DM1xL out there that are powered by a mainboard smaller than rev. 6 ? Was ...

Re: Firmware V30 for DM1x/DM41(L) units

Just a question : what is this version number ? V30 is the latest available firmware version for these calculators. Apologies if that was not clear. My DM15L tells me it's V29 while DM41L reports V28 ! They will report earlier firmware versions until you update them! For information, my 15 lost all...

Re: DM42 won't show up on PC

OK, so we need to eliminate either the PC or the DM42. If you have a USB memory stick or an external hard drive that connects via USB then try those in the same USB socket as you've been using for the DM42. If they show up in "This Computer" or "My Computer" (depending on the O/S) then the PC is OK....

Re: DM42 won't show up on PC

No drivers are required. The calculator has the required code embedded in the CPU and any PC running Windows 98SE or later has usb-storage drivers included. Did you read the thread that I linked to? My guess is a bad connection due to the position of the USB connector in the DM42 and the microUSB pl...

Re: DM42 won't show up on PC

Two things come to mind.

Firstly, does the battery indicator in the top-right of the screen change to a USB symbol when the cable is connected?

Secondlt, this might be worth a read: viewtopic.php?f=18&t=290

Firmware V30 for DM1x/DM41(L) units

Firmware V30 has been released for DM1x and DM41 units. All models [/b] A new serial console command has been added that allows software to place the calculator into bootloader mode via the serial port, which in turn will pave the way for a new updater that can preserve the calculator's memory and w...

Re: [DM10L] The wait is over!

What might be possible would be 79 program steps and all 10 registers. This would require updating the ROM image in the firmware. That's a very good point. It's not going to happen just yet because David has his hands full with work on the DM41X. He's also backporting some of the improvements to th...

Re: [DM10L] The wait is over!

Sorry if this was discussed earlier already, but does the 10L feature a little bit more program memory than the original HP-10C? IMHO, the 10C was a pretty clean design (would have been even cleaner with its secondary functions on its key fronts) but suffered severely under its very limited program...

The DM10L units have dropped in Switzerland and are ready to be snapped up! You can place your orders here: https://www...
