Re: DM16L memory question

Yes, it would technically be possible (maybe with some limitations like not being able to address the extra memory directly). And the DM1x models all use the same hardware so you can flash a DM15 firmware in a DM16 and it will work, only all the key labels wrong (of course). I don't know if that als...

Very interesting. Does the simulator extract and insert individual programs in the dumps from the DM-15, or did the simulator author find some other way to do it?
The exported data is put in a single human-readable textfile where all programs in the DM15 are stored as one large listing.

Re: May 2021 Speculations

I have studied physics, and I have NEVER been in a written exam with a calculator allowed where the availability of numerical tools would have been helpful to gain enough points to pass. I have. I studied applied physics and I still have nightmares about my linear algabra 3 exam which I had to do 7...

Re: Upgraded keypad

How do I know if I have an old or a new keyboard? My DM42 has serial number 05370, is that sufficient information to tell?

Re: Does the Free42 2.5.18 update effect the DM42?

The 2.5.19 update and the changes in current master do affect the DM42 and are just small bugfixes, so they could be quickly implemented in a new firmware version.

Re: Do not use Firmware V30 for DM1x/41

I had the same issue: I had recently ordered a DM15 that came with v30, and it took several tries before the firmware update tool recognized my calculator but I finally succeeded in flashing v29 firmware. I used a mini USB cable from an old phone. I just ordered a DM15L and got confirmation it was b...
