Re: Load/save extended memory files from/to FAT

I'd really like to have this feature too. It would make the calculator quite handy for collecting data and then exporting a file that could be loaded into Excel or the like for further manipulation. If all goes well, you'll both eventually be happy! :) But I can't say when, and absolutely cannot co...

Re: Memory management?

Thanks Thomas, that sounds pretty close to how I imagined it works.

Re: Memory management?

I've noticed some odd behavior in the DM42's reported free memory as well. I'm guessing (i.e. I haven't read the source) that Free42 is just reporting the amount of memory that OS tells it is available, in other words however much it could malloc for its own use. You'll notice that editing a program...

Re: Why not a DM17BII?

I'd be pushing for a DM71, personally. ;)

Exactly emulating behavior which isn't particularly useful...
I'd wager you could find plenty of disagreement on this point, particularly from fast typers.

Re: DM41X V2.1

The update installed just fine. However, two-key rollover appears to still be not working correctly (same behavior as the previous version). e.g. hold 1, press 2, release 1, release 2, and you get 122 on the stack.

Re: Delivery to California USA

There currently is no priority shipping option with tracking, though very, very few shipments have ever been lost. Shipping from Europe to International addresses with tracking is dramatically more expensive than the current rate, and is often not much faster, sometimes not even as fast, due to ind...

Re: Memory usage changes?

unless the state files are heavily compressed. They are not. The size of a state file is roughly the same as the amount of memory it takes up when loaded. Programs about double in size when loaded, while the overhead for other data types is much smaller. Okay, then the disparity isn't QUITE as stri...

Re: Memory usage changes?

A little more experimenting: I flashed my older unit back to the 3.15/3.14 firmware (July 2019), loaded the state file, and had about 35K RAM free. Then I created and stored a 640x3 matrix, leaving around 3K free. Then I did GTO .. and the calculator crashed, flashing something on the screen far too...
