Good to know.

Quote:The calculator will also run faster when powered by USB.

Nice.

Quote:Finally, you can back up memory in the calculator’s flash drive, so if the battery happens to go dead and you didn’t back up to an external hard drive, you won’t lose your programs and data.

Backing up to flash should be even more convenient than using the USB cable.

I just had a thought. I suppose the operating system (Free42 + device drivers) is also stored on that flash drive. Is there a way to do a checksum or CRC on the OS to verify that it's intact? Does the DM42 have a reset button that forces a reboot?

Quote:Really, the DM42 has addressed all the major shortcomings of the HP 42s.

Looks like it!

Quote:I have also had my DM42 for nearly three months, and am still using the original battery. Just remember to save the calculator state before you replace the battery.

I'll do that.
