So you think that the day Microsoft doesn't deliver updates anymore, all of a sudden a computer stops working?

On the contrary - sooner or later it will even serve more users than you think!

But: grsbanks said the IR protocol is implemented in the DMCP OS, which is used by the DM42 as well as the DM41X.
So I don't see how a DM41X ROM would help here.

Nice

I want one, too.

Hi, I'd like to do some tasks regularly (let a cursor blink, for example), but still spend most of the time in a power saving state. It seems like sys_timer_start(timer_ix, ms_value); sys_sleep(); sys_timer_disable(timer_ix); would fit the bill, but I don't know if I can just choose any timer or if ...

That's great, thanks!

I don't know how much current the DM42 draws, but for standard USB compliance you'd have to provide 500mA at 5V. That means you would need at least 25 of these, and above that you'd need either a boost converter to get to 5V from the 3V you (ideally) get, or you connect the panels in pairs to get 6V...

Hi,

any HP/SM calculator enthusiasts visiting the 35C3?
Maybe it'd be nice to have a little meetup?

Cheers

Thank you!

PS: I do have a DM42, though. I assume the emulator and the "real" calculator firmware (will) share the same code (minus some of the UI, obviously)?
