Re: "Empty" DM42 units

Thanks for clarifications! It is possible that I did remember it wrong.

Even I could imaging an emulator of famous Soviet RPN calculator MK61 to be running on an amazing HW as DM42 :)

"Empty" DM42 units

Hello,
as far as I remember some time ago there was a discussion about a kind of "empty" DM42 HW - without bootloader, firmware and keypad engraving, so one can buy for cheaper price for DIY purpose.

Did I miss something?

Re: DM42PGM build

What about Windows Subsystem for Linux in Windows 10? I have switched there for all of my hobby projects. There is a good Tutorial how to set up Microsoft Visual Code for Remote development in WSL.

In fact I did not try to build anything DM42 related in WSL, so maybe it is a good time to test it :)

Re: DM42 battery life time

Thanks! Indeed my selection of the battery was not a best one :) But I will keep measurement for a while, then will switch to something reliable

DM42 battery life time

Hello,
I started to log the battery voltage, roughly once a week. Without using the calculator at all. So, switching it ON once a week.
Is this a a normal discharging curve?

Software is 3.18

Re: DM42 schematics?

My question was mostly out of curiosity - I'm not going to manufacture DM42 clone nor copy it in to e.g. HW emulator :)

Re: DM42 schematics?

Some part of SW is open, according to the license.
