Hello,
is DM42 schematics a proprietary thing or it is available for public domain?

You may find some information in this thread: DM42: The internal view (hardware components)

Sorry for the double post ... my IPad is still :(

But It doesn’t sound differently : DM42 hardware is something « proprietary », or do your own implementation but soft without hardware will be something unreachable...

Just my opinion.

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

If I missed something, the best would be to ask Michael... I am not SWMicros authorized, but being SM I would not « allow » any hardware copying.

Once again ask Michael, but I am sure there is some patent not only about Hardware but too about Firmware and honestly who would support this ?

We all support SwissMicros, who would buy a clone? Do you have any subcontractors in China ?

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