[Qt-interest] [slightly OT] Null device with Qt

[alexander golks]

good morning!

please see attachment for the datasheet of the random access write-only memory
which can also be used as null device in case you don't have one on your board.

hope this helps, too!

after all, and it is a mere operating system.
