[Oberon] Project Oberon 2013 RISC.img

[thomas.kral at email.cz]

Hi,

I have noticed some changes prof. Wirth made to some modules. History is documented at his website.
I have recompiled modules with recent changes, as the time stamp of original RISC.img is March 3rd 2015, and last changes are dated March 7th 2016.

Now I wish to make backup my uSD card and produce RISC.img.

How can I do it with dd command, as the image size much smaller than 2G uSD capacity?

Many thanks
Tomas
