I’m so sorry it wasn’t clear. I used Power architecture before, so I have experience with this. I also use the Raspberry Pi Desktop on X86_64. It screamed that the project may won’t work. But it’s running. With the BOINC community it’s a great idea, maybe it’ll get TO on the map of another interesting project. On the World Community Grid forum there is some thread about rpi3 https://www.worldcommunitygrid.org/forums/wcg/viewthread_thread,39145_offset,20#539212
But, it is question on someone from the team @mpetracek, if we can use the *.APK directly on TO?
