To be exact: * powerpc is the original 32-bit port; BE; it _was_ an official release arch but as of stretch has been relegated to second-class status * powerpcspe is an incompatible arch, 32-bit BE, second-class only * ppc64 is 64-bit BE, it at a time looked like it's going to become a release arch but has never made it; it supports quite old CPUs * ppc64el is 64-bit _LE_, requires POWER8 (there are some LE POWER7 machines, unsupported); is currently the only official arch All of these but ppc64el have quite regressed. There are rumours that IBM people have actively pressured a bunch of upstream projects to drop support for older CPUs. This is unfortunate for the laptop project you're talking about, as, as I understand, they run ppc64 kernel with powerpc(?) userland. This means BE, which has no longer official support. I've never put my hands on any PPC machine, though, ssh and qemu notwithstanding, thus my knowledge here is only second hand.
