Thanks to a very generous donation by IBM we have now a new porterbox for powerpc and ppc64 (big-endian) available [1].
Am I right in thinking you mean powerpc as in the 32 bit BE architecture dropped as an official port after jessie, re-activated as an unofficial one in 2018, suitable for use on "new world" Apple Macs e.g. some Mac Minis etc.?
Great news if so, thanks! -- Jonathan Dowland
