In case you have not seen the pages, here's Debian's page on PowerMacs: https://www.debian.org/ports/powerpc/inst/pmac. There may be some firmware available, but I don't know how to load it during installation with one of the current ISOs. I ran into that trouble last week. Also see https://wiki.debian.org/Firmware and https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/archive/. Jeff
