I would like to install Debian 8.7.1 on an older Mac iBook. However, the install disk (debian-8.7.1-powerpc-netinst.iso) will not boot, but hangs at the beginning (after I have hit ‘C’ twice for “boot from CD”). The iBook can boot, as it will boot CD’s with Ubuntu 16.10 and MintPPC11 (but those installations fail later, with other problems). It is the Debian CD that seems to have a problem with booting. Is there an older version somewhere that I could try?
