I have and old lime iMac with what I think is a tricky slot loading CD-rom.
I have best results with an old dapper netboot for installing.
However the mirroras have moved and I can't even load a dapper desktop.
Someone pointed me to the hardy mini iso.
Is a little tricky but got it to install.
Problem seem to be having issues with the respository in Britain.
Should I add other mirrors via apt.
