I recently got an old PowerPC CRT iMac. Here are its specs:
Mac OS 9.0
PowerPC G3 400 MHz
I'm trying very hard to install some form of linux on it, but am stumped because the optical drive is broken. I also tried installing from a USB thumb drive with boot.img.gz on it, but that didn't work.
I have another PowerBook at my disposal, but I can't put the iMac in Firewire target mode and install using the PowerBook because the iMac's firmware is not up-to-date. Unfortunately, I can't update the iMac's firmware because that requires Mac OS 9.1 or Mac OS X (the iMac has Mac OS 9.0).
I tried to use an external USB optical drive, but the iMac doesn't support booting from external USB optical drives.
Is there a way to install Linux (preferably Ubuntu) onto this iMac?
Thanks for helping out a newbie!
