Multiple problems on installing Debian 7.8 on PowerPC g4
 

I'm trying to install Debian 7.8 on my eMac G4 (700mhz, 640 Mb RAM). I've tried multiple methods but I keep running into problems one way or another. Since my eMac only has a Sony CD-RW drive and a busted Ethernet port I can't install from a DVD nor a netinstall CD which would be the easiest options unfortunately. First I tried using the multiple CD option, which seemed promising at first; until I had to swap to the next disk during "configure the package manager". it won't eject the CD when I use the eject key on my keyboard (imac g3 pro keyboard so I go back to the main menu and select the "eject a CD from the drive" option at the near bottom then things seem to get clustered. When I tried inserting the next disk, nothing else will install. It keeps telling me I need disk 1 again through every step. Then at the end, it tells me the installation is complete before I even install a desktop environment from the final CD. Then I just end up booting into garbled text and errors.

After all of that nonsense, I tried making a bootable USB from the DVD ISO with the OS X terminal. This method usually works with just about anything I've done before. However for some reason Debian apparently simply refuses to boot. As I tried selecting it on the boot menu on the start up, it gives me a black screen then goes straight back to the boot screen with disordered graphics. When I tried booting it from open firmware, it goes to the first screen, then when I hit enter to actually boot to the installer, nothing but errors. Finally I tried booting it straight from the ISO file on the hard drive, that method didn't even work at all.

Could someone point out what I'm doing wrong if possible or perhaps recommend me a different option?

I don't know much about the Debian installer, but did you check the md5sum of the install media? I may be wrong but during installation it can ask you to insert another CD and then the previous CD again. It's because if some dependency packages are on, say, CD2, then they would have to be installed first. After it's done with that, it will ask you to reinsert CD1. You are just gonna have to go along with that.

A quick search brought me this guide. So it's been done. Good luck.

Which commands did you use to achieve this?

The Debian installation guide suggests using plain old `cp`

I have zero experience with Macs though so I may be completely wrong here.
