  No need for a CD drive: tried to load a live or installer linux via
some USB thumb already? Instructions:

https://marc.info/?l=openbsd-ppc&m=155231977928919&w=2

I did complete installs (32-bit) this way ...  I have no idea whether
the Debian installer has that "nvsetvol" tool on board, but it might
be worth a try.

Maybe try newer Debian images, or try somewthing like

boot [some usb pattern here??]:,\\:tbxi

see:
https://lists.debian.org/debian-powerpc/2019/05/msg00112.html

lubuntu live:

http://cdimage.ubuntu.com/lubuntu/releases/16.04/release/

And I'm not sure whether this image

http://cdimage.ubuntu.com/lubuntu/releases/16.04/release/lubuntu-16.04-alternate-powerpc.iso

is 64-bit or not.

Thanks for the hint - but maybe you *might* (be careful, I'm not an OF
expert) need to save the changes to nvram:

see:
"
  [to save the results into NVRAM]
  reset-all
"
from:
https://ftp.openbsd.org/pub/OpenBSD/6.5/macppc/INSTALL.macppc

Good luck!
