WARNING, you are going to modify your system with older drivers from debian 8.11(jessie), you have been warned!
WARNING YOU MUST HAVE 1GB OF RAM ON YOUR iMac G3.
This guide is intended for "who doesn't want OpenBSD and who are pleased not to have graphics acceleration on their mac" YOU ARE WARNED!
Hello, in this guide I will show you how to get the gui on iMac g3 with debian 12! here some example of it:
1)

To get this we need to follow these steps:
1) [first, the system must don't have xorg or a desktop environment, with the netinstall, install a clear system without xorg and desktop environment, if you install it you need to remove it completely, now follow the guide] we need to downgrade the Xorg and video drivers(r128 driver), how? well, I saw that these drivers work from debian 8.11(aka jessie), and how we can install they? first, remove completely Xorg and r128 drivers from your system, after that put in your "sources.list" these repository (from archive.debian.org) and comment the debian sid repository, after that do "sudo apt update".
example of what your sources.list should look like:
2) install all these from debian jessie repository
after that, you need to hold these packages to avoid problems in future, to hold do:
3) After the imac g3 end to install all of these packages, fix the sources.list by commenting the debian jessie(8.11) repositories and putting the default ones back, now do "sudo apt update && sudo apt upgrade"(by hold those packages before, you can install new packages or upgrade the system without problems)
4) For the last one, to make work xorg just generate a xorg.conf with "Xorg -configure" copy the result to "/etc/X11/" and now modify these sections:
the xorg.conf file will look like this
5) Install a desktop environment or a window manager and enjoy your new system (without graphic acceleration...)
ENJOY!! (If you have any problems or I forgot something let me know)
