I have a 98 g3 tray loading imac, the motherboard doesn't work anymore. But apparently your monitor is still fine to use. I thought about turning it into an iPC, because I have a Dell Pentium 2 notebook that the screen broke, I would use it to replace the imac motherboard.

From what I've seen on the internet, this model should simply work as a vga monitor without much modification, it uses a DB15 cable that connects to the imac's motherboard, but this DB15 connector is arranged differently from the traditional vga db15 connector. I then took a DB15 female connector compatible with the Mac output, and a traditional female VGA connector, and connected the wires following an electrical schematic. The scheme was to do the reverse (use a vga monitor on a mac) but I was unsuccessful.

Does anyone have any tips?

I know what you guys are going to say, buy an adapter. The problem is that in my country they don't have it, and I don't have to buy it in another country, so I need to make one.
