Hey all , I've been unavailable to work on hobbies for a number of years but I now have some time again for a bit
and I was hoping to work on an iMac.
I was wondering if anyone has done this same hack but with a iMac slot loading G3. I've made good progress with help
from people over at macrumors but I was hoping that someone over here might have some info on connectors and boards.
I'm putting together diagrams with pinouts and would love some input.
Below is a link to the diagrams and code.
I've also included videos with my progress at the bottom of the page.

At the moment I/m looking to find out how the down converter board gets its power and what the pinout is for the
earphone jack.

Thanks in advance.

If anyone is interested or has more info in the way of sniffed comms between the iMac G3 DV logic board and the IVAD board
please share.

With lots of help, Ive gathered enough info to make three printed circuit boards to convert the iMac G3 DV into a CRT monitor which can
be used by a regular computer with a VGA out.

here is one of the videos.

Here is the link to the repo.

I forgot to post here.

Here's a video of me disassembling a working iMac G3 DV and fitting in the boards to turn it into a monitor.
At the end I play Minecraft with it as the monitor. BTW this is a non destructive mod and it can be easily reversed.
