    Thanks dude. I have heard that a few US schools STILL have rooms full of the eMac as a dead weight. It will be a interesting "Science Project" to hack this lovely machine for being used again (But don't think that will happen: Imagine the teacher saying "Oh, and don't touch the CRT: You will be electroshocked until carbonization")

    I love what you've done here Rocky and have begun to also do something similar (Albeit with a Dreamcast). I have run into a little issue though and was hoping you'd be able to help.

    Following the pinout guide on Headless Mac I have pinned my own VGA connector but left some of the wires attached to the original plug (I2C) which is still connected to the mainboard which I was hoping would still init the CRT but unfortunately does not.

    Yellow = Still connected to the main motherboard header.
    Red = pinned into my VGA connector which is connected to a Dreamcast.

    Any idea as to why the CRT is not initializing? The system itself powers on.

    Thanks in advance.

    [EDIT]

    Further thoughts - The monitor is initiated via the mainboard during standard boot but it's possible that the system has detected that the VGA is no longer connected and in turn is not sending the initiate signal.

    Today, the eMac CRT showed EL Capitan, sharp clear and beautiful, for the first time in history (And i´m not able to upload the picture from my smartphone).
    The original logic board is on a side of this room, on the floor (No need for it anymore).
    The setup runs a Mini-Itx mobo Asrock H81M-VG4 r2.0, 8gb ram, Celeron 1820 processor (Can´t pay much more, sorry), and dedicated Pci- express Ati graphics Card, all of this well fitted inside the eMac Chasis.
    I promise pictures, videos and tutorial for this.
