Hello to everyone.
I have a working eMac logic board from a CRT-dead unit, loaded with 1 Gig of RAM, 80 Gb HD and Pioneer DVR-105 DVD recorder.
I'm planning on using it to build a file server-desktop computer, but I need the info on how to power it up.
I've been looking all around the web for info and ideas on how to provide current to the mobo.
The other day I found a web page that performs a technically wonderfull iMac ATX conversion (http://www.ct-scan.com/iMacATX/).
Before finding this web page, I thought the eMac motherboard SHOULD be powered through the "Blind-Mate" connectors available in the logic board, so the down converter board should make it's work of providing the necesary current to each part of the logic board (including both drives power headers). This led me to the problem on HOW to measure voltages in both "Blind-Mate" connectors (only one in 2nd and 3rd generation eMacs) without the Analog Module (I don't have it).
NOW, after seeing this iMac ATX conversion, the idea is to power the logic board directly through the Down Converter Board's connector, which is the path followed by the author of this web page.
Here goes my question:
The IMAC down converter board connector has 24 pins, all ordered and compared to its ATX counterpart in the diagram available in the web page, BUT the EMAC down converter board has 20 pins, and this is where I have problems when assigning each pin with its ATX counterpart.
Now, I'm BEGGING anyone who could have access to an eMac (better if is a 1st generation one), to measure each pin voltage in the Down Converter Board connector, and post this info, because this is the only thing that stops me from using a wonderfull eMac system with an ATX PSU.
