Instructables
Picture of The Apple DVI to ADC monitor adapter model A1006
First, a standard disclaimer -

You could get cut getting the sticky plastic label off.  It's possible that while opening up the white case you will get a nasty pinch.  Your adapter may be possessed and decide to bite you!  There are voltages inside this little box that have unknown locations, so please be careful and make sure this adapter is unplugged before you attempt to rip it apart!

Now, a quick excerpt from Wikipedia that explains the ADC monitor connector - 

**********
The Apple Display Connector (ADC) is a proprietary modification of the DVI connector that combines analog and digital video signals, USB, and power all in one cable. Apple used ADC for its LCD-based Apple Cinema Displays and their final CRT displays, before deciding to use standard DVI connectors on later models.

First implemented in the July 2000 Power Mac G4 and G4 Cube, ADC disappeared from displays in June 2004 when Apple introduced the aluminum-clad 20", 23", and 30" Apple Cinema Displays, which feature separate DVI, USB and FireWire connectors, and their own power supplies.

The ADC was still standard on the Power Mac G5 until April 2005, when new models meant the only remaining Apple product with an ADC interface was the single processor Power Mac G5 introduced in October 2004. This single processor Power Mac G5 was discontinued soon after in June 2005.
**********

Once Apple decided to abandon the ADC connector around 2005, many people were stuck with really nice Apple Studio Displays that couldn't be used with a standard DVI connector.

Apple's solution to this was to sell an adapter that allowed you to connect your ADC monitor to a DVI output - so you could use it with newer Apple computers, as well as using it with a PC.

This 'instructable' is more like a 'take apart', since I won't be doing any modifications - just ripping it apart to see what's inside.

I did quite a few online searches and could not find any pictures of the internal components of the A1006 adapter, so I figured - why not put that information on instructables?!?

This was listed in the newspaper, and for a very reasonable price - they are still getting around $75 - $100 for them on ebay.  

The person told me that they were having to futz with the power cord - plugging it in and out of the adapter slowly, only halfway, etc. to get it to work.  Once working, it was fine until a power flicker or maybe a bump to the adapter.

When I went to pick it up the gentleman had decided that he didn't want to charge me anything for it because there was a good possibility that it wouldn't work.  I was happy with that, and agreed that if I got it working I would send him some $$.  

After lots of futzing with the power cord, trying a different cord, trying with a PC (a little easier to shut down and not cause any problems if you let the POST screen go for a bit), I could not get it to work.  It sounded like a loose connection with the power plug on the adapter, but after the following dis-assembly I couldn't find anything obviously fried.  

I'm now looking for more information on the power supply inside this adapter, so if you can add to the collective, please do!

Thanks for your instructions and info- I didn't think I'd ever see the inside of that thing. Trying to get the Cinema Display Piece working; I forgot about that connection issue (half way in, half way out, all the way in, 3 feet out);I have a feeling I'll be back here

Yeah, these can be tricky to troubleshoot since there's so little information about them.

I'm wondering if you could help me. I have this adapter and it works fine- but I want to connect this monitor to my 13" Macbook (came out in late 2008, aluminum but not a Pro, has intel duo processor and all that). However I'm going to need some converters to get it to connect, any clue which ones I will need? I appreciate your help.

hmmm, send me a picture of the connector on your macbook and I'll have a look!

awesome work, would be very interested in your results, I know that most of the Universities in my Area (Tennessee are constantly dumping the ADC LCD without these adapters, and the adapters still fetch a higher cost than the monitor can get.
Yeah, and that's sad because they monitors are pretty nice - especially considering their age.. I'd grab those up and at least auction them - or maybe donate them!

Hi, I just responded to another thread of yours here: https://discussions.apple.com/thread/5024209?start=0&tstart=0 . Hoping we can figure this bad boy out!

crakarjax - yep, I hope we can crack this egg as well! Not much info online, so I figured I'd at least post pix of the insides and maybe shake some info loose.. Planning on getting those pinouts to you in the next couple of days.. I'll post them here as well in case it helps anyone!
