This one?
That page says it has a DB-15 (VGA) socket, and everymac is usually accurate with these things. Maybe, if that's not the right one, if you could find your exact monitor on their list, that would help us know what to suggest. If it is ADC, then yes, you need to power it from an ADC Mac, a Dr Bott DVIAtor (ADC to DVI adapter with power supply), or hack it/make up your own adapter cable, with an added 24 to 27 volt 3-4 amp PS.

The original trio of Apple Studio Displays (who differ mainly in their inputs and a few other options) do require an AC adapter. It's from the awful beforetime. Before the Dell Ultrasharps were invented.
Here's the adapter from a reseller: http://www.welovemacs.com/92241661.html
If I'm remembering correctly, the power adapter is a relatively common point of failure on those displays (along with the height-adjustable stand) and it seems like these days, finding one without those two items is way easier than finding one with them. (like here: http://cgi.ebay.com/270819267862 )
Here's the hack JT was talking about: http://hackaday.com/2010/11/03/normal-connectors-for-apple-studio-display/
That's an entirely different ballpark though and you shouldn't have to do that because the power and video and USB aren't integrated into one cable, like on the newer ASDs. Getting a pinout for the AC adapter should be all you need, and if I remember correctly, the connector is more standard than you think. (But I don't have one so I'm actually not completely sure.)
Good luck -- getting one of those to work properly could potentially yield a very nice looking setup.

Also for clarification, here are the differences between the three original-style Studio Displays (I have all three
The original dark blue one (in Bunsen's post) has an old-style Apple DA-15 video plug and an ADB hub in the (detachable) base. It also has composite and S-video in ports, as well as dual-RCA-jack audio in along with a 1/8" out. (It does not have speakers itself, it just converts the RCA audio into 1/8" plug.)
The second-generation is blue-and-white to match the B&W G3, and has a standard DE-15 VGA video plug. It is otherwise identical in connectors to the dark blue one. (Yes, it has and ADB hub in the base - this likely explains the B&W G3 having an ADB port.)
The third-generation is graphite to match the Power Mac G4 line, and uses a DVI port. It does away with the composite/S-video/audio ports, and replaces the ADB hub with a USB hub in the display itself, rather than in the base. (The USB ports are where the composite/S-video/audio ports were on the earlier models.)
All three use the same power brick, which has a standard IEC C14 AC socket on one side (the same as most computers,) and a common type 'post and barrel' DC socket on the other. The display has the post-and-barrel male end permanently attached along with the display cable. The Apple part number for this is M4551, "Apple Studio Display 45W Power Adapter", auto-switching AC 100-240V input, DC 24V 1.875A output (See also Cory's post for replacement info.) Yes, the power bricks are freaking expensive. They are the same input and output voltage/amperage as the PowerBook 5300-series bricks, and if you're inventive, you can create your own adapter. (I built an adapter from a spare 5300 power brick and a female post-and-barrel 'brick' from another device - a power conditioner for an HP scanner that uses the same physical size plug as the Studio Display.)

Yeah It is the ADB/ DB15 one that I "liberated". The rest wouldn't intrest me as much. It is the only lcd display available that can connect to an 68k mac and still have an Apple logo
further more it has an S-video and RCA jack in so that to will be rather cool to hook up an Amiga or console. I never new about these screens before, that is why I'm so excited. The design is also unique for mac an the only thing close is the eMate 300. I doesn't really looks like the imacs yet. I am a fan. Only thing missing of course is a power supply. I'll guess I'll be making one myself since I can't spend a 100 dollars on a silly power supply.

I'll guess I'll be making one myself since I can't spend a 100 dollars on a silly power supply.They most certainly did, I have an Apple "Centrelogue" released by Apple Australia that features it. Also, it was reviewed by Australian MacWorld. It was very, very, very, very expensive though, and as such I'd imagine they didn't sell many.I've literally never seen one of those first ones here in .au. I wonder if they even made it to our shores.
