[Sherry Wu] sent in a link to her Apple Studio Display hack. She got her hands on the 17″ display which has a proprietary Apple Display Connector that rolls signals for DVI, USB, and 25V power into one plug. Convenient right? Not if you want to use it on a machine that has standard video connections. No problem, she got out her meter and figured out which wires belong to each signal. After some soldering she now has a DVI connector for the video, and a 24V bench supply is standing in for power until a dedicated unit arrives. No luck so far at getting the USB and hotplug detection to work but she plans to keep going until that’s accomplished.

Looks like you can pick these displays up refurbished for as low as $75. Might not be a bad addition to your home setup if you’re willing to do some soldering.
