I recently acquired a vintage Apple 30″ Cinema Display, which is a wonder! Requires dual link DVI or DisplayPort, but it’s glorious.
I purchased it at a Surplus event on Campus, which usually means I’m not early enough to pick much of anything because I didn’t roll in from Tornado Alley at 6am to wait in line for three hours, so I was delighted to see two of them up on a shelf at the register waiting for me. Works! Tested! With Power Adapter!
