In the fall of 2000, I bought one of the Apple 17' CRT ADC Studio Displays with my Cube.
It came with a flimsy little plastic and cardboard "Lollipop" thing. The disk portion of the lollipop has a hole cut in it, and it seems to me that it must be some sort of tool for calibrating or checking the colors of the monitor.
I have no idea how to use this thing, or for that matter, even what exactly it is used for. The "manual" that came with the display doesn't mention it or tell me how to use it. Can anyone here enlighten me?
