Converting TTL monitor to Analog

        I don't know about the rest, but Apple's DVI connector has 24
pins. I'm not sure how many are on their latest connector, the ADC.
It goes back to something similar to what the NeXT did: it carries
power, video, and USB through the single ADC connector to/from the
LCD. Belkin makes an adapter that converts between the two though,
at least for connecting DVI displays to ADC graphics cards.
