The Philips 9AVMAC-074I is an adapter for connecting a VGA computer display to an Apple Macintosh computer (VGA to Apple DB15). It has four DIP switches which would be a bit of a pain to configure if you didn't have the original bit of paper that came with it. Luckily there is a table that contains the important information below (as well as a picture of the original bit of paper at the bottom of the page).
