This vintage Apple Monitor III Model A3M0039 is a true piece of computing history. Manufactured in April 1983,  It is compatible with Apple products and would make a great addition to any collection of vintage computing equipment. The monitor has a classic design and is perfect for display or use with vintage computers. Don't miss out on this rare and functional piece of tech history. Unit turns on red light by power switch works lovely green screen. Front screen on monitor is ripped in one area see pics. I did not plug anything in to see if it actually displayed words. But I am assuming that it will work as the screen did turn on. So this is why I'm listing it as parts.
