Apple Presentation System
The Apple Presentation System (APS) is an external module
that uses the 15-pin video output connector on the
computer, and then provides a video signal for a separate
television display or for recording on a VCR. The APS
supports video mirror mode, where the image on the
television display is the same as the computer’s primary
video monitor. The APS is required for video mirroring.
