A2000 CR Internal Video Connector Pinout The A2000 CR enhances the internal video connector of the original A2000, while remaining completely upward compatible with the former machine. The original A2000 uses a 36 pin edge connector for a video card slot. This connector is the same kind as used for the slot extension of an IBM PC-AT. The A2000 CR adds a second 36 pin slot, directly nect to the first one, that supplies additional audio/video information.
