PM 6500: Video-Out Connector Interferes with PCI Card
The Power Macintosh 6500 & 5500 series sold in the education channel comes with an NTSC Video-Out Connector installed. This connector connects the computer to a television and displays the video image from the computer directly onto the television screen.
On Power Macintosh 6500 computers, the NTSC Video-Out Connector card, which plugs into the monitor-out slot, is too tall and interferes when installing a PCI Card in the lower PCI slot.
Apple is aware of this issue and has redesigned the NTSC card that plugs into the monitor-out slot so that it no longer interferes with installing a PCI Card in the lower PCI slot.
