Communication Slot

The Apple Communication Slot is an internal expansion data interface (slot) found in Apple Macintosh computers from the early to mid 1990s. It is used to add communication expansion cards like network adapter or modem to Macs and Power Macs.

A major complaint about this design is that when a modem card is installed in the Communication Slot of a Power Macintosh G3, the modem serial port on the back of the computer is disabled.[1] 6200 series computers that came with this card installed had the modem port blanked out (though the connector was still present).[citation needed]
