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]
