Although the modem ports* on these computers do have nine pins, the ninth pin is not functional; the port is not a GeoPort. The GeoPort Telecom Adapter is the interface to the phone system and requires a GeoPort connection on the computer. Because these computers do not have a GeoPort, you cannot use the either the GeoPort Telecom Adapter or the Apple Telecom 2.0 software.
*Note: Some of the Macintosh Performa computers mentioned here may include an internal modem. When an internal modem is installed on these computers, the modem port is covered.
