Image 58: GeoPort Telecom Adapter

GeoPort? What's that?

This isn't the place for detail, but GeoPort was a now-obsolete Apple technology that strove to use a Mac's internal hardware to emulate communications devices like modems or fax machines. For reasons I never fully understood, an add-on adapter – the item shown here – was also necessary, even though (as I understood it) the GeoPort Telecom Adapter wasn't a full modem on its own. (Interested parties can seek details online, starting with http://en.wikipedia.org/wiki/GeoPort .)

The TAM's GeoPort is, as far as I know, a standard unit of the type that shipped with other Macs of the era, with one difference: TAM-friendly color. (Other GeoPorts I've seen or owned are gray.)
