There is some confusion as to what a GeoPort is.  Some people like to
call GeoPods (which plug into GeoPorts) GeoPorts, but this causes only
_most_ (as opposed to 'all') of the confusion.

A GeoPort look just like regular 8-pin Mac serial port, but there is an
additional 9th pin squeezed between two of the pins on the middle row.
However (and this is important) even if it looks like a GeoPort it might
not be one.  Some recent macs have 9-pin serial ports that look like
GeoPorts but they are not GeoPorts.

No, it is one (or sometimes both) of the existing serial ports.

Yes, but they are very expensive.  There are NuBus boards with
2 or 4 serial ports, or external SCSI devices with 2 or 4 serial
ports.
