Internal Serial Port adapters
Griffin Technology has a number of exciting serial compatibility products for the Apple Macintosh computers. The gPort and g4Port adapters provide standard Mac serial ports that are compatible with all Mac serial devices. They support all Apple and third party serial and localtalk printers, midi devices, as well as any other serial device that works on a Mac.
The gPort, g4Port, and CubePort use the modem slot on the G3, G4, or G4 Cube so they provide "board level" compatibility, even supporting Localtalk file sharing and printing to your existing Localtalk printers. The gPort, g4Port, CubePort take only moments to install.
something i didnt catch the first time around:
if u have a g3 ppc u need the "gPort" version
if u have a g4 ppc u need the "g4port" version
and if u use mac os 9.04 or higher u need to get the driver extension v1.03+ or higher
The iPort adapter also provides a Mac serial port for iMac computers that is compatible with all serial devices. And like the gPort adapters it supports Localtalk printing and file sharing. The iPort also provides video out for a mirrored display connected to your iMac. It is compatible with the original Rev A and Rev B iMacs (233 Mhz).
