It’s not PhoneNet. It’s not LocalTalk. It’s Neither… NeitherNet!

With this adapter, available as a kit or fully assembled, you can use basic ethernet cables to connect your classic Macs together in an AppleTalk network.

Compatible with any Classic Mac with DIN-8 Serial Ports and AppleTalk installed. NOTE: This does not turn your serial ports into Ethernet ports, nor can you plug these into an Ethernet switch. It simply allows you to use inexpensive Ethernet patch cables in place of phone cables or serial cables to make a LocalTalk network.

Each unit comes with a fancy case, printed in Apple Platinum! You can also download the STL file and print one yourself.
