NeitherNet Adapter

NeitherNet Adapter


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.

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

Download the pinout guide for self-assembly.


What the heck is NeitherNet? It’s a PhoneNet-style adapter based on a project called CapNet from the early 1990’s. It’s a crazy build-it-yourself solution that allows you to re-create PhoneNet LocalTalk networks for your vintage Macs without all the expense and risk of finding an original adapter on some auction site.
