Page "AppleTalk" Paragraph 14

A thriving 3rd party market for AppleTalk devices developed over the next few years.

One particularly notable example was an alternate adaptor designed by BMUG and commercialized by Farallon as PhoneNet.

This was essentially a replacement for Apple's connector that had conventional phone jacks instead of Apple's round connectors.

PhoneNet allowed AppleTalk networks to be connected together using normal phone wires, even existing runs already being used for phones.
