First, read All About AppleTalk for a primer on the network types

LocalTalk
• The easiest way to connect 2 Macs with AppleTalk is to just connect a serial printer cable between the Printer ports.
• Apple sold a “LocalTalk connection kit” with boxes that connected to the printer point and had 2 ports to daisy-chain Macs using proprietary 3-pin DIN cables
• Farallon created a cheaper method called “PhoneNET” where the proprietary cables were replaced with regular RJ11 phone cables


EtherTalk
• Ethernet is built-in to many Macs
• Early Macs require AAUI dongles to convert from the Ethernet port on the Mac to a more familiar 10Base-T RJ45 plug (or BNC)
• Macs without ethernet can have it added:
   • NuBus card
   • Comm Slot card
   • PDS card
   • SCSI adapter (Asante EN/SC or see Modern Hardware below for BlueSCSI)


Wi-Fi
• Apple AirPort
• AirPort-compatible cards (Orinoco WaveLan Gold)
• Some modern Wi-Fi routers or modern laptop Wi-Fi adapters do not pass AppleTalk

Bridges
Briges are used to connect LocalTalk and EtherTalk segments

• Dayna
• AsanteTalk
• Farallon EtherWave Multi-Printer Adapter
• LocalTalk Bridge is a software solution that can be run on a Mac that has both LocalTalk and EtherTalk
• Apple Internet Router can also bridge LocalTalk and EtherTalk networks

Modern Hardware
• BlueSCSI
• TashTalk2 Hat for Raspberry Pi
• AirTalk LocalTalk to LocalTalkoverUDP (LToUDP) via WiFi adapter
