10BASE2 ethernet coax
Asante adapter for use with the Apple Ethernet networking system. The Thin Adapter (TN), or transceiver has 2 BNC coaxial ports and a RJ45 ethernet port. Thinnet coaxial cable is then used between two or more transceivers to network computers and printers. This adapter, like Apple’s is self terminating and requires no terminator or BNC T-connector.
Asante FriendlyNet adapter info is found here: www.asante.com/downloads/legacy/fn10tigra.pdf
Update: I found the Adapter to Mac cable (last pic) and it will be included. The remaining two do not have that cable.
