Connect a performa to ethernet?

AAUI was part of a system of ethernet peripherals that tried to make connecting to ethernet much easier. At the time, ethernet systems usually were 10Base2, also known as thinnet. Apple's system was called FriendlyNet. A FriendlyNet 10Base2 system did not use BNC T-connectors or separate 50 Ohm terminators. The AAUI transceiver had two BNC connectors instead of one and a cable was attached to each side. The transceiver would automatically terminate the network if a cable was not attached to one of the sides. Additionally, Apple cables would terminate the network if no device was attached to them. Thus the number of mistakes that could be made hooking up a thinnet network was reduced considerably. Since any of these mistakes would disable the network in an area this was a significant improvement. However, the FriendlyNet equipment was quite expensive. As 10Base-T became ubiquitous it became difficult to justify the cost of an external transceiver and Apple abandoned the system and sold off the name.
