Is there a way I can wire up a LED to sync with the built in ethernet card on a PowerMac 6100 motherboard?

There's no small LED already on there? If not, looks for points on the motherboard where one might be able to be connected...i've seen things like that happen before.

I'm looking around for a way to wire a LED to one of the data wires, because I'm assuming the other two options aren't there....

There is no LED or visible place for it on the mobo. But the port is AAUI and it needs a tranciever to get connected into a coaxial or rj45 network and those adapters usually have an indicator LED on them.

Do you want the LED to indicate any network activity or just the presense of network? If you just plug in a led with a series resistor it might take too much current and act like terminator. An operation amplifier voltage follower controlling a bjt which drives the LED should work fine.

The AAUI transcievers aren't to hard to get into. Just pry it open with a screwdriver, and the top and bottom separate. Then pull off the silver shielding, and there's the circuit :-P Didn't he say it was built-in, though?
