My thought too. There would need to be a 10baseT transciever IC for a
start.

I hope you're not suggesting that because I mentioned it came from an Apple
environment ;-)

I traced enough of it to convince myself that it's pretty well identical
to several other 10base2 transceivers I've repaired or otherwise taken
apart over the years, except for the built-in 50 ohm terminator and the
substitution of an RJ45 for a D-15.
