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

  Now why anyone would use a RJ45 in place of the
standard DA15 I don't
 know, but certain companies are well-known for deliberately changing
 standards for no good reason. 
I hope you're not suggesting that because I mentioned it came from an Apple
environment ;-)

  It sounds simple enough to trace out the schematic in
about 10 minutes. I
 wonder how it compares to the standard 8392 application? 
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.
