connector is basically Apple's miniaturized version of the 15-pin
 DA-15 AUI connector which was originally used for 10Base-5 ethernet.
 External transceivers such as the M0437 are pretty much the same
 internally as a generic AUI to 10Base-2 or AUI to 10Base-T transceiver. 
 I beleive that while the AUI connecotr has a 12V power supply for the
 external transceiver, the AAUI has a 5V supply. So converting a
 transceiver from one to the other is more than just a connactor swap. 
 
I recall the same thing.
