I have a copy of the Ethernet 1.0 spec and the IEEE 802.3, and the only difference I can see is in the pinouts and in the SFD and length/type feild. But I see no reason why the two would not be interoperable at the physical layer! Other than the pinout issue, and the fact that 802.3 supports signalling from the DTE to the MAU for mau_request and normal/isolate messages while Ethernet 1.0 leaves these pins unconnected. Thanks.
