There are no hardware differences between 802.3 and ethernet v1.0 and v2.0

Now there are some protocol differences in how the packets are 
laid out, specifically in the legth field and when packets are < 46 Bytes.

There is no hardware incompatibility (Physical layer) . There are some
problems at the Media access control layer. Read the Bridge document
on ethernet 802.3 compatibility.  So the products may not exactly talk, they arenot mutually exclusive and with a little tweaking can be made to communicate.

Your right it is naive, but we all start that way.
