On the old 3Com network cards that have AUI adapters (ie really old, the cards I was dealing with were 4 years old at the time - and this was 4 years ago), if you look on the back of the adapter, in tiny print you will see about 15 names of the team that designed the card placed randomly between circuits. What's best is that in the lower right there is one that goes "and of course," then the name.
