There was another manufacturer one of the really low budget cards, I
forget the brand but they were shipped in a box  which looked like a
dunkin's munchkins box.  If you bought several boxes of these, I think six
in a box and the entire package was $30 you were likely to find more than
2 or 3 with the same addressing.

These were 10 meg only and I can't for the life of me remember the brand.
Used the tulip driver for linux if that helps refresh memories.

Any solution which requires uniqueness also requires a singular ultimate
authority.
Even MACs aren't entirely unique.  Some places used to assign MAC
addresses like they assigned IP addresses and the NIC had to be
reconfigured for the assigned MAC.  An admin was freely able to assign a
MAC to Joe Blow using a 3Com or Cisco OUI without fear of retribution.  I
personally have never seen any use in such a thing but obviously someone
did.

manufacturer assigned macs are guaranteed to be globally unique.
A specific enterprise reconfiguring the mac is akin to an enterprise
using RFC1918 space.
      I have to agree with Mr. Shore here .  Mac addresses are NOT
      unique from ALL manufacturers '.' .  I do beleive that there was a
      a brand (maybe not USA) that the cadr came without mac-address
      hard assigned on the card ,  You HAD to ,  using their
      configuration tool assign one .  JimL
