Sorry to say, it does not make any difference.
I for now also have found some other strange behaivors of the
EtherTalk card memory when using it from the 68020.

Where can I find a list of these bugs? (They must be known)
Where can I find a list of the rest of the bugs in the card?
What different revisions if the EtherTalk card are there now?
Which one am I supposed to have?

When will people stop making the misstake to let 3COM build
their ethernet cards?

Tired of debugging someone else's hardware
