   I have just received email indicating a claim that the new intel 486-sx
will not be pin compatible with existing 486's.  The source wasn't intel,
so I don't know...  If anybody has published or 'good' information regarding
final production, customer available 486-sx's NOT being pin compatible. Please
post the info and references.  I'll send a message to intel, but since it
is not a customer available production part -- today -- I don't think they
will make any comment.
