The RTL8019 is a well known ethernet chip that is a NE2000 clone. It has no memory on chip and uses programmed IO for communication afair. This requires a zippy cpu and lots of programming to make it work. Peter -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
