The difference is most likely that the AMBRA does not have PCI slots but 
uses ISA slots. You can find ISA Ethernet cards on Ebay at 
http://search.ebay.com/isa-ethernet-card_W0QQfclZ4QQfnuZ1QQfsopZ1QQxpufuZx  
or in a surplus computer shop. Make sure to get the drivers for the OS 
you are using. Here is a site pictorially showing the difference between 
ISA and PCI Ethernet cards.
