I have an adapter that will be going on my A1200. I think I tried it on the Pegasos II earlier and it worked ok. You do have to watch for the chip type same as with scsi or sata cards. Right now both my A1200 and Pegasus II are down. (The Peggy won't post and the Ami needs hardware for the tower case) so I can't test that again. Though since all the systems (except the Amiga) have ethernet ports I don't know why you'd want to. The USB one is slower.
