The Reason I think the 7000 is the same is back when they first came out in 95 I had installed one. One of the ethernet IP cards went bad. Got a replacement and I installed it. I then noticed the MAC was the same which thru me off and I thought I reinstalled the wrong card, put the original card back in, same MACs. I then learned, after digging, that the MACs were derived from a chip on the backplane. Don't have a URL to prove anything though just my memory which can be hit or miss;)
