Uh.. The 86x0 is not a dual SBI 785. The system design is very 
different, although yes, you could have two SBIs in there.

You can definitely have ethernet on twisted pair in an 8650. In fact, I 
do...

It's all just a question of getting the right transciever. The ethernet 
port on the machine itself is the standard AUI connector.
