I could swear I've run ITS on an emulator and had ethernet working.  I
don't recall if it was simh, however, but I think it was.

It was a while back, so I could be making it up, but I recall having to
bake the IP address into the ITS kernel image (doesn't everyone know
midas? :-)

As I recall we did this to get the lisp machine emulator talking to the
an ITS host.  Björn Victor <Bjorn at victor.se> would know for sure.  I'd
just ask him.  I think he got it to work.
