Yes, I have two. I have added some code to the SCN driver which
detects whether I have scn2681, scc2692 or sc26c92 but that is as
far as I have got. One gotcha is I was working of a "preliminary"
data sheet for a while which is definitely wrong!

In the US I don't know, but it wasn't toooo hard to find them in
little old oz, so I imagine it wouldn't be too hard in the US. Find a
Phillips distributer.

I got mine direct from Cabletron Australia. It is an ex demo unit.
You may have trouble convincing Cabletron that they did make such
a unit, but there is a reference on the cabletron web page. I 
haven't saved a URL, but one of the search engines should help.
