So all that needs doing is to get that section as a schematic and do
the board. :o)

It has an auto-router but it's not the greatest. It can come up with quite
reasonable results if you set a high penalty on vias, but sometimes makes
really silly decisions. I find I get best results by hand-routing busses
and timing critical tracks, then autorouting the rest. It does pretty good
with 4-layers. But then, it is a $1200 program.

They're ok for prototyping and for getting a 2nd opinion of your own
routing. I can live with that. :o)
Could you see it in your heart to get that specific part of the schematic
and send it to me? I wouldn't disclose it, and could move things forward a
little.
I'll check on the Q60 web site for the specs on their implementation of
the ISA slot.
