ISTR 7 cables between my -8/i and the first DF-32 in the rack. 11
doesn't sound outrageous to propagate *all* possible negibus signals
from one box to another.

I have only seen such cables come already attached to devices. I think
you may have to fabricate them.

Now... what you can do is to make a *double-sided* board and design it
to be universal. You'll just be using 50% of its potential.
