If you used a spare header to daisy chain using ribbon cables, you'd save up
to 11 paddles per device, and only need 55 total.

The way that works is that instead of using a pair of paddles for "bus in"
and "bus out", you'd use one paddle, but it would have an "input" ribbon and
an "output" ribbon. It is my understanding that the devices essentially
wire a pairs of sockets 1-1 for the "bus in" and "bus out" connectors. (I
have quoted "input" and "output" because it is a bus, and there is no real
difference between them.)

Of course, that won't look quite right to whoever compares your hardware to
the manuals :-).
