It is 11 pages, if you want me to mail you a copy. I can see stringing the
X lines: solder one end to a printed circuit pad, put on the number of
cores, then solder the free end, pulling the wire tight. The enamel, such
as nylon, that one can solder through would be helpful. For the Y lines,
similarly, except you have to decide the orientation of each core and feed
the wire through. The sense line can be diagonal, or, another example,
parallel (both directions) to one axis. That axis is driven first and a
delay is given to wait for the noise to die down. Some of the other schemes
with closed spaced cores, I do not see how anyone could run the sense lines!
