I'm currently reverse engineering an old retro-computer interface board, by
tracing tracks with a multimeter and then transfering that to Eagle.
As I go along there are some pins that I have not yet traced, and others
that are not connected to anything. Is there an easy way of marking the
not-connected pins as such so that I can tell if I have not yet traced a
pin or if it is jiust not connected to anything.
