Quoted from pindergast:Pinside doesn't constitute "the entire repair community", and I know at least a few Army certified technicians who find this practice awful. I appreciate there are differing opinions, but jumpers on junk boards have no place in the residential setting most of these machines are now in.
Jesus. We're soldering a pinball circuit board here, not wiring a nuclear warhead! I get that the wires are messy and ugly, but if they work, what's the issue? You can't be a total perfectionist or it will drive you mad.
I'd bet at least 50% of boards in existence have these jumper wires on them somewhere. That's a lot of "rubbish" boards!
