The original closure was done on August 22nd 2011. That's almost 5-6 years ago, and I'd guess it was for low quality. I'm guessing cause I doubt anyone would remember why after so long. Gareth's edit went through - and Michael Kjorling bumped it up cause he was getting rid of the master-slave meta tag (Words Have Been Had).
And lets be straight here. Its 2017. Less people get the master/slave/cable select topology. We should probably find a canonical question or create a stellar question as the canonical one. Then open and close this as a dupe, if we so choose.
I'd totally do this but... I don't have any pata cables.
