need help on controller hack

ok question everyone: I ordered the turbo duo extension cord from TZD. Now 
the packaging says it is a 6ft extension cable for a macintosh. So I say ok, 
it's just a stupid macintosh cable and go out and buy one for $3.99 only to 
find out that the connectors are wrong. Is this just a standard mini din 
cable that can be purchased, or is this actually a custom made cable that is 
only offered by TZD? I am trying to do the NES controller hack, but at 9.99 a 
cable, it isn't really worth doing. Already did the electrical hacking on the 
controller, just need the cable cheaper. Thanks
