Turbo Card controller

[BiohazardSEGA]

I just got two turbo card controllers, with what seems to be a NES connector. I found this one: http://image61.webshots.com/61/0/86/38/521708638MkeMsL_ph.jpg But mine looks a little different, they look more like a traditional NES controller in blue and silver. Does anyone know something about these controllers? I can't find any good information, except the picture I posted.
