Somehow, mine doesn't have one. :-\ It
does have a repair warranty in the bottom container, so it was probably removed.
60->72 Pin (Famicom->NES) Converters aren't as cheap to find as those 72->60 (NES->Famicom) Converters, which pisses me off. I guess the latter were made due to the Famiclones.
FC->NES: I think some/most/hardly any are regional (I think mine is European). Many were meant to be used with the toaster although the Toploader virtually eliminates all problems you can have with it. Mine has a ribbon which I used the first time today.

And yes, those Christmas of '85 carts with Famicom boards & converters do exist - I have two of them, one of which is Stack Up (100% guarantee or else you've got something even rarer) & ExciteBike.
I always find myself linking to this:
