'Super' Nintendo floppy cart connector question

So, I've been looking at Ben's 'Super' Nintendo page for longer than I'm going to admit and I just can't figure out that cartridge slot. I'm guessing it's made from both ends of a floppy ribbon cable. Please correct me if I'm wrong. So, obviously these connectors need to be modded to allow the edge connector to be inserted. That's a great excuse to break out the dremel. But, how does it work? What other modification is necessary? I mean, we are talking about your good ol' 3 1/2" floppy drive connectors, right? I don't see how that would work. I mean, it's been a little while since I've taken a good, hard look at one, but I just can't comprehend it. How can one of those be modded to accept card edge contacts?

It is just ribbon cable with the ends cut off soldered directly to the SNES board and to the corresponding pins on the SNES's cartridge slot.

yeah, he used two hacked up floppy drive cable connectors. apparently the spacing for the pins is perfect. it doesn't have anything where the middle pins are meant to be, but that doesn't matter for games since those pins were meant to connect to the expansion port of the nes.

his nes micro shows a closer pic of this method. i'm assuming he simply dremeled off the inner sides to allow for the nes cart to insert. then of course, you need to make sure that the spacing is correct and then make sure to secure them well so that they stay lined up correctly.

it's a lot easier to simply use a yobo's (or similar) cart slot...

The problem is that no FDD cable I've ever seen looks like that; they are instead like this:

How you can get even a part of a NES cart into that is a mystery to me.

it's gotta be the edge connector style.

As lovablechevy said, you need two old 5 1/4 inch connectors, not 3 1/2 inch ones. You need to get rid of half of the plastic on one side of each of them and get rid of this plastic thing that prevents you from inserting an edge connector the wrong way. Then you need to glue them together so they look like this:

Ignore the missing pins, I removed them because they're not necessary in an NES to Famicom adapter.

The NES connector uses 0.1" (2.54mm) spacing doesn't it? One can buy 72 pin 0.1" card edge sockets. That's save a lot of time lining up and gluing and whatnot. I don't know about getting one that you could crimp a ribbon cable on to, but that should be doable too.

Just an idea.
