Sega 3 Cart Slot?

THON · Post by **THON** » Sat Jul 07, 2007 8:10 pm

Hi everyone,

Being able to look at a Sega Model 3 board would greatly help to understand this.

Last night, I completely desoldered my cart slot, and to my demise, it wouldn't pull out! That's when I noticed this little hollow circles that the screws firmly holding it to the board went through.

It's a bit hard to explain, but on either side of the cartridge connector there are little tabs, and on the bottom side of the tabs are what it looks like used to be little hollow tubes that were folded back on the board. This securely locks the connector on the board.

Fortunately, it doesn't look like there are any connections near these tabs, so does anyone know if I could just cut the tabs off somehow?

EDIT:

Hopefully this will help everyone understand:

I know what you mean. I tried to take a spare cart slot off of a model 1 board, and those tabs make it really hard to do so. Your best bet is actually to cut the plastic right before the tab, I recommend a hotknife or dremel for the job. But be careful, wouldn't wanna cut anything!

I second that. I accidentally cut 5 traces on my Genesis. Its a pain in butt to repair those thraces too.

Thanks for the information. The hot knife method sounds sensible, I'll try that.

For future reference, I think they're called rivets.

you could also grind the tops of the rivets, get them thin enough and they come right out

They're much like that, except ground down have a large whole in the middle. Kind of like a nut.

Heh ya, that's a rivet. I've dealt with Genny 3's before, I know what you mean.

Good to know, thank you

. I'll try the "hot knife method" tomorrow and let everyone know how it works out. I'm planning on making a SNES and Genesis combo unit. A lot of thought has been put into it already. However, I'm planning on keeping the SNES's connector where it is (it seems too complicated and I don't want to buy a heat/soldering gun). I would also like to stray away from using tact switches, and instead using as much of the original controller as possible. I think it's possible

Hot knife method; utter failure. This has to be some of the hardest plastic I've ever seen. I even tried using my soldering iron out of pure exasperation and it barely left a scratch.

I've decided to not make a combo unit (SNES/Gen) purely because I don't want to buy a new SNES. But, since now I'm working only with the Genesis, I'm DESPERATE to re-wire the cartridge slot.

I'm sawing this off.

Why can't you just drill the rivets out?

Much harder than it sounds. I went work on one with a drill/dremel combo, all it really does is make things look messy. Those things are HARD!

Ah yes, the Genesis connector. I was baffled by that rivet at first too, but it's actually easier to remove than you'd think. Don't need any knives or dremels... a pair of pliers will do the trick. Look at the rivets from the top of the board. The very top of the rivets will have a little "lip" which folds over the opening in the connector just a little bit. This is all that's really holding it in. Take your pliers and position them so that they just catch the lip of the rivets and squeeze. They should kinda bend and smash inward towards the hole. Do this a couple of times until the whole lip of the rivet is smashed inward, then just push it out with a small screw driver. I've done this twice already with both a Genesis 2 and 3, and was able to remove the connectors with barely a scratch. Hope this helps.

Thanks for the advice, everyone.

I ended up just sawing the mother off. Then I tore out the coonnector with some heavy duty... erm... grippers. Unfortunately, 3 pins on one side are not fully inside of the cart slot (2 about 3/4 of the way in, one about 1/2 or 1/4). I tried pushing them back in with pliers (from a toe-nail kit), but they wouldn't budge. I kind of shrugged it off, because I figured as long as the metal leads coming off of the game are at least touching the pins it should be ok. Someone please prove me right.

Yeah, everything will be fine as long as they're at least touching. That happens to me almost every time too. I get in a hurry, yank the connector off the board and OOPS... a few pins stay behind, still attached to the board. One of my SNES connectors has pins up and down all over the place, but they're still making contact with the game, so everything's fine. That one that's only in 1/4 of the way though, that's a little scary. But still, as long as it's touching... yeah.
