Hey all- I'm doing a refurb on an old AT machine. The connectors that go TO the motherboard have the standard pin out with the one hole filled... they are "keyed" so they can only go in one way... only problem is, the mobo I'm using does not have the keyed pins. I know this is kinda old school computing but if anyone has any suggestions (like a way to take the plug apart to get the thingy out of the plug), I'd 'preciate it.

Huh?!?

Are you refering to the connector that looks like a small version of an IDE cable that connects the port on the case to a header on you mobo?
 
I think you're stuck. The one's for my old Asus board uses those keyed ones, and none of the others I have use them. I don't think you can modify them to work. Then I have an Epox board that uses non standard pin outs, so the serial cables I have don't work, even though they plug in just fine. I got around that one by using a USB mouse. Maybe you can get some from a computer stores junk box?

Yep, that's the one. I think that's the route I'm gonna have to go with it... either that or buy a PCI USB card for it which I'd rather not do. Oh well... thanks guys.
 
I'll double check but I don't think so. It'd be a heck of a lot easier (and cheaper) if it did because I do have an extra two USB ports that plug into mobo headers right here.
 
Look closely, most from 1996 on have one on there somewhere. Some of them have very strange pin outs, so keep your voltmeter handy for determining the +5.
 
If you can't dig the filler out of the pin hole then just bust off the pin from the motherboard.

my 2 cents
