Cable for external DVD drive (IBM)

[stalepie2]

Hello,

I found an old external IBM DVD drive on my shelves. I can't remember if I ever had a cable for it, but if I did, I forgot what it looks like. Here are pics:

In the third one you can see a good shot of the port. What kind of cable do I need?

I bought it for an old X-series ThinkPad years ago, but don't think I ever got it to work. Maybe I just didn't have the cord. My memory's fuzzy.

Thanks
Matt
