What kind of connector is this? Looks similar to S-Video

Here's the pinout:


Never seen this type of connector anywhere. Also, this is for an old tape deck synchronizer, so this might technically be the incorrect subforum (or entire forum) to post this, but I think you guys would have a good idea about it. It's a 'computer' anyway

I don't think I'll be successful in finding both male and female connectors to make this cable, so I may just have to cut the short one I have and extend it somehow.

You got dimensions?
Looks like Hirose might make something compatible:

A search for 12-pin Hirose brings up a number of options:

I don't have access just yet, but I just got done looking through Hirose's entire website, and they definitely don't make the connector I need.

What is the brand of the tape deck synchronizer? Search on that brand? Probably a proprietary cable, or maybe it's an industry standard patch cable. Hard to tell since I'm not in that industry. Audio, sound equipment? Try a forum for that industry?

Hirose RP17 looks pretty close to what I can see in your pictures...
