The following link has a very similar pinout for a 26-pin 
floppy connector: 


Compare it to the teac PDF mentioned in a previous post.  
There may be some standardization in the 26-pin floppy 

I have a number of very small laptop drives with this 
interface.  I've also been thinking of trying to hook one 
up to the CoCo.  I'll try it on a more expendable PC first.  
But if it works, I could have a floppy drive that sits on 
top of a CoCo floppy controller.  That would be very nice...

I found this post from google:


It looks like a few thinkpads might've used 26-pin cables...

And this TEAC floppy drive used 26-pin cables - I wonder if they're the 
same pinout:


Dunno if this helps much, but I hope it does.
