Ah, I had wondered about that but was probably being a bit selfish  as I 
only have the GPS based units:-)
Given the similarity, I would assume where we've got to on these  wouldn't 
be a bad starting point, and at least identifying the 1PPS input on the  
interface connector should be straightforward enough.

No, once we get the GPS end worked out, we need to do the  same thing for 
the non-GPS end. If we can fake it into working with just a  PPS, it’s the 
perfect thing to use to attach an OCXO to a newer GPS (like the  Jackson Labs 
part …).
