[time-nuts] Special connector for Symmetricom X72 rubidium standard

One source of that connector is an HP C8231A cable for a Deskjet 450.  
It's used to connect the printer to a DB-25 parallel port. The connector 
fits the X72, but there are only 25 leads in the cable.  I haven't tried 
to use it so I don't know if the missing lead is important or not.  The 
cable isn't molded so it might just be possible to add the extra wire. I 
opened it up, but I can't tell.  It looks like it's an IDC connector.  
The connector is stamped with the manufacturer's logo of 'JST' ( 
www.jst.com ).  No part number, though.  I looked at the web site, but 
didn't see anything close.
