      I just
checked out the weird card that was in the old PC. It's a
 MIL-STD-1397C communications interface. Here's a link to a site about the
 card (a Navigator II). <http://www.sabtech.com/productlist.aspx?str=27>
 I've never heard of this MIL STD before is anyone familar with it?  
NTDS, I think?   
 
  Yeap, Naval Tactical Data System (I just found that on the net.)
Surprised that I've never heard of it before.
  Its a fairly bulletproof serial bus. Military, but you
knew that. 
   Do you know if it's still in use?
