A Google search for "MIL-STD-1397C" had 149 hits.  From one PDF I
looked at:  "The Naval Tactical Data Systems (NTDS) interface
(MIL-STD-1397C) is a point-to-point communications specification used by
nearly all of the Navy s peripheral devices such as monitors, radar
systems, printers, tape drives and encryption devices, in order to talk
to legacy host tactical computer systems."
    A few names are very recurrent, such as Sabtech, Wind River, and GET
Engineering.
    I've seen it referred to as obsolete by some vendors.  I don't know
exactly what the context of "obsolete" is.

     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?
