I contacted Keith Peshak and received these links:
http://www.collisionavoidance.org
http://www.gtwn.net/~keith.peshak/Papers.htm
He briefly discusses the Vincennes shootdown of Iran Air A-300, but doesn't go into the lengthy explanation that was in the white paper.
I've worked with and on a lot of old transponders, Narco, King, etc., up to Arinc style, and I never saw one that didn't reply to Mode C interrogations with framing pulses.
Contact me offline if you like.
