This comes around every now and then.  The report has schematics -- 
they look like full schematics, but I have not checked to verify 
that.  The work seems to have been done by the Syracuse University 
Research Corporation, Defense Systems Laboratory.

Dunno how much NTIS is asking, but this report is available on the 
internet.  61pp, 10.7 MB.  Google is your friend.

Maybe it should be added to the Y2K manual, if it hasn't been already.

Best regards,
