     Well, it turns out I was wrong about the history of Kay 
Electric Co. There is a short history of Kay Electric at: 
http://www.jproc.ca/rrp/sonagraph.html

     I confused it with Kay-Lab, which is now Cohu. For this 
history see:

    There are a couple of commercial handbook dealers 
offering Mega-Node Sr. books but none of the free sites 
seems to have anything.
