I dug up schematics of the three versions of the SP-600 IF output, 
highlighted the signal paths to make the differences easier to spot, 
and added the information on how to tell if an SP-600 needs to be 
modified and, if so, what to do.  If you have an SP-600 and would 
like a copy, send me an e-mail OFFLIST.  (Repeat -- OFFLIST.)
