Harvey Casey?  I know the man,  I spoke to him on the phone any number of 
times during the period when we were a service center for those folks.  And 
met him and spent time with him and others there during the time that I was 
out there for two different P.A.C.E. seminars,  in 1986 and 1988.

What is it that they're asserting here?  Do they not want people to 
electronically distribute the old manuals?  The paper copies?

Here's the deal:  We had a shop,  and were doing service on a bunch of 
different brands,  including particularly Yamaha,  Korg,  and Roland plus 
some others.  I closed the shop in April of 1992.  At that point in time I 
took all of the manuals that I had to another nearby business that I knew of 
and worked with and told the guy who was running it,  "You'll perhaps use 
these before I do."  Only thing is,   they dont' work on keyboards there!  So 
recently I got an email from the guy talking about them doing a bunch of 
fixing up and needing the room,  and at this point the only thing that's an 
issue is transportation for me and those manuals -- my car is not currently 
inspected and I can't afford the fine I'd get for driving it without 
inspection...

I'll be getting a hold of that stuff as soon as I can arrange something.  If 
any of you guys are interested in any of it,  drop me a line offlist,  I'll 
put 'em in a pile,  and I'll sort things out once I get the stuff and get it 
here and figure out what I've got.  And then we'll take it from there.
