Yamaha CS80

Hi,

I thought I had the complete CS-80 service manual, but apparently not.

What I have is the big schemo, the tuning instructions, and the first 13
pages of the service manual from this site:
http://bermuda.ucd.ie/bridge/cs80.html

Is there anything else (more parts; possibly the whole service manual)
online?

I have the CS-50 and CS-60 (in paper form), but I just noticed how much the
CS-80 differs from these.

Thanks for any hints,

JH.
