I'm sorry, but I decided to delete them once I noticed that the service
manual contains the same schematic diagrams in better quality.  I should
have the paper originals, but they are of very bad quality.  Instead of
putting the files back, I could create links for the schematic diagrams in
the service manual.  Done.  (There should maybe also be a summary for each
