Yamaha synthesizer manuals and tuning websites

Many thanks to Mr. Graham Breed for the link to Yamaha synthesizer manuals.
Yes, the TX81Z manual is there, and it will be very helpful, thank you!
I had been on that Yamaha site, but only thought the manuals were available
for the models they were featurning (!)

Incidentally, Mr. Breed's Website is one of the most informative and
educational on xenharmonics. Probably everyone knows that. The only other
two that come close are Kyle Gann's more general one and Joe Monzo's
dictionary-oriented one. Have I missed any "hot" ones??
