Notice I used the word "almost".

The diodes are for the Poly/Chord/Hold buttons that are not used on the EX-800. Other than that, there is ALMOST no difference.

Certainly for the purpose of troubleshooting and repairing an EX-800, the Poly-800 schematic is all you need if you know what you're doing.

I do not think the schematics are exactly the same.
For example, on board buttons and display, the number of diodes are not the same, the number of buttons is not the same.
So I think there may be other important differences.
That is why I am looking for the service manual of the EX-800.
