Hello randru, regarding what you want to do and is it to place an s910 plate on an s710 keyboard?
If so, it cannot be done since the connectors for the display are different, the same thing happens with the EIF card, the same thing happens with the S750, it cannot be done because the card is different, the keyboards that can do this are the following:
PSR-1000, PSR-1100, PSR-2000, PSR-2100
PSR-S500, PSR-S550, PSR-S550B
PSR-S770, PSR-S775, PSR-S970, PSR-S975
