Hi,
I´d like to put the sound-generator and amplifier of an Roland HP1700 into
an old HP1600 piano (keyboard is better).

Unfortunately the keyboard connectors are different. Does somebody know
the
pinnings??

thank you, Tomas.



Roland will happily sell you a service manual, won't cost that much.
