This mainboard was pulled from a Roland D-50. The board powers up, however the board makes a D-50 extremely slow to the point of making a D-50 frustratingly unusable. I have no clue why CPU cycles are slow. It could be a chip problem or a bad diode. 

A repair will require a skilled tech, and is not for novice or even some intermediate techs. It may require some surface mounted components changed. Be aware of this.
