It is obvious you don't see the connection. I will spell it out for you. Do you not agree that speeding up the clock will speed up the motor? If you don't then you obviously don't know that the rate at wich the FIFO is emptied is also controlled by the clock, therefore the clock speed obviously effects the speed of the motor. In the context of the problem that was originally posted, my statement is exactly correct. By the way, my old magnovox does not have a FIFO.
