 The older PCBs have the speaker connected to PD3 (pin5). Since the 16 bit timer has to be used to generate accurate frequencies, you have to connect it instead to PB1 (pin 15). The pin to drive the transistor for the blue LED has to be moved from PB1 (pin 15) to PD3 (pin 5). The older PCBs have the speaker connected to PD3 (pin5).
