Adding an OutputExpander Port

On Earlier Boards (REV lower 0.6) Pins of the Output Expander will have to be soldered directly to the 74HC595. Its the right Chip under the ATMega seen from the bottom Side of the Control Board (don't scramble the 2 74xxx chips, it wont work with the 74HC165!!).

Heres the PinOut:

Red=+5V(PIN1 of the OutPut Expander Port),

Blue=GND(Pin2),

Green=Q7'(Pin3),

Black=CLK(Pin4) and

Brown=EN(Pin5).

Now only Missing is CV1....
