NOTES
A board transfer occurs when a board is available and the machine is ready.
The Board Available signal and Machine Ready signal can occur at anytime, but board transfer does not occur
until both signals are present.
The Board Available signal is present until the board has left the machine.
The Machine Ready signal is present until the board has arrived at the next machine.
