CPU Board
The CPU board contains a series of LEDs and buttons that indicate the
current state of the machine. When the green LED is illuminated, the
CPU board is receiving power. When a red LED is illuminated, a
particular subsystem is experiencing failure or it may be a warning
condition. The display may reflect the fault.
Each CPU button has multiple functions based on the state of the
machine when the button is pressed. The button may be held and the
machine powered on or the button may be pressed after the machine is
powered on.
NOTE: If ALL LEDs are lit, the software has been erased and the
machine will not function.
