B.12 Power LED and Keylock Connector (CN2)
You can use an LED to indicate when the CPU card is on. Pin 1 of
CN2 supplies the LED's power, and Pin 3 is the ground.
You can use a switch (or a lock) to disable the keyboard so that the
PC will not respond to any input. This is useful if you do not want
anyone to change or stop a program which is running. Simply
connect the switch from Pin 4 to Pin 5 of CN2.
