SBC-676

Power LED and Keylock (CN1)

You can use an LED to indicate when the CPU card is on. Pin1 of
CN1 supplies the LED's power, and Pin3 is the ground.
You can use a switch (or a lock) to disable the keyboard so the PC
will not respond to any input. This is useful if you do not want
anyone to change or stop a running program. Connect the switch
between Pin 4 and 5 of CN1.
