External switches and LEDs

Power LED and keylock (KEY LOCK)

You can connect an LED to indicate when the CPU card is on. Pin 1 of KEY LOCK supplies power to the LED; Pin 3 is the ground.

You can use a switch (or a lock) to disable the keyboard. In this state the PC will not respond to any input. This is useful if you don’t want anyone to change or stop a running program. Simply connect the switch between Pins 4 and 5. The pin assignments appear in the following table:
