9) Chassis Intrusion Lead (4-1 pin CHASSIS) Also in Panel Connectors

This requires an external detection mechanism such as a chassis intrusion moni-
tor/sensor or microswitch. The sensor is triggered when pins 3 and 4 are opened.
If the chassis intrusion lead is not used, a jumper cap must be placed over pins
3 and 4 to close the circuit.

This connector supports the provided floppy drive ribbon cable. After connect-
ing the single end to the board, connect the two plugs on the other end to the
floppy drives. (Pin 5 is removed to prevent inserting in the wrong orienta-
tion when using ribbon cables with pin 5 plugged).

NOTE: Orient the red markings on
the floppy ribbon cable to PIN 1.
