Step 6 Connect the Keyboard
The keyboard connector is a 5-pin DIN socket and is labeled KEYBRD and J3 on the motherboard. It will accept a regular IBM
AT-compatible keyboard. A 5-pin DIN to 6-pin mini DIN converter is needed to connect a PS/2-type keyboard.

Step 7 Connect Cables
When connecting chassis connectors to the motherboard, connect the correct connector end. Most connector wires are color-
coded. Match the color of the wires leaving the switch or LED to the same pin on the connector end. There may be more than
one connector with the same color-coded wires. If so, follow the wire to the switch or LED. Pin 1 of all connectors is labeled to
identify the pin orientation when plugging in cables.
