To install a new system board:
The new system board should have the SIMMs and WRAM module (if required) installed before
placing it into the base unit.
1. Lower the new system board into the base unit. Ensure the standoff lines up with the hole in the
chassis. Slide the system board to the back of the base unit so the external ports fit into the back
panel.
2. Install the eight grounding screws.
3. Install the hex nuts onto the audio jacks.
4. Install the jackscrews onto the video, parallel, and serial ports.
5. Connect the MIDI (or game) and CD-ROM audio cables to the system board.

are labeled with the corresponding system board connector.
7. Connect the LED and Reset cables to the system board.
NOTE The orange wire for the disk activity LED cable must connect to pin 1. The white wire for the power on
LED cable must also connect to pin 1. The orientation of the reset cable wires is not critical.

system board.
10. Install the system hard disk drive and connect the SCSI cable to the system board.
