Installation of Todd +5 Volt Supply
1. To install the replacement supply, slide it into place and install the front
mounting screws.
2. Feed the small multi-wire cable from the new power supply through
the hole at the top left of the +5V supply compartment (see Figure 4-7),
and on through the frame to the hole into the Multi-Output supply
compartment. If necessary, gain access from the front of the frame.
3. In the Multi-Output supply compartment, connect the connector on the
end of the multiwire cable to the mating connector at the top of the
circuit board.

other end of the multiwire cable is securely attached to the mating
connector on the circuit board.
