reconnect the ribbon cable at connector J1. Connect the ribbon

itself into place and continue pushing inward until it is fully
seated.

Reconnect the disk power cable by inserting the plug P8 into
connector J8.
5 Return the processor to PRIME mode. On the status panel push
the P rocker switch down and turn the MODE SWITCH key.
The ONL lamp should go out.
If replacing a 380 MB, 760 MB, 1 GB or 2 GB Turbo disk or a
