A20 Disk Drive Assembly
Install the replacement disk drive.
1. Connect the existing ribbon cable to the replacement disk drive.
Note
Make sure that the disk drive connector-contacts touch the
ribbon cable contact areas (the ribbon-cable contact areas must
face the contacts in the disk drive connector). Also assure that
the connector is properly locked.
2. Slide the disk drive and bracket assembly into the analyzer.
3. Route the ribbon cable through the side access hole. Avoid twisting the
cable-duplicate the original folds made to the cable.
4. Fasten the disk-drive bracket to the side of the analyzer frame, using the four
screws saved in step 4 (immediately above).
5. Remove the trim strip from the top of the front panel.
6. Remove the screw from the top left comer of the front panel. This will allow
access to one of the #2 hex screws of the disk-drive assembly.
7. Aligu the disk drive with the front panel, and tighten the three screws that
fasten the disk drive to the disk-drive bracket. Do not over-tighten.
8. ReCOMeCt the ribbon cable to the CPU board.
Note
Make sure that the CPU connector-contacts touch the ribbon
cable contact areas (the ribbon-cable contact areas must face
the contacts in the CPU connector). Also assure that the
connector is properly locked.
Test the disk-eject function, and adjust if required.
1. Insert a diskette into the drive.
2. Eject the diskette from the drive.
3. If the diskette does not eject properly, loosen and re-tighten the three screws
that hold the disk drive to the disk-drive bracket:
a. Loosen the two screws that are readily accessible.
b. Loosen the upper-most front screw through the access hole in the top-left
area of the front frame.
