360K Floppy Drive  (250-1005)    Installation          Faxback Doc. # 5347

We recommend that you have the Secondary Disk Drive installed by the
service technicians at your Radio Shack Service Center.  Doing so not only
ensures expert installation, but also enables the technicians to quickly
check to make sure all the equipment is functioning properly.

If, however, you do decide to install the kit yourself, follow these steps
exactly:

1. WARNING: Turn off all equipment.  Turn the power off and disconnect the
   power cord from the back of the computer.  If the computer is on, you
   could damage the central processing unit, as well as your Secondary Disk
   Drive.

2. To avoid possible static charge build-up, touch a metal object to ground
   yourself before you begin.

3. The Tandy 1000 Disk Drive Kit consists of the following parts:

     * the disk drive
     * two small screws
     * one long screw

Be sure the disk drive in this kit matches the disk drive in your computer.
Pay special attention to the drive light and door latch.  They should be
positioned the same as those in the drive in your computer.  If they do not
match, see your Radio Shack dealer.

4. Remove the two screws on the front of the main unit.  Remove the cover
   by sliding it away from the rear of the unit, parallel to the computer.

5. Facing the front of the main unit, locate the screws on the right side
   that hold the primary drive (lower drive) in place.  Loosen these screws
   without removing them.

NOTE: Right and left mean your right or your left as your face the
      computer.

6. Slide the disk drive into the drive mount directly above the first
   drive.  Make sure the drive light and door latch are on the same side
   as they are on the primary drive.  See Figure 2.

7. Insert the two small screws (included) into the mounting holes on the
   right side of the drive mount bracket.  Notice that the drive mount
   bracket has an upper and lower set of holes for each drive.  When
   mounting the secondary drive, place the screws in the set of holes that
   corresponds to the set used for the first drive.  See Figure 2.

   For example, if the first drive's screws are in the lower set of holes,
   use the lower set of holes for the second drive and vice versa.

   Do not tighten the screws yet.

HINT: You may have to lift the drive slightly to align the holes.

8. Insert the long screw through the clearance hole on the left side of the
   drive mount bracket and into the appropriate hole of the disk drive.
   See Figure 3.

   Tighten this screw completely.

HINT: You will probably have to get eye-level with the computer to see
      where it goes.

9. You can now tighten the screws on the right side.  Tighten both drive's
   screws.

10. Look at the back of the drives and locate the 34-pin ribbon cable that
    is attached to the first drive.  Connect the other end of the cable to
    the card edge on the right side of the second drive.  Do not twist the
    cable.

11. Next, connect the 4-pin power connector to the connector next to the
    card edge.  This connector can only be connected one way.  Do not force
    it.

12. You must remove the plastic panel that covers the drive opening in the
    case.  To do this, place both thumbs on the outside of the cover and
    push in evenly.  The cover should pop out.

13. Before replacing the main unit's cover, check all connections and be
    sure all screws are tightened.

14. Replace the main unit's cover and its screws.

15. Carefully remove the shipping card from the drive slot.

You can now use your new disk drive on your Tandy 1000.  See your
introduction manual or your applications manual for instructions on using
data diskettes.

NOTE: The small screws that came in this kit may have metric threads.  If
      you lose one, your Radio Shack dealer can order an replacement.
