INTERFACE BOARD INSTALLATION

We recommend that your local Radio Shack/Tandy computer center personnel
install the interface board to ensure the best possible installation. If
you choose, however, to install the board yourself, follow the
instructions contained under "Installation Procedures."

CAUTION: Before handling your interface board, touch a grounded metal
object to discharge any accumulated static electricity. If you discharge
static electricity accumulations through a circuit board, you could
destroy the board's integrated circuitry. Also, do not stand or walk on
a carpeted floor while handling any circuit board.

INSTALLATION PROCEDURES

1. Inspect the board to ensure that all the components are properly
   attached and undamaged.

2. Check the two option jumper pins located at the right-center of the
   board, and confirm that the jumper connector is attached to only one
   pin, as illustrated in Figure 1.

NOTE: The option jumper pins are pre-positioned at the factory for a
      single drive installation. If your DCS unit contains two drives,
      connect the two pins with the jumper connector provided.

WARNING: Turn off the power to all the peripherals and the computer.
         Ensure that the power cords from the peripheral equipment and
         the computer are disconnected from their electrical outlets.
         Any unit that remains connected to an electrical source is a
         dangerous electrical shock hazard. It also is a potential source
         of damage to the central processing unit or other integrated
         circuitry.

3. Disconnect and remove the display monitor from the system and set it
   aside.  (See Figure 2.)

4. Position the Tandy 2000 main unit so that the back of the unit is
   readily accessible and free of obstructions as illustrated in Figure 3.

NOTE: Option boards are installed in the card edge at the back of the
      main unit of the Tandy 2000 system. if you have a monochrome
      graphics option board, it must occupy the lowest slot. Any other
      empty slot is suitable for the DCS Interface board.

5. Select an empty slot. Pull the lock buttons on either side of the
   panel strip covering the selected slot. (Refer to Figure 4) to free
   the panel from the back of the main unit. Remove the panel strip and
   discard. The panel strip is replaced by the interface board assembly.

6. Discharge any static build-up by again touching a grounded metal
   object.

7. Pull the lock buttons on the cover panel attached to the interface
   board and slide the board's metal panel into the slot. Push it all the
   way in, ensuring that it seats firmly with the connectors attached to
   the computer. Then push in the lock buttons to lock the board in
   position.

8. Re-attach the display monitor to the Tandy 2000 processor, and re-
   connect the main unit's power cord.

9. Re-connect the electrical power cords of your peripheral units.

10. Refer to your DCS User's manual for instructions on connecting the
    DCS to your system, and for introductory disk cartridge handling
    procedures.

If you have read the Tandy Disk Cartridge System Owner's Manual, you are
ready to install the software, format the disk, and begin using your
Tandy Disk Cartridge System as detailed in Chapter 1, Software
Installation; Chapter 3, Disk Cartridge Preparation; and Chapter 4, Using
Disk Cartridge Utilities.
