Radio Shack CCR-81 Reference Handbook

Disassembly
1. Position the Computer, keyboard down, on a
soft surface.
2. Remove six screws from the bottom of the
Case. Keep track of the different lengths so
you are sure
to replace them in the correct
holes.
3. Turn the Computer right side up and carefully
separate
the case halves.
NOTE: There are two different types of LED
mounting
A. Keyboard PCBs which are double-sided,
with plated holes use an LED mounted into
the top half of the Case. Long wires con-
nect the Keyboard PCB and the LED. Slip
the ring off the LED socket body (using
needle-nose pliers). Allow the ring to slide
down to the Keyboard PCB. Use the eraser
end of a pencil to push the LED down
through the plastic Case. Bend the LED
leads slightly to prevent the retainer ring
from getting lost.
B. The second mounting technique has the
LED soldered directly to a single-sided
Keyboard PCB.
The top half of the Case
simply fits over
the Keyboard and the
LED.
4. Set the Case top aside. Carefully lift the Key-
board out of the Case bottom. Take care that
you don't strain the Interconnect Cable.
5. Notice
the five rubber spacers which separate
the two PCB's. Keep in mind where they are
positioned so
you replace them over the same
plastic studs.
6. Carefully lift both boards out of the Case.
Take care you
don't strain the interconnect
cable.

7. Carefully layout the two PCB's, side-by-side
on your working surface. Again, avoid putting
strain on the I nterconnect Cable.
