Safety Guidelines:
Whenever the rear housing of the computer is removed and before replacing a module,
you must
1. Discharge the CRT (shown below) and remove the anode cap.
2. Establish an ongoing ground by using a cable with alligator clips at both ends.
Connect one end to the anode aperture, and connect the other end to the metal CRT
frame (as shown below).
3. With the CRT discharged and the ongoing ground in place wear a grounding
wriststrap to prevent equipment damage from static electricity.
