"TEMPEST" standards are there to afford proper sheilding to prevent
radiations/emmisions fromt he machine when it's being used for security
information. The thicker covers, ground braids and multiple screws in the
covers make it better sealed and there should be no emmisions over 12 inches
from the machine, or none at all ideally. Other than
the power supply being a
class A type, the rest is normal but may have been refitted
with a shielded
faceplate.
