New Acquisitions

I worked at the Los Angeles Air Force Base in the mid 80's and
one of the requirements for personal computers of the time was
called TEMPEST. Computers meeting the TEMPEST specification
contained such hardware as necessary in order to ensure that
electromagnetic radiation emitted from the computer would not
be able to be monitored in such a way as to determine the use
to which the computer was being put. More simply, one would
not be able to eavesdrop on the computer user, since there would
be no discernable message in any electromagnetic radiation
coming from the computer. Perhaps this is what you have. This
would explain the extra shielding on cables and the double walled
chassis.
