TEMPEST was also the codename of the NSA project for leveraging emissions. And it has become code for machines modified to protect against such things. So a "tempest computer" (if you ever see one) is a computer hardened against emissions.

They're stupid expensive, those machines. A lot of places are finding that it's less expensive to maintain an EMSEC zone and run COTS equipment.
I've heard about them being used for an opposite reason. Rather than for security, they are used in places where you don't want to risk them interfering with other equipment, like a room with radar equipment that might be sensitive.
