Am I correct in understanding that what's actually detected and reconstructed by TEMPEST surveillance is the EMR having to do with screen drawing, and not the CPU and other internal components involved in processing data? If that's the case, would computers without CRT-type displays still be succeptible to TEMPEST surveillance? Such as headless servers that might be running a BBS without a video card inside or a monitor. Or laptops, such as a Mac PowerBook with an active-matrix screen? Thanks, Doug
