I just read that these are radiation leakage specs. A tempest computer should be well shielded so that EM and RF radiation does not leak out. There is speculation that enemies with well honed receivers can pick up classified information from this leakage. Zenith recently contracted to sell $300 million worth of Tempest Z150's to the army, navy, and marines. -- Kenton Lee, Bell Labs - WB 1D302, x7178 wb3g!kfl or hoxna!kfl
