I was able to procure a tempest specced HP Laserjet + (model 2686 TA), used around a year ago and recently did a motherboard swap to upgrade the unit to 2mb of RAM...wasn't all that much to rip apart and put back together...even with all the damn machined-screws and shielding, the thing still emits a fair amount of noise, but no farther than the room it's in...
How does one go about testing such a thing?
I checked all my cables and system box and switched to shielded cables and cleaned up the the noise as best I could...interesting design and at least I would see the damn snoops...they'd have to be in my front yard to pick it up...anyone else hack any used TEMPEST stuff?
Is there any way of Jamming a computers emmisissions? Just a thought. +----------------------+----------------------------------------------------+ | J.
