Recently bought almost 80 of these PlayStation from a government surplus sale . From the paper work it came from the Air-force research laboratory. The paper tag on top shows that the had drive was safely taken out also the little tag on the left designate this system to have also been modified to be a cpu , Linux workstation these tag will need to be cleaned off as they look very fastened . I have shown a picture of the system powered up on a tv screen. PlayStation 3 only no other accessory like power cord , controller. Let me know if there is any questions .
