Although it looks like the terminator's faceplate, it is actually a bent Faraday cage / rf shield from an emac. (below is the unbent one straight from the emac)
These were included in the design to limit human exposure to potentially harmful rf, and to prevent Van Eck phreaking. But they look so much cooler as terminator-style masks.
Wire recorders store audio by magnetizing a fine wire and storing it on a reel for playback. The wire moves by the heads at about 24 inches per second.
This wire recorder was manufactured under license from the Armour Research Foundation.
We haven't got around to turning it on yet, and we are considering encoding data into audio and eventually using a wire recorder to store pictures and other data.
