A couple of 2600s, Colecovision, C64, Sega Genesis, a number of Game Boys, NES and I think there's an SNES somewhere too... also
VictorMaxx virtual reality goggles, got them at Big Lots for cheap, you use them with an SNES or Genesis but I have never tried hooking them up. They have a dinky little passive matrix LCD, Fresnel lens, stereo audio and an encoder that is supposed to move you left-right as you turn your head. I also have an Aura Interactor (basically a scaled-down Bass Shaker in a backpack).
