HP VR1000-100 Windows Mixed Reality Headset. I've had it for about 3 years. I used to use it with my old computer, but now I have a mac so I have no need for it. Hoping to put whatever I get from this towards a Ovulus Quest. Last time I used it was about 4 months ago and it worked great, but I no longer have a windows PC so I cannot test it. Controllers definitely work and I have all of the cables.
