I found this Xbox 360 prototype at a thrift store in the Seattle area. Does anybody know anything about it or could point me in the direction of someone who would. I've talked to a couple other collectors in my area both of which have development launch team systems (the green sides) but neither said prototype or had HDMI. All serial #s match up (the back, USB ports, and system itself). I didn't notice anything different with it when I started it, just the old dashboard looking normal There's nothing on the HD that says anything crazy but it's probably not the HD it originally came with. I played some Halo 3 on it (I wanted an early title so no update) and it seems like a regular Xbox. I'm located about 20 minutes away from Redmond, WA so Xbox and Nintendo gems are found all the time.
