Many years ago, I saw one on eBay from a guy in Canada. I remember he said one of his teachers gave it to him. At the time I didn't think much of it so I didn't bid.
I didn't keep the photo. It seemed to be a normal back insert and manual, and the disc print seemed the same as production too, but had NOT FOR SALE (and maybe something else, can't remember) written on it, sort of easy to miss if you're not looking carefully.
Does anyone have a copy of this? Or have you seen one before? If the box looks the same, it's obviously like finding a speck of gold in a river, and I never really looked for it
