Prototype Memory Unit for Xbox 360

Prototype accessories, especially for physically small accessories, can be hard to come by. That is what makes this 512mb Xbox 360 sample card interesting. Most people wouldn’t think twice if they saw one of these. Developers probably rarely used them, if at all, let alone cared enough to keep track of them. The video shos that there are some differences between the retail and proto card, even if they are minor.
