From time to time, there’s a wave of prototypes on eBay. This week, I’m going to show you a bit. To start with, something surprising: a battery.
Listed on eBay for $330, it’s a pre-DVT battery (meaning it’s at an early stage of development) for what was then called M42. I’ve already talked about M42: it’s the codename for the MacBook (M43 being the Mac Pro).
