Panic, the developers behind apps like Coda and Transmit, spent some time disassembling the Lightning Digital AV cable that allows iOS devices like the iPad mini and the iPhone 5 to output HDMI to televisions.

Among other discoveries, Panic found an ARM chip and 256MB of RAM inside. There are a lot of questions. What OS does it boot?
