Minecraft wiki entry for 0x10c, associated text: Of particular interest was the in-game computer, the DCPU-16. This was a fully functioning emulated 16 bit CPU that could be used to control your entire ship, or just to play games on while waiting for a large mining operation to finish. Full specifications of the CPU were released soon after the game's announcement, so the more programatically advanced of the playerbase could get a head start.[12] These specifications, along with the specifications for several pieces of in-game hardware that would have been able to interface with the DCPU-16, can be found here.
