In this talk Mark will discuss the latest in his fixation with hacking antiquated and beloved hardware. Megatouch bartop games. The Megatouch was a fixture in many bars in the late nineties and early 2000s. After Mark bought a couple of the units used and discovered some dubious security features and familiar hardware inside, the idea to document the process of hacking and exploring the machine came about--with the ultimate goal of showing how much fun and learning can be had in the process.

The talk will walk through a dissection of the hardware used inside the games from zero knowledge to “geek,” including a custom ISA I/O card and the encrypted hardware key. I’ll walk the crowd through sniffing the key’s cleartext 1-wire bus to get the password, and explore what we can do with it. Then we’ll move over to the software side of things to find even more fun security fails and follies.
