J. Alex Halderman and Ariel J. Feldman hacked a touchscreen voting machine to play Pac-Man, without breaking the machine’s tamper-evident seals.

In celebration of the 30th anniversary of the iconic arcade game, they reprogrammed the AVC Edge, a touch-screen DRE (direct-recording electronic) voting machine, to run Pac-Man.

They found by removing screws and opening the case of the electronic voting machine they could replace the software leaving the tamper-evident seals intact. The video below shows the Pac-Man  being played.

How did you reprogram the machine?

The original election software used the psOS+ embedded operating system. We reformatted the memory card to boot DOS instead. (Update: Yes, it can also run Linux.) Challenges included remembering how to write a config.sys file and getting software to run without logical block addressing or a math coprocessor. The entire process took three afternoons.

(After the 2008 primaries Virginia banned the electronic voting  machines. Two were purchased for $100.)
