There's no stopping this guy, and now he's built himself an Atari 7800 portable just to make sure the kiddie hackers know who's the Heckendornest. Ben Heck built the 7800 portable with a 7-inch widescreen to accomodate that larger motherboard on the 7800 (compared to the 2600). Apparently large, complex motherboards just don't phase him anymore. The unit boasts rechargeable batteries, a combination driving / paddle controller, and an A/V output jack. Ben, you're a legend.
