Atari XEGS video game system at the Evercon Side Quest event in Rothschild Wisconsin last month. The Atari XEGS was the last Atari 8-bit computer, stylized as a video game machine. The idea was that between this system and the then-new Atari 7800 and their glut of legacy software support, they could reassert Atari into the video game market Nintendo had taken over in the late 1980's. It didn't work, though not because the machines weren't any good.
The game here is "Return of the Jedi" which in this level has the player pilot the Millennium Falcon at the battle of Endor.
