Detective Comics #468

In "Battle of the Thinking Machines," Batman faces off against a rogue network of sentient machines, including the cunning Calculator, who's proven nearly untouchable by the Justice League. With the city under siege and logic turned against him, Batman must outthink a foe who's already beaten the odds—while a mysterious figure named Slud-Jak stirs chaos on the coast, drawn to the promise of Twinkies. Written by Bob Rozakis and illustrated by Marshall Rogers, with inks by Terry Austin and letters by Ben Oda, the issue's cover by Jim Aparo captures the clash of man and machine in sharp, dramatic detail.
