I Have No Mouth, And I Must Scream

Probably Ellison's most well-known story. The tyrannical computer AM has taken over the world and now a few humans trapped inside it fight for survival. (Note: Palm versions of this story contain a character representation of a punch card graphic that the original story was published with. To view the original graphic see any of the other formats. The punch card graphic and the Palm character representation of it were approved by Mr. Ellison, and he tells us that both contain a message that few people have ever decoded.)
