Includes power supply, manual, and cables but not the TV switch. Not tested - sold as-is. The computer looks mint except that one of the thin rubber feet is missing and the other feet show some wear; the cables have picked up some white material from the Styrofoam container. The container has some shelf wear and light staining.
Interesting that the manual is mainly about programming - back in 1982 I think most people bought these to learn to program.
