This is the first version of Zork that Infocom ever released.
It was the only version released through Personal Software, who was responsible for the cover art of a barbarian, which the Infocom developers hated.
It was simultaneously released for the PDP-11.
It was the only 13-sector Apple II software that Infocom ever released, and its copy protection is different than all other Infocom disks.
