Playing Maze and Haunt at PARC back in the day... (Score 1)

My dad worked at PARC in the 70's and 80's and he would bring my brother and me to his office on the weekends. He would put us in empty offices and we would log onto the mainframe and play Maze all day long. We also played Haunt! which was a text-based adventure game. Does anyone know anything about Haunt!??? I would love to find it and play it again, but I have had no luck searching for it on the web...
