In the 80s, I played “Dungeon” (predecessor to Zork) on an accoustic-coupled teletype my dad brought home from JPL. It was running on one of the PDP-11s there. An intern from Caltech had altered the text of Dungeon so the story took place in the area (Flood Control Dam #3 was moved into Arroyo Seco). I went though a lot of fan-fold paper.
