It brings back some fond memories, doesn't it? I remember some evenings probably very similarly to what you recall. In the office late at night, with the lights out and the only thing illuminating the room was the frontpanel to a Data General Eclipse C330 and the master console. Type a sentence, and the lights flickered, Zebra drive shaking like a washing machine on spin cycle from the inertia of its massive 90 pound linear motor.Like you, I kept the printouts. They made a sort of a story book, and a good one at that. I actually have a printout on greenbar paper - now yellowed - that has the entire story, start to finish. I completed the game in order to make a complete printout that would form a book.
Remember the control room at the dam? How about the coal mine?
