One of those youtubers that goes to old stores (Retail Archaeology or something like that) came across a boxed version of Alpha Centauri at a thrift store or something and bought it because he thought it looked cool. I couldn't believe his luck. I would really like to have that manual again. If I remember correctly, it was more than just a manual...it had a lot of backstory and whatnot.
