(...) That would be my fifth book, and my second that contains pneumatic models. I'd love to do more models based on a single 8455 set. It has enough switches to make a half adder, and some cool walkers. It is a challenge to live within the (...) (21 years ago, 9-Apr-04, to lugnet.technic, lugnet.books)
