Mark,
I think the subject of pneumatic sequencing is strong enough to stand by
itself as a chapter.

| (...) Well, there are books about Lego Mindstorms and now a book about Lego trains, both by AFOLs, so I don't see why not. Chapters may look like this: 1. Basics. Components and simple system. 2. Larger basic systems, up to Backhoe Loader (...) (21 years ago, 8-Apr-04, to lugnet.technic, lugnet.books)
