One thing is bothering me after reading this review.
I do not have a personal experience with 8480 set, so I might be wrong, but looking on the image above I can see that one of the eccentric pieces is used as a cam - it pushes the corresponding buttons on the battery box when it's axle is rotated. (That matches the cam definition from, say, Wikipedia: "a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path").
However, Blakbird's Technicopedia on http://technicopedia.com/1994.html page states the following:
I see that Mr. Blakbird is here, so my question will be addressed directly to him - am I being wrong about the aforementioned mechanism or Technicopedia's entry on the "cam" piece is, say, not up to date?
(Oh, and a second question regarding that article - aren't there 4 axle holes in the cam piece, not 6?)
Please do not consider me being picky or rude, I am just really bothered by this issue and have no intentions of insulting anyone. In fact, I'm very thankful to Blakbird for the excellent encyclopedia site and to Lost_In_Noise for such a detailed review.
