I read this at work and thought, I have recently dug out my 8865 instructions
and assembled the alternate model
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=18154
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=18155
and later motorized it with a 4.5 volt motor and I sure don't remember any
second set of motorization instructions. But there it is in the scans at
BrickShelf. So I checked my instructions at home and they are copyright 1988
and have only the pages for the 8700 motor set. The instruction booklet at
BrickShelf is copyright 1990 from the looks of it. The movement afforded by the
4.5 volt motor qualifies as a crawl.
