Nice find.
The reviewer missed one difference between the LC475 and Quadra 605: the Quadra 605 came with a PDS ethernet card fitted (at least in Australia, anyway). The only difference between the two motherboards was the position of a single jumper, so that "About this Macintosh" correctly identified the machine as an LC or a Quadra.
