I've been a visitor of this forum/site for a long time, and just decided to register today. I've seen many requests for pictures of the N64 mobo, so I took my 1996 (yep, an original) mobo and scanned up a couple of pictures of it. Now, this'll give you the basic idea of what you expect to see when you open up your N64 for the first time. As mentioned MANY times before, the dimesions of this board are roughly 6 1/4 inches across and 5 inches up. Enjoy
