On the left is the most visible change in the remodeling, a new set of shelves holding reference material and networking equipment. On the right, a Macintosh SE/30 on the top shelf is used to prepare (via the network) Tutorial Room computers for classes. Below it is the monitor for the MkLinux server.
One of the most critical goals of the remodeling was making space for keyboards, mouses and computers; up to this time, any and all of these were piled up on top of one another, which often resulted in a keyboard or mouse taking a suicidal plunge toward the floor. (And yes, the plural for a computer mouse is "mouses.")
