As things go with ASCII terminals, they're not very good at rendering
pictures. Since I'm trying this nevertheless, I possibly owe you some
hints on what this should depict. First, those rectangular things are
separate LANs, each run by its own department. The department name is
given below or above the picture, along with the subnet number. For example,
the Mathematics department is on subnet @code{149.76.4.0}. The Campus
Backbone has subnet number @code{149.76.1.0}. Those funny
@samp{[#]} symbols denote computers (can you see they're all
running X11? :-)

Some of them act as gateway between two LANs. These are shown along
with their IP addresses. For example the host connecting the Maths
Department to the Backbone has an IP address of @code{149.76.1.4}
when talking to the Backbone, and @code{149.76.4.1} when talking to hosts
on the Maths LAN.
